New LS1 Owners - Newbie Tech - 10000 mile oil changes

Just wanted to know if anybody here has gone with a synthetic oil that goes for 10000 miles without changing? I got this oil and have 5000 miles on it. I recently had a low oil light come on, but I put 1 quart of synthetic oil and light went away. All I want to know is if anybody has actually gone 10000 miles without oil change on synthetic oil and not have any issues.

no do not be a cheap ass and buy that bullshit. buy the good stuff and change ur oil every 3000 miles. oil is your cheapest insurance

I change my oil every 5k with a synthetic oil....no problems.

Change your oil every 3-5k. That 10k crap is BS

Thanks for the responses so far. I forgot to mention that the place I went for the oil change uses Mobil 1 synthetic oil. They say that you can go 10,000 miles between oil changes. I do not doubt that other cars could go this long without oil changes. However, is this a good idea for our type of cars? I am right at 5,000 miles. Just wanting to know what to do. Should I go another 5,000 miles or just do another oil change even though place I did my oil change at said I can go 10,000 miles between oil changes?

Assuming you have an LS1 (make a sig man with your info!) don't cheap out and wait for 10K to roll around. If you want to make your engine last change the oil every 3-4K. Little things like frequent oil changes and using premium fuel keeps things smooth.

Ahem. I'm a shop manager at a lube shop and to be honest with you, we tell customers that ALL DAY LONG so they'll spend money on the synthetic stuff. The truth is that oil, no matter what kind, starts to break down long before it's actually time to "change" it. 10K miles is waaaaaay too long to have any kind of oil in any motor. Now, the Bimmers, Minis and other Euro-trash cars seem to go once a year or 10K between oil changes but...we don't drive Euro-trash, we drive American cars that need all the help they can get. You know what, even if I did drive Euro-trash I wouldn't wait 10K to change my oil; I don't care what my car computer says...

I change mine every 5-7k miles just depending on how it looks on the stick, how I've been driving that time, and if/when its a little low

i will be the only one to say that you probly can go 10,000 miles on a oil change, with the proper used oil test to make sure the oil is in good shape. i use amsoil sso 0w30 and is one of the best oil on the market imo and with my used oil test proves i can go longer if i wanted. myself i still change it 3000 to 6000 miles.

going 10k on an oil change may not hurt you now but it will bite you in the ass in the long run. i use royal purple oil which is "advertised" to be good for 12k but i have never been over 3k on an oil change.

Maybe it will be fine, mmaybe it won't. But for the cost of oil, I dont see the point of pushing it past 4-5k miles.

OK. That is a long time to go without an oil change. However I did see a thread in here with a guy running his LS1 to 10k and oil change. However he sees 3k miles a month and all interstate. He did an oil analysis and it showed everything was good. Would I say you should do this. HELL NO!! Why would you want to not pay $50 to change the oil? Because once you spin a bearing its going to cost a lot more...

So basically what I'm saying is you drive a LS1 (pure assumption because your on the site), its a high performance engine and should be treated as such. Buying expensive oil and premium gas are part of it. If you can't afford to take care of it, go buy a honda element and change the oil every 10k miles.

Cheap PM...

i change mine every 3 but mines not a dd and everytime i drive it i give it hell id say a normal ls1 every 5 no more

I've used M1 Extended Performance which says it will last 15k. Now I changed it around 6k-7k and it always looked got. So could the oil last that long maybe but it isn't worth the risk.

My DD gets change every 3-5k depending on how it looks on the dipstick. The camaro gets it about every 1K or less bc I only drive it about 1500 miles a year, if that much. That being said, I couldnt sleep at night with 10k mile oil change intervals.

mine gets changed every 3-5k also, the oil I use says you can go 10k but Im not going to do that.

The concern to me is not that you aren't changing enough, but you run your car low enough for the low oil light to come on. Check your fluids man! I don't agree with 10,000 mile oil changes, but dirty oil is better than no oil.

ditto, plus don't just stick a quart in and wait for the light to go off... pull the damn dipstick out and check it.

i use Mobil 1 & change it every 2-3 k

No offense,
but a manager at Jiffy-Screw is not the person that I would be taking advise from when it comes to my car.

"Euro-trash"?

thanks for letting me know that those are just Euro-trash

Nope, not Jiffy Lube. And I'm telling you "how" places like that rip you off-I'm trying to help you dumb ass.

Oh, and I suppose you think that other places are better than others when it comes to service centers? Wrong pal, they're all there to take your money and that's the truth of it.

As for Euro-trash, it's a joke man, loosen up a little. You'll have a heart attack if you take things too seriously.

Bottom line is, it doesn't matter what kind of car you drive-10K is too long for an oil change interval...

... how long are oil filters DESIGNED to last?

i know fram has that x2 filter that is supposed to last up to 7,000 miles (most likely the only research and development involved was from within fram's marketing and legal departments), but what are the 10,000 mile guys using?

Sh*t, you mean I have to change the filter too?

I do mine at 2500 miles, good insurance for very little cost. It also gives you a chance to give the car and engine a good look over, assuming you are doing the oil change yourself. And you are, right?

With all the oil these freakin things burn you should never need to change it, just keep putting a quart in every 3K and it'll always be fresh.

haha nice.

I've been changing it every 5-6k on a synthetic oil. Oil isnt that expensive so I don't see any reason to push it any further. It really depends how you drive. I drag my car like twice a year so I dont see the need to be changing the oil every 3k. If I start driving my car more aggresively i'll go to 3k changes.

I have a buddy who bought a brand new Corvette in 2000 and the video that came with it that showed how to work everything said to change the oil every 12 months or 12,000 miles! When we were watching it we both looked at each other thinking we heard it wrong, so apparently even GM thinks it's ok. But I personally wouldn't do it in any car I cared about, my winter beater, well that's another story. :secret2:

I will, haven't done this yet, change the oil on the trans am every 3k miles or every year with good stuff. My landcruiser on the other hand gets a change every 5k or twice a year-- with the oreilly crap. I keep it right on the dot. Oil is the blood of an engine. Clean it and don't deprive it.

Gm wants your ass in the shop!

Just an FYI for you guys that think oil changes are too expensive. I swung by Autozone to pick up some Penzoil Platinum, and they had a really good deal. You could get 5 quarts of Penzoil Platinum, with an M1 oil filter for $28. I think it ended up being $37 with an extra quart, and taxes.

So instead until you hit the 10k mark, go get some of this stuff.

I had a story told to me by a friend, that his Father actually thought like this and burned up a motor is his Chevy truck back in the 70's.

Figuring, hey that's a 350 with 4 bolt mains lets see if we can use it. My friend & his son pulled off a valve cover to find so much sludge that a screwdriver stood upright in it for hours until the Grandad go home to see it.

3K is over kill imo, there have been a few threads on various boards where a guy has sent his oil in to be analyzed and everytime came back that it would have been fine to run longer. granted 10K is WAYYYYYYY past due, even if it is ALL hiway.
i run mine for around 5K, be kind to the motor and you'll be ok with 5K.

most of us are not kind to our motors. if you can only do one thing for the car, that would be frequent oil changes. yall should be horse-whipped for leaving that shit in there for over 3,000 miles. what are you driving, a friggin diesel truck?

i use castrol syntec and chane every10K to 12K and the oil still looks good i keep a good check on it though filter is very important though i wouldn't use a cheap filter and do that

i ran amsoil for one year 34K miles no issues in a tahoe it ran better got better MPG and everything it was series 2000 0W-30

i change mine at 3k. i'd never consider going close to 10k but if you did i would at the very least change the filter at 5k.

Why would you? I probably change it every 2-3k miles(maybe less seeing the car is strictly a nice weather car). You can get a jug of full syn. at walmart for around 20 bucks and a Gm filter for 4 so why milk the change out til 10k miles.

My z28 gets it's oil changed every 1500 miles since it sits 95% of the time.

My POS DD gets a oil change every 10-15k. . . . Yeah, I know that's bad. But, the motor is on the way out.

If you somewhat like your car and want the engine to last. Never go longer then 5k. IMO

I would like to think you are kidding but I don't think you are. 34k miles on one oil change is wrong. You might as well of just ran water in it. Sure it ran now but you just shortened the life of the motor by 30k miles. You are an idiot.

i change mine every 3,000 miles,i wouldnt push it any further if you plan on making your LS1 last..

My DD gets change every 3-5k depending on how it looks on the dipstick. The camaro gets it about every 1K or less bc I only drive it about 1500 miles a year, if that much. That being said, I couldnt sleep at night with 10k mile oil change intervals.

Exactly. Words straight from my mouth.

thank you but amsoil who i say knows way more than you says its ok and my 2002 tahoe that gets 24mpg with 22s and runs flawlessly with now 160K+ miles on it says your not so smart yourself and the techs at amsoil are. I must say it was a gamble i was hoping it would ruin the motor so i would have a good reason to put a 402 in it but in fact its running now as good as ever on its 3rd one year interval change the year after the 34K it went 29.5K and this year its looking like another 30+K...

main thing is to keep a good filter and check the oil if its brokin down change it i never let my oil get brokin down if you change your oil earlier than 5K your wasting money but the good thing is its your money to waste.

for you folks waisting money changing your oil and hurting the environment with the extra waiste every 3K .... i would like to let everyone know i change my G8 every 10K it was changed a 500 miles 2000 miles 10000miles and 20000 miles and it just dynoed 335rwhp and 353tq with just CAI thats up there with the highest CAI G8 numbers and it had 25000 miles on it on the dyno the oil was 5000 young while it was on the dyno at 30000 miles i will change it to amsoil sig series and i will not change the oil again untill 60000 miles unless a oil sample says i need to before then....

really what i don't understand is why people would waste money like changing oil every less than 5K ??? i mean are yall the kind of people that drink half a drink and poor the rest out or eat half a burger and throw it away to eat half of a different one cause your still hungry

i wish i had money to throw away like that

I run amsoil in my truck and change it every 7,500. I believe amsoil states you can run it as long as a year or 20,000 miles.

In my camaro on the other hand i use kendall and change it about every 1000.. but mostly cuz I'm constantly doing something to it

I go 10,000 mile in my peterbilt with a 425hp caterpillar,

Used Amsoil sig series 0w30 and run it for 5000 miles, could run it longer because the oil samples say so. but just change it with the filter.

No offense,
but a manager at Jiffy-Screw is not the person that I would be taking advise from when it comes to my car.


although i would agree most of the time, i also think that for all we know there could be some "jiffy lube" managers that have a ton of experience with cars and just got into for some reason like they know the owner or got hooked up with decent pay.

jmo

i change mine every 3k but also get free oil changes :D

depends on the series oil i def sample it and change filters :) just sturing things up :) i noticed things had slowed up and i have nothing else to do

...place I did my oil change at said I can go 10,000 miles between oil changes?

Is that same person going to buy you a new motor? Mobil1 is junk. Use Royal Purple. If you can't afford it then use Castrol.

Amsoil from all the tests I have seen conducted CAN last 10k+ miles no problem, but Amsoil is expensive. I usually change mine between 4500-6000 miles using RP... I wouldn't feel comfortable running it longer then that but that every 3000 miles scam was made up back in the day to help boost oil sales and was largely based on conventional oil that had none of the modern day detergents. Even conventional oil these days should be good for 4500 miles in a daily driver type car... Of course I run the synthetic as an added protection that my oil can last 4500+miles....but ya that's my .02 anyways.

Really?! pour...waste..broken..not that difficult.
Now for the highlighted sentences. You are bashing people for "wasting" money on frequent oil changes, but you, yourself, just posted you tried to purposely blow an engine. That's not wasting money? Also by stating such you have essentially agreed that going too long between oil changes is detrimental to an engine. Or at least that was your thoughts too.

I run amsoil in everything of mine.. I change the oil on my LS1 about every 8k miles, I just add a quart in between when needed.

change mine every 2500-3000 or 3 months oil still breaks down over time even if the car isnt driven

theres nouthing wrong with 3 k or sooner oil changes the only reason companys said 10k is that we hurting the enviroment with to me is stupid crude oil came from the ground whats wrong with it going back plus the oil never wears out its the addtitives that do so to me change ur oil when ever u want hell i have a friend with a yfz that he ride the piss outa it every day and he never change the oil since he bought it brand new and he never had problems with it so with oil its kinda what ever u wanna do 3k changes 10k or never its ur choise if u think its expensive to do 3k changes and try to push ur motors u should try to pay for a diesel oil change my dmax holds 10qt and i run amsoil everything in all my trucks so its over 100 bucks with a filter every 5k but i do it sooner if i towed anything (yay ramdom rants)

There is some good info here about oil change intervals, etc.

If you use a quality synthetic oil and a quality oil filter you could go 10k miles. Topping off is a big part of keeping that 10k mile interval going. Your oil should be one with a high TBN to start with, as well. If you have doubts as to whether what you are doing is smart for you, have an oil analysis done at the end of the interval to see what is going on in your motor.

Modern oils have come a long way in the last decade and you really have to look hard to find a BAD oil. For that reason, the only people that might come out ahead by using synthetic oil over long intervals would be those that rack up huge miles and 3k mile intervals would be every other week or two.

The LS1 is a quality engine and is not so delicate as some would think. What kills me is the folks that go on about the engine being from the right hand of G@d in one breath, and in the very next breath would say it needs extra care and pampering.

In the end, do what you will. It's your money.

. What kills me is the folks that go on about the engine being from the right hand of G@d in one breath, and in the very next breath would say it needs extra care and pampering.



i would pamper anything given to me by God, then sell it on ebay.

It amazes me how much this subject gets beat to death. I use to have a customer at the Honda dealer I worked for that always wanted samples of his Amsoil and wanted to know how the oil "looked". It looked like dirty old oil!
I've had plenty of engines and seen plenty more that went 5k-10k or more on oil changes all the time and went over 200,000 miles. I've also seen engines spin bearings at 70k miles from a lack of maintenance. It's cheap insurance to change it often. And bad for the environment to change it at 3k?:eyes: Give me a break. Oil is recyclable, and if you're THAT worried about the environment ride a bike. We have bigger problems than too much used oil being recycled.

Personally, I use regular oil and change it around 3k. Water condenses in oil and makes sludge, blow by gasses contaminate it, it breaks down over time, etc.

Mobil 1 and a Wix filter in my 02 Tahoe every 7,500 miles, comes out just as gold as when it goes in. My 01 SS gets Amsoil and a Wix filter about once a year which usually has went less than 2,000 miles.

STREETRACEGUY... 34K miles is too long even though your using Amsoil, and I know they guarantee 25k mile oil changes, but thats crazy.

every 5-7k in the daily driver with Royal Purple and a Wix oil filter.

unless you are a idiot you wouldn't wait to 10k to change your oil. no matter what it says or people tell you, you be the judge. depending on color and consistency you can judge if its time to change due to thermal break down.

change it every 2k to 3k. you can go more but like previous people said i wouldn't push it unless you want to buy a new engine.

^^^ There are thousands of oil test that prove that the oil is in go shape and the addive package in the oil is there doing its job for longer then 10000 miles. Idiot or A someone saving money and still maintaining proper lubercation and maintence to there engine, YOU BE THE JUDGE.

Mobil1 is junk.
You might want to tell that to my 190k mile strong-running car, it apparently didn't get the memo.

2k-3k is like brushing your teeth 11 times a day, really not neccessary at all. Especially if you're using a good synthetic.

Read this forum, it has oil analysis test results from a variety of cars with a variety of oils at a variety of change intervals. Some of you may be surprised at how good used oil can look at extended change intervals.

I think if the oil is has some miles it should be dark looking that means to me the oil is captureing dirt and suspending it, or that my motor is clean for the oil having badass deterengets and is also doing its job.

I wanna see the guy running 30k oil changes go up to 100k, then we can see screw drivers stand upright in his heads when he pulls em off!! All kidding aside, an oil analysis is the best way to tell oil condition, as for me, I'll stay over anal about my oil changes(3-5k miles):engarde:

no do not be a cheap ass and buy that bullshit. buy the good stuff and change ur oil every 3000 miles. oil is your cheapest insurance

Lol. Only in America is it accepted practice for people to spend extra money on synthetic oil and still change it every 3,000 miles.

x2 to both of you. Anyone that's done any research at all would know that changing synthetic oil every 3,000 miles is a waste of money...nothing more. You're essentially wasting perfectly good oil.

Yes i agree.

People i know where going nuts when i told them that i change my oil sometime after 5k miles of use.

every 6-7K on the camaro, every 11-13K on my Oldsmobile. Amsoil in both. XL in the camaro, extended life (12 month, 25K miles) in the Olds.

Yes i agree.

People i know where going nuts when i told them that i change my oil sometime after 5k miles of use.

Yup. I've always done every ~5k for synthetic changes.

on the v6, i change it when the lifters start to make noise, usually around 3-4k lol.

That probably has more to do with the level of oil getting low than it does the oil requiring a change. It doesn't take much of an oil level drop in some cars to notice that type of sound.

Oil "breaking down" is more of a by-product of contamination and not actual wear to the oil. Without contamination synthetic oil would last a very long time. In F100, 200, 220 and 229 turbo-fan engines, there were only a couple reasons to change the oil, scheduled maintenence, unscheduled maintenence or when I directed it.
I performed spectrometric oil analysis for 14 years and ran the busiest lab in the Air Force for 7 years. These engines could go their whole life without ever changing the oil (they are typically running at 11,000rpm most of the time). Not bad for something so critical that a 2-4 PPM increase in a wear metal was reason to ground the aircraft and investigate the cause.
In a car, the additives in the oil will get used up and the oil will get contaminated from combustion chamber blow-by. Who is telling you to change the oil every 3,000 miles? The filter can be changed every 3,000 miles, the oil every 6,000 and you still are not taking the synthetic oil to it's limits. And remember, oil darkening is from carbon, not wear, and oil does not start out an amber color, that is from additives.

I was told that all LS1s came lubricated from the factory as a sealed unit, and that i wouldn't ever have to change the oil for the lifetime of the vehicle. So far i've made it to 116XXX miles ;)

... ok ok... i'm kidding. I wanted to comment, but not just reiterate everything that's already been said.

I change my oil in my Tahoe with Mobil 1 every 5k miles and my SS every 2k Molbil 1 of course. I only drive it on good days no rain,snow or winters, EVER.

That probably has more to do with the level of oil getting low than it does the oil requiring a change. It doesn't take much of an oil level drop in some cars to notice that type of sound.

nope. oil level stays relatively constant. i make sure of that. i think the oil just starts breaking down. regardless of which oil i use, lifters will start tapping at around 3-5k. probably could use new ones... but i'll get to that when it becomes a constant noise. i just use bullshit oil now. whatever is on sale at autozone lol. it's a v6, i'm not worried.

That is interesting. I can't say that I've had that happen with any of my vehicles in the past.

Lol. :D

just ran castrol syntec for 10000 miles and the oilanalizer lab results came back great they recommended i run it 7000 more miles then send another sample

however i went ahead and swapped to amsoil so i can get 25K plus out of this oil change if the samples keep coming back correct

bottom line still stands that changing every 3K is just plain waistfull unless it takes a year to get that 3K lol or its a straight race car but daily driver it is just waistfull

After 4-5k my oil always comes out pretty dark colored. Maybe it is still OK, but without sending it in I won't know. It just looks eehhh... so I change it. This is with mobil 1 and mostly highway miles.

we all beat the shit out of our cars or atleast most of us do maybe in ur dd you can let the oil go that long but not on a car that is brought up to 6000 rpms everyday i dont dd my trans am but when i dive it i give her hell so i change mine every 3-4k which is like 2 oil changes a year

4 oil changes on a DD saturn ion redline... 57000 miles, and i beat the piss out of it....

10 oil changes on a 2001 s-10 4.3l 150k miles driven hard and put away wet ... runs like a sowing machine.

i change every season in my LS1.... or about 5000 miles....

AMSOIL FTW

Oil is cheaper than metal... Thats all that needs to be said.

There are two things to know about oil.

1. Keep it changed

2. Keep it changed

I run the cheap stuff in my car, but change the oil every 2500-3000 of street driving, or after about 10 passes. All the marketing/hype/technology in the world can't beat changing oil often.

I dont put many miles on the car but ill change it every couple mths...IMO my cars to important to me to try to save a buck by stretching out oil changes. Its the cars life blood :)

I wouldn't run standard parts store oil and filter that long, but I would if I were running Amsoil with a sub-micron filter setup.

I usually go about 4k or so in the Bird before oil changes (running Penzoil Platinum 10-30), and about 6-7k in my Jeep 4.0 (WalMart SuperTech 10-30).

The general rule of thumb I use with the Bird is I just change it when the oil gets low. I'll add the 1/2 quart I have left after a oil change the first time I check it and it's low, then when it's low again I'll change it.
