Mobil 1 10w30 oil, use it or take it back?
I bought 6 qt's of synthetic 10w30 today. After I got home I did a search on what the rest of the board uses in their cars and I'm not so sure I want to put this in my car now. Should I take it back and get the 5w30? I don't beat the car too hard and it's mostly a weekend warrior for now.
I just bought the car not long ago and the guy I bought it from said he used mobil 1 synthetic, this is the first oil change so I'd just like to be extra careful.
thanks.

i'd never run a mobil 1 30 weight in my car even if it was free. it may as well be a 20 weight. it's too thin for an LS1. i'd take it back for MADE IN GERMANY castrol syntec 0W-30 at autozone. it's thicker than both those oils. it has the startup protection of a 0 weight which gets to all the vital parts as quickly as possible while the 30 weight is a near 40 weight at warm temperatures.
if you can't get GC 0W-30 i'd get mobil 1 0W-40...but GC is still far superior.

No problem at all using M1 10W30. That's all I ever use.
Contrary to popular beleif around here, M1 5W30 and 10W30 won't do any harm to your LS1. The motor will still run well past 100K miles with proper maintenance, even using the "dreaded" ( ) M1 5 or 10W30 oils.
Beleive it or not, you don't even need to use synthetic for the motor to last!! Yes, I said it, conventional oil will not kill your motor! Of course synthetic is better, but it's not requried.
If you want to go with the other oils menetion on this board, that would be fine too. But don't let people convince you that M1 will kill your motor. That's just silly.

I honestly don't beleive that using M1 10W30 is going to cause any issues. I'm sure the motor will live a long and happy life.
There might be other options that look better on paper, but what does it really translate into in terms of engine life? Is it significant enough to really worry about hunting down one specific oil? IMO, probably not. Especially consdiering that the M1 5/10W30 is already better than the conventional oil that our LS1 F-bodies came with from the factory.
I'm not arguing that something out there is better than M1 (I'm sure there is), all I'm saying is, when does it become overkill?

mobil 1 5W-30 and 10W-30 are not bad oils. however, they're not an optimal oil in the LS1. your wear numbers will be much higher with them than if you use GC 0W-30, or even mobil 1 0W-40.
your engine will like you a lot better for using GC 0W-30.

i had a slight rear main seal leak and i switched to mobil 1 10w30 and it's now leaking more. before it was just a little wet, now there are pretty good sized oil spots on my driveway.

i have used castrol 5w30 high mileage since its kind of too late for me to switch to synthetic (I have 81k miles), and my motor has always had 5w30 of some brand (usually pennzoil i believe) and doesn't burn a drop, so far. It ticks like a bitch, but thats normal.

My '98 has had nothing but M1 5/10W30 since the factory oil was removed. 8 years; it burns no oil, it leaks no oil.
Having said that, I may try the M1 0W40 one of these days, just for fun. Never let it be said that I'm not willing to try new things.

Next thing you're going to tell me is that E10 fuel will destroy all our fuel systems in short order. Once again, 8 years, no problems.
Honestly, I beleive that you overreact to things.

Good for you.

E10 cuts fuel economy. it's a fact. get over it. i never said it'll break your car, although it will do more harm than good.
get over yourself. just because you buy into marketing doesn't make you correct. there's a reason why mobil 1 is the number 1 synthetic oil. it ain't because it's the best oil in the world.

What personal experiance do you have with engine logevity using M1 10W30 vs anything else? How many LS1s have you blown up on M1 oil? How many LS1s have you owned period? And how long? And at what mod/power level?
Again, no arguement that the GC 0W30 might well produce better wear numbers. But personally, like many of us, I've never owned the same car for 200K miles, so I really could care less if it dies at 200K vs 230K. It's just not enough of an impact to make a difference during the average person's ownership term. Therefore I can't justify running all over the area looking for one specific oil.
I could see myself trying the M1 0W40, assuing it's not going to take forever to find.
Point is, you tend to overreact and lead people to beleive that things are much worse than they actually are. Just relax a little.

again, experience is absolutely useless - unless you can turn back time. you can't run your engine with mobil 1 til it breaks, then turn back time and use a different oil to see how it compares. the ONLY thing you can do is read oil analysis tests which shows how much wear an engine undergoes during an oil cycle. guess what, mobil 1 wears double that german castrol wears. this means mobil 1 is taking that much more life off your engine every oil change as opposed to you using a different oil. you want to be stubborn and buy into marketing hype and believe just because it hasn't broken, it means it's the best, go ahead, more german castrol for me. just remember, however long your engine lasts, you coulda went longer. you apparently haven't read oil analysis tests. i have, making all your "experience" inherently useless since experience doesn't dictate how long your engine lasts.
check out bobistheoilguy.com. see for yourself. all the "experience" in the world cannot make up for real testing.

as you can see, everything is well below average and he is actually recommended to run the oil longer next time since it's still like new after 3,000 miles. if you cannot find GC 0W-30 at a local autozone, on page on of this thread, i posted a website you can order it from.
