Relax there, buddy. I was just stating facts for the OP's consideration.

In no way, shape, or form am I saying that I had those problems solely because I was running Mobil 1.

All I am saying is that there was obviously some friction-related deficiency in my motor that caused the roller lifter to poop out on me. Therefore, I will not take the easy route anymore, and buy Mobil 1. Instead, I will spend the extra $10 and do a little searching to find the German Castrol, which is, very arguably, the best motor oil for an LSx.

if you have 150,000+ miles, you switch to mobile 1, and your engine blows, I highly doubt its the oil that screwed things up. Just coincidence most likely and your motor would have blown no matter what oil you threw in. Just my .02

First of all, I didn't switch... I've used it since I first got the car at low mileage.

Secondly, you're probably right, it probably wasn't the oil and it probably would have done the same thing no matter what kind of oil I used. But can you honestly say that the problem might not have taken longer to occur with a better oil?

I switched to GC, after doing a lot of reading and finding out that Mobil 1 just isn't the best anymore. I used to run it, because I thought it was the best. Obviously, I was wrong.

However, my post was as much a complement to M1 as anything else. It protected my motor through 170k miles of me beating the s**t out of it everyday.

You should really think about what you're reading before you assume. I never said that M1 was junk.

OK I haven't been about to find the German Castrol in my area. Would Castol Sytec be an ok choice? MAybe i just need to look more.

WS6 store has it, and Mike is a great guy to do business with.

I get it at Autozone most of the time, but sometimes they're out.

Well I am actually impressed that mobil 1 was in your car for 150,000 miles, kudos there. I wouldnt blame the breakdown on GC though. It's been proven to be better. Again, everyone has their own opinion about oils, but from all the testing done, mobil 1 5w-30 is NOT a good oil for our cars. Who knows, if you would have run GC in your engine from day one, it might still be in one piece. We'll never know, that's why you research the tested oils and choose the best.

^^ No, no, no... the problems occurred while running M1... I switched to GC afterwards. I'm installing a new motor tomorrow... and after breakin, it will never see a drop of anything but GC.

the best Oil i have ran is Royal Purple, If you change all fluids over to Royal Purple, i cant remember, but there is a gain if HP. I ran it in my 88 camaro. I had it in the engine, and the rear end. Didnt get to tranny, and now its sold.
Its cost more, but its worth it IMO, its either that or Mobil 1 which is what i ran before i did RP.

I've made 4 trips to Florida, 850 miles one way. Each trip I averaged 70 mph plus or minus a few tenths, except for one trip slowed by an accident north of Tampa. I always travel I-75 from Knoxville south to Punta Gorda.
I've been using around one qt. of Mobil 1 10W30 each way until the last trip when I switched back to Redline 10W30 and used less than 1/2 qt for the round trip plus extra mileage while there. While on the trip, I don't beat the motor, I might hit 6000 rpm a few times pulling out of a rest stop. I never noticed oil usage until I switch from Redline (first oil change when new) back to Mobil 1 for several years. I've stopped for gas and cranked the motor to have the low oil light come one and started carrying a spare quart of Mobil 1 next to the battery. I added a catch can a while back but it doesn't catch anything. I've gone through a qt of Mobile 1 leading my wife's Porsche club when it was her turn to host a drive, allot of 1st and 2nd gear 6000rpm in the tight mountain sections here, hence the catch can.

Cheers, Curt

did he buy the car new? if used how many miles on the car. and how many miles dose he drive the car, how cold or how hot is it were you live. get the point. i used mobil 1 in every car i owend and i never had problems . i tryed castrol sy oil no problem sound like the car may have one. not driving the car much will result in that and if it was used hell know how that person drove it and the oil he used in it. ect. some of my2c

I have been running Mobil 1 for the last 147,000 miles in my current car. I change the oil at 5,000 mile intervals. I typically use 1/2 quart every 5,000 miles. I have used nothing but Mobil 1 in these weights 10-30, 0-40, (I can't find it anymore around here) and for the last 3 oil changes I have used the high mileage 10-40. Oil consumption has stayed the same 1/2 quart every 5,000 since I got the car. I can't complane about Mobil 1. I have had the motor down with head swaps and cam swaps a couple of times and it looks great inside...The car gets driven hard regularly.

Same here, i run Mobil 1 10W30 HIGH MILEGE changing it every 3500 miles and it never burns oil and is always clean when i drop the plug....great oil in my opinion, I thought about swapping to Amsoil but haven't heard a lot about it.

amsoil has consistantly had better results vs leading synthetic oils in . oh, by the way,, ive never seen an amsoil commerical, i actually dont think they advertise by anything but word of mouth and maybe an occasional raceday banner (could be wrong, ive just never seen any advertising)

I use it, I started using super synthetic and then went back to regular stuff. once I am done I am just going to use store brand stuff from Walmart or Advance Auto.

I plan to seafoam every so often to keep things clean.

I catch a few drops every 100 miles or so in my catch can. as long as it doesnt go into the intake I am fine with it. I also did some mixing of a few quarts of 5w-30 and 10w-30 that seem to work fine as well. whatever I run I just dont want it to be too tick for those winter months.

i swear by mobil 1

Asmodeus

Mobil 1 5w30 has been proven to be the worst Mobil oil for our engines.

If you must have mobil 1, find the 0w40.

COD02SS

Royal Purple went into my C6 at 100 miles.

Jontall

I like Mobil 1 0W40 and feel it's the best oil money can buy. It's not a GF-4 oil so it's additive package is much better then Mobil 1 5W30. It's just a better all-round oil.

T/AWS6969

Hmmm... I must get him to switch. There is only 12000 miles on the vette and it really doesn't make sense that he is burning 2 qrts in 1500 miles. I think he better go with (from the sounds of it) the GC 0w30.
