I prefer Pennzoil Platinum. The oil analysis results are showing this oil to be an extremely consistent performer, and it's been on sale quite a lot over the past year for some killer deals (such as 99 cents/qt after rebate!)

I use exactly what GM tells me to use: Mobile 1, 5W-30.

However, I'm sure that the other brand-name synthetics are just s good.

Not that many people use Amsoil. I think it's because it's not that common and it's pretty pricey. I have a dealer account with them so I use it in all my vehicles. I wish you were closer, I always sell to my friends at cost + tax.

Mobil 1 as used by G.M. !

Mobil 1; buy the 5 qt jug at Walmart.

jrose7004 · 05-30-07, 08:47 PM

Mobil 1 always.

I've used Pennzoil Platinum, but I'm trying Royal Purple. I 'm not a fan of Mobil products, and Platinum meets the same GM spec at Mobil 1, and it's cheaper. I just put in the Royal Purple, so we'll see how that works out.

Only Mobil 1 for my beauty!!

Pennzoil Platinum. Meets GM spec 4781M and has always been good to me at a price $8 or so less than M1 in the 5 quart jug.

Just so everyone knows, Pennziol Platinum is made by Shell Oil Products U. S.
Shell also makes "Quakerstate Q Advance" Both are synthetic, both meet the GM4713 spec.
There is some special additive technology in the "Q" Advance" that reduces friction by a large amount when it is @ operating temperatures. This will give more power as less is lost due to friction.

It's ok if you don't believe me, I'm just you friendly neighborhood tribologist...

I'm sure that Quaker State's new synthetic is good enough to pass the GM4718M test, however according to their spec sheet it does not list it as meeting this spec. So one should be careful about using this oil in a new Corvette under warranty. Pennzoil Platinum not only meets this spec, but it's also on GM's registered list for 4718M as well:
