Ok, this isn't about what type of oil you run. Its about 5w30 Mobil 1 in vettes.
Our trucks and vettes are LSX engines. But why in the vette do they say it is mandatory to run Mobil 1?
Same roller valve train right? If that's the case, shouldn't we all be using Mobil1 or some other full synthetic?

I may be wrong but I think mobil 1 is recommended for our trucks too. I know that is all that mine has ever had in it.

2002 black Yukon SLT (the skinny sister)
1969 green Pontiac GTO (Layla, AKA the black sheep)

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

i can't run full synthetic cause by the time i got my truck it already had 85,xxx miles on it...so i run 50/50
i run 15/40 in my turbo truck... but when i run it in my DD trucks they make noise..... so now i just run 10/30 ..
15/50 Mobil1 here per my tuner. He knows a smidge about what works I guess.
5w30 Mobile 1 in my SSS since I've owned it.

5/50 Mobil 1 in the Camaro, and 10/40 on the truck.
I tried a few synthetic oils, same weight, always return to M1
The only guide I have for this decision is my engine oil temp gauge, Mobil 1 keeps it 20 degrees below the other synthetics on same conditions.
No wise guy, but if temp is lower, I assume, friction is lower, so will be wear out.
i switched to synthetic at 110k, no problems here at 150k...i have been using 0-30 mobil, its supposed to cover the 5-30 and 10-30 warrantys...i noticed a LOT less of the notorious gm chatter at cold starts with this oil over the standard 5-30 synthetic. I normally go 7500 miles on changes too, oil seems ok to me afterwards.
blown transmissions are about as useful as 97% of the guys on this forum
