The oil question..
The oil question.. I know this topic has been touched on before, but I cant make up my mind on what oil to run in my 99 Z28 that I just picked up. The previous owner had been running synthetic blend with good results. Im trying to decide If I should go to mobil 1 synthetic, or what I should use. Any imput would be great.

Search, you might just be being lazy, HOWEVER to be fair there have been times when I needed info fast and did not have time to sit and read through forums so in my research for my 98 TA I have found that Mobil 1 Fully Synthetic 5-w30 is the best, doesnt thin out too much like Purple Royal, but to each his own. Good Luck

yep, get the moblie 1. they had a poll on here awhile back about motor oil and moblie 1 i believe was in the lead, then came that german 0w30 stuff. im switching to moblie on my first oil change (just got the car a month ago).

It's not that M1 is bad, just that the 30 might be a little thin. I've used the M1 Truck & SUV 5w-40 (now marketed as Turbo Diesel) and GC 0w-30 (now marketed as European Formula). Both very good oils, no noise or oil use with either one.

These guys have pointed you in the right direction. 0w40 is what I am currently using. Once I confirm that the 5w40 is still the same formula as before, only labeled differently, I will go back to using it. Either one is a good choice outta the Mobil 1 line.

Simply put, if you have a stock LS1 you could run any 0w-30/5w-30/10w-30. You could use any 0w-40/5w-40/15w-40. They will all work and not kill your engine within 100k miles.
Cheap. Expensive. Yellow bottle. Green bottle. Silver bottle. Blue bottle. On sale. Not on sale. It don't matter if you change your oil at 3-4k miles.
If you beat it hard, buy one on the thicker side of 30w.
Any other discussion that doesn't include proof of effectiveness like an oil analysis result is just an opinion.
