Best Oil?

For a stock LS1. Completely stock. I've always used Lucas Oil, but I just switched to Royal Purple. It seems to run smoother now, althogh people are telling me to switch to Pennzoil Platinum.

What do you think?

PP 10w30.

157k. All the way

Royal Purple is one of the worst....

why is royal purple one of the worst? Ive been using it for about a year in my 98 ss with 100k. Im just curious what your reasons are for why its so bad?
its been dyno proven to give you extra horsepower and extensively tested to be safe.

Yeah I've heard a lot of people say that Royal Purple isn't very good without saying why. My old automotive teacher from high school swore by Royal Purple, and he was an intelligent man with a bunch of car projects.

I'll give PP a shot in about 3000 miles.

Ive used the walmart syntec brand in everything I have for the past ten years,oil comes from the ground,any name brand oil should do, keep it changed and a good filter..$.002

So my conclusion. The best oil to use in a stock LS is either Royal Purple, Mobil 1, Pennzoil Platinum, OR Walmart Synthetic Brand. Haha, I guess I'll just keep doing what I've been doing. :sillyme:

SuperTech/Walmart full syn = 1 1/2 quarts consumed between oil changes
Valvoline Full Synthetic = 1 1/2 quarts consumed between oil changes
Royal Purple = Maybe 1/4 - 1/2 quart between oil changes
I am thinking about trying Amsoil on my next oil change.

Bullshit.
Read it all...when you come out the other side you will piss in Royal Purple jugs and see the improvement. You will also be able to differentiate based on fact and not butt dyno nor marketing crap.
