    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?

    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.

    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.

    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.
