For starters, Royal Purple isn't even a real oil company. Honestly, how much do you think they spend on R&D compared to some of the larger oil companies?

I'm very adamant about denouncing and defending various oils, but when I can recommend you 4 separate oils that I KNOW protect even beat-to-hell racing engines with huge bearing spinning design flaws well, you can trust I'm really not that biased and they are probably good oils.
