I was watching some show. They had a brand new engine, looked like a small block v8 on an engine dyno. brand new regular oil and brand new oil filter. made xxx amount of hp and tq. Well, they changed the oil filter, and put in Royal Purple, ran the engine at the SAME temp and speeds and gained around 11ft lbs of tq and 8-9 hp. Can just oil do that? and how? is it that much thinner? If its too thin isn't it getting too hot inside? I havent really read up on R.P. but i dont feel like spending 10 bucks on a qt of oil.

If my car ever becomes the garage queen then i'll think about it.
