Royal Purple. Engine Damage In The Long Term?

Methodical4u · 08-15-2011, 04:36 PM

these engines get so hot that even Mobil 1 supposedly breaks down very quickly. I know of some engine builders who have torn down motors and found damaged internals due to lack of proper lubrication from some who were using RP... now does that mean that it's true and that it's not a good oil? No it doesn't, but it's enough that I won't use it. I use AMSoil SS0 0w30 and I get EXCELLENT gas mileage, the engine is more quiet and it feels like it has a bit more zip. It also is claimed to be able to go 25k miles or 1 year for non performance cars that are not driven hard.... my mother had it in her car for a year and I changed the oil and it still looked, felt slick and smelled fresh. It's all I will EVER use.
