my opinion: oil is oil is oil. other peoples opinion: OMG ROYAL PURPLE, THEY USE IT IN RACE CARS AND THEY HAVE COMMERCIALS.

seriously, i put relabeled junk store brand oil in my car and it ran like a top.

well unfortunately i do know for a fact working with racebikes and testing different oils on dynos just to sqeeze out every last bit of hp that certain oils are better than others. this is on very high compression motors. per my personal experience with dyno time on HIGH COMPRESSION RACEBIKES (13:1 for example) will yield .07 to .1 hp at the rear wheel and allows for a quicker revving motor. but once again this is on very high compression motors where every last bit of power is needed. i do infact use royal purple on my racebike, but i use non synthetic in everything else.

the biggest debate i found online was if you use non synthetic then the rings seat to a certain slipperyness (if thats even a word), then you add something more slippery then you get oil getting past the rings. i also drive roughly 1800 miles a month

Before I say another word just know I am a bit biased because I am sponsored by AMSOIL. I use AMSOIL in everything I own for a few different reasons. Manufacturers like schaefer, Royal purple and AMSOIL already have all of the friction modifiers and additives in them for each specific application. WARNING running higher viscosity race oil in your car is horrible for daily driving! a 20 w 50 race oil will not curculate to critical areas of your engine as it is supposed too and you will drastically shorten the life of your engine. I change the oil in my race quad every 2 races and the oil looks clean after I pull it out. However in my GP and truck I run AMSOILS filter and change the oil twice per year. I send it back to there lab, they test it and send me a report as to when I should change it. My truck has ran on it for well over 100000 and doesnt use a drop of oil and gets 20 mpg highway. The GP is still in its infancy because I havnt owned it long but I did a 1000 mile amsoil flush and the crap that came out of the motor from cheap oil was horrible but its clean as a pin after my third change in 10000 miles. So I beg to differ oil is not oil. Royal purple would deffinately be my second choice if was going to run anything else, so take that for what its worth.
