edit - yes if you pay more you'll get better quality oils, but i think a "lower quality" like a T6, pennzoil, mobil, will do a good enough job in a 3k-5k OCI condition or in a couple of race events, that most of us would never see the true benefits of a more expensive oil. although, i'm guessing the higher priced amsoil offers some kind of insurance if you lose oil pressure all of a sudden. because of its chemistry and bond, it allows the engine to perhaps run longer with no oil pressure than say a T6 or pennzoil or mobil1.

AMSoil has their own compromise in oils to be honest. They have the multiple lines of Oils for different prices. $15 a QT is crazy expensive but doing quick math, If I had to change my oil once a year opposed to 2-3 times, I am already saving money! This is all factored in on miles you drive each year, I maybe get 10k in a year if I am lucky. I use T6 in my WRX so going to the Boosted series, which would still last me 1 year would be cheaper and one less oil change.
To me this doesn't matter, just food for thought. I don't think i'll switch my WRX to AMSoil but I know my RB is going to run it once I get it going.
He showed me the 3 common kinds. Signature series/Boosted/OE. I think the prices were $15/10/7(This might have been dealer price? I am not sure) don't quote me but it's close!
EDIT:TheRealSy90. I agree with the 0/40 being useless. I ran 0/30 in my RB for about 8 miles until I changed it out due to having no ZINC whatsoever, my lifters were ticking like crazy. After my rebuild I am seeing like 9bar psi at WOT so was testing lighter oil to see if it would help lower my pressure. Im not sure when or if too much oil pressure can cause issues.
