what ive been told on here is that the ester based oils (redline) will break down faster than full syth dino oil. so yes the redline might be better but only while its brand new.
i was changing my redline at 4/5k miles and the oil looked HORRIBLE!!!! i was told thats too long of an interval for ester based oils.
i now change my mobil-1 full snth every 4k miles and im all gravy.
