I know that this stuff it not getting a lot of positive feedback, I've read it all. I have about 28 quarts of this Nissan Ester 5w30, and just wondered how it would be to run on normal 3k intervals on a normal (non-nissan) 4 cyl engine? I've used Edge, M1, and PP is currently in the car. How does this stuff compare for normal 3k intervals?
