I know, not another oil question, but i'm approaching 30k and have always used honda or mobil one.

Was thinking of switching over to rotella 5w-40 synthetic for smoother shifts.

So how many miles and what oil are you using?

 

I'm using the Rotella T6 now and I just turned 218k, but I've only been using the Rotella for the past 18k.... previous 195k was with Mobil 1. They're both great oils... can't really go wrong with either. My motor is still spotless inside and runs like a dream

 

Over 48k on GN4.

 

How does your trans shift with all those miles? I actually have seen your youtube video. awesome dude!
