I was running M 1 in diff and engine. I am switching them over to redline this weekend. We'll see if it makes any difference.

 

I'm sure that Redline is great oil but if it were me, I would have at least put a few k on the Mobil-1 then switched to something that I felt more comfortable with.
I use Mobil-1 and plan to continue for the life of the car.

 

I like amsoil. I use amsoil in the diff, amsoil in the tranny, royal purple for the motor oil, ate super blue racing brake fluid for the brakes and clutch.

I too use mobil 1 syn for the motor and plan to do so. Had used oil analysis done on it and am happy with the results.

 

I'm totally noob when it comes to oils..and I just dont have time to do all the research on the wolrd

Therefore I decided to go with Redline products since they receive alot of positive reviews.

Althought they're expensive compared to other brands... however I personally don't mind paying more for the peace of mind.
