I USE THE NEW VALVOLINE BLUE 15W40. I GOT IT AT ADVANCED AUTO PARTS. IT SEEMS TO RUN JUST FINE. BEFORE THAT OIL CAME OUT I WAS USING ROTELLA.

 

Amsoil in the motor and tranny. Soon to be using it in everything

 

Shell Rotella every 3000

 

Schaeffer 15/40 dino oil with moly,Schaeffer 80/90 synthetic in both axles, and 5/30 Mobil synthetic in my TC

 

Hey "NoProblem", got a joke for ya. (I see you're a Coors Man...)

Q: How are a couple having sex on a beach and a Coors Light similar?
A: They're both f'in' near water...

Oh, and I'm a strict believer in synthetic in newer engines. Old engines (i.e. my flathead V8...no way. I've got enough sweat stains in the driveway...)

 

Amsoil bumper to bumper. Extended oil changes coupled with the bypass has served me well.
