Hey guys, same old story, just wondering what your thoughts are on oils for the FD.
Im firmly in the mineral camp, and i just bought this oil here


Would this oil be too thin to protect the engine? The car is mostly used on weekend nights for motorway cruises/pulls/racing etc so i guess you could say it gets a hard time.

I have been using cheap ol castol gtx 15w-40 for the last 8 years or so..same engine.
My theory is the thicker oil helps with fuel dilution. I buy a couple bottles at a time when its on special @ super cheap for $23-25 each

 

I use Shell Rotella 15W40 for diesels

 

I use 10w-30 or 10w-40

 

Protek 5-30
