Ive been doing some searching and cant really get a straight answer. I know your not supposed to run synthetic oil in a Rotary but people say its safe to run Rotella T6. its a Heavy Duty Synthetic Diesel oil so I was kinda sketchy about using it in my car. any help would be great. thankyou

I rather stick with regular oil or synthetic oil rather than using diesel engine oil. In my case I use 10w-30 synthetic and premix with Protek.
