sorry if this is a repost or whatever but wha's a good brand or whatever of motor oil13b n/a if your askin all stock also....an stuff that i can get at like autozone or pepboys because i dont really want 2 wait buyin it from the internet

 

a lot of people reccomend castrol gtx. im using gtx high mileage right now. and dont get synthetic.

 

You know what? I want to try heavy duty synthetic diesel oil in my car. Diesel's blow black smoke because they burn the oil, and my friend's dad who has been working with motorcycles and ****, recommend that my friend run synth 15w40 diesel oil in his 240.



BTW, this oil is recommended for heavy applications that run superchargers, turbochargers or have alot of horsepower.

 

what is the advantage of that?

 

UMMMMM NO



That oil doesn't burn very clean for all you stock MOP running guys!!!

 

Hence the "thinking" part.



I run 20w50 non synth in the 7.

 

Royal Purple is a synthetic that can be burned just like two stroke oil.

 

i think reted said he once used rotella in a rotary.

 

rotella?

 

Shell Rotella



Chevron Delo



Popular diesel motor oils. I would really like to hear what RETed has to say about it if he did it, but I wouldn't trust it to burn on a stock MOP. Diesels don't really burn that much oil on purpose.
