Im looking at another car (second car), and If I go pick it up, I want to know if its running synthetic oil or if its still dyno. I forget how to tell what they look like on the *** end of things. Anyone have any insight on that?

 

What???[sm=dontgetit.gif]

 

how do you tell the diffrence btwn synthetic and regular oil after you drain it if you dont know what it was when it was put in?

 

by taste! Synthetic goes down smoother.

 

U can not tell by looking at oils if they are synthetic or not ,to know for sure change them all out
