People often ask me about engine oiland the bottom line is that there is no way to know without a whole lot of data and research. I personally don’t have a problem with the synthetic.

I Changed my oiil this weekend and went with a penzoil synthetic blend . I have a 4runner SUV and it calls for Synethic.

Seems to run great on the synthetic. It is quiet and the temp never gets up, so it must be doing the job. I’m looking for some thoughts that anyone else has on the subject. Especially anyone running a turbocharger and their thoughts.
