Trouble with Grand

[jeepit]

Had seal replaced behind timing chain cause anti freeze was leaking out big time on 97 Grand Cherokee. Oil change was needed since some anti freeze may have gotten into oil. I have run synthetic in it for 100,000 miles and now shop put in dino oil. Do I just run it like this? or do I change it out and put synthetic back in immediately??

Any imput at all?

Synthetics are compatable with dino oil. Should not be any problem what ever you run. Most synthetics are made with canola oil. The additives vary so the package is changed when you change some brands. Deisel has addatives for soot suspension in them that gasser oils don't have.
