Stopped at Auto Zone to get filters and oil for mine and the wifes Bi-Fuel Contours. Grabbed Mobil I and didn't realize it till after I had changed it in both cars that it was their new "blended" which I'm assuming is dino and synthetic.
On regular Syn Mobile I I change it every 10k with no problems (I've been doing it all my life (47) on a wide range of vehicles with no problems so save the change interval speaches).
I'm wondering what a safe change interval is with this blend. Any ideas?
