I've been using Mobil 1 Syn in my coupe. Dealership just switched from Mobil 1 to Kendal Syn, so I've been buying my own Mobil 1 and taking it to the dealership. Is it ok to switch brands? Does anyone know if Kendal Syn is a good oil?

 

according to the owner's manual you can use any oil that has that approval seal on the bottle.

If you read the mobile 1 bottle, it says that it is compatible with all other oils.

Actually Kendal is rated really good. I heard even better than M1. It will not hurt to switch between synthetics.
