Castrol GTX 10w40 and Fram PH13
tried synthetic and didnt like it. Ran low oil pressure with it, and after going back to regular it oil it was back up normal.

I also run the PH13... but I run full synthetic Mobil 1 5W30 ... never had any problems with oil pressure. I will be switching to 10W40 at next change ~ just to see if there is any real difference. :smash:

I use the AC Delco PF35 filter on my zz4. This is the tall version that holds a little more oil. For oil I am running regular Mobil 10w-40. After I get about 3k on the motor I plan on switching to Mobil 1.
