5w20 Penzoil Platnium and Amsoil filter. Changed every 3k to 4k.

TINMAN080

10W30 Pennzoil Dino with the cheapest Fram filters, changed every 3000 miles faithfully. My last jeep I sold after 198,000 miles with this combination, no repairs on engine AT ALL....

Mobil 1 5w-20 and Motorcraft (Ford) FL-400S filter, every 4k, over kill yes, but it helps me sleep better

esantia

Mobil 1 5w-20 extended & mobil 1 filter change at 10,000.

Adam3612

Mobil 1 5w20 Synthetic and Napa Gold 1348 Filter

Penzoil 5w20 and Fram filters, every 3-4k. Starting to get a slight tick at start up, which many have resolved with Mopar filters (trying that in about 1k miles)

I know this is an old thread but I just tried to get my Oil changed this weekend at Jiffy Lube and they told me that the only Oil they had that meets the Mopar standard is a synthetic blend and full synthetic. Do you really need to run these or is just straight old 5w-20 ok to run in these motors???

Whichever meets the required specs and is the cheapest.

Mobil 1 synthetic 5w-20 and Motorcraft FL-400S filter every 5000 miles.
