The most commonly argued topic concerning engines of all time.

What kind of motor oil do you use and prefer?

ALSO POST UP WHAT WEIGHT OIL YOU USE!

Currently using NAPA brand dino oil, but I will convert to synthetic when money allows for $50 vs $15 oil changes.

Royal purple is GREAT...if your willing to take care of those leaks that develop.

Just plain old Castrol 10-30 with a splash of Hyper Lube and a Mopar brand filter.

I have 130K+ and see no reason to run anything else.

i use Mobil 1 Synthetic 10W30 Extended Performace, and replac a quart with Lucus Synthetic Oil Stabilizer, and use a Mobil 1 Filter. Ive used many oils, and this by far is the best. Ive taken a class on Mobil 1 oil, so iknow the benifits. This oil Cleans out the motor of sludge as well.

i use mobil 1 awesome oil too keep that motor turning

Valvoline Durablend synthetic blend 10W-40, seems to work good

Castrol gtx 10w30 also with a napa gold wix fliter

i clicked the 4x4 oil because its quaker state but i actually run quaker state horsepower 10w30.

I generally run Mobil 1 10w-30 fully synthetic with 1 quart being the lucas oil stabilzer. Recently I have switched over to Valvoline high mileage synthetic blend 10w-40.
