Hi all. I have a 97 ram 1500 with a 3.9 magnum. It has 110,000 on the clock. I normally use Mobile 1 EP 5w30 but the price with rebate was too good to pass up on the Penzoil Platinum High Mileage 5w30.
I've only got 14 miles on the oil but have noticed significantly less pressure with the PP at idle. Anyone have an idea what is going on?
