I've finally used up my stash of PZ Ultra 5W30 (SN version) which I acquired at the local Wally Worlds in the area a couple of years ago (been using it in both the van and the car). At 128,000 miles the minivan has developed a slight drip on the rear oil seal (not much but a couple of spots on the driveway after a couple days). I'm going to switch it over to a high mileage oil and have narrowed my choices down to either Mobil 1 HM or Maxlife Synthetic (both available at WM...less than a dollar difference in price).
I used the Mobil 1 HM in my 'ol PT Cruiser for a couple of years and liked it...not familiar with the Maxlife. I see that the Mobil 1 HM (5W30 version) is still SL rated (due to phosphorus and zinc levels?) and the Maxlife is SN. The Maxlife also appears to have more spec approvals (due to it's SN rating?). Granted it's an old van and it may make little difference but just wanted to get opinions here regarding these two oils. Winter temps here are subzero for days on end so I'm not interested in conventional HM oils as I want the better flow properties of the synthetics.
The van is due for a change next week...appreciate any input.
