99 Ram 1500

[hisilver]

Hello all, first off thanks for a great site. Been a long time oil freak too!

I have a 99 ram 1500 5.9L. 125000 miles. Before i owned it, the previous owner, my friend, said he got work done to it (valve seals?) because of oil consumption of about 1 qt. a week. Now after repairs it still drinks about 1 qt every 3K miles. Sometimes more. It has almost always been low on oil and it towed and worked before i had it. Always got cheap oil and filters from quick lube places with unknown OCIs.
I would like to know if i should go with Mobil 1 High Mileage or Valvoline MaxLife Synthetic Blend Both in 10w30. Would like to run Valvoline MaxLife Full Synthetic but CANNOT find it locally. thanks.

Another to consider is Pennzoil High Mileage.

Maxlife Blend is a great oil, and will do really good.

Coming into spring/summer, I'd try the 10W-40 grade.

1 qt every 3k miles is not surprising: first, its not an extremely close tolerance engine second: its service history is dubious. good this is that the Magnum engines can be very very durable, as long as the oil pickup screen doesn't clog with sludge

what about the intake plenum? those can cause oil burning. mike
