can you bump up to a heavier oil?quote:

Sorry, ZmOz, but I don't know your "case history"...what kind of vehicle and what is the cause of the oil usage??quote:

Alright, I tried some, and it didn't seem to help. The instructions say to put it in and run the engine for 15 minutes, then change the oil. It also says it can take up to 1000 miles to stop the leak. How the heck can it still be working for the next 1000 miles if I drained it out??
Also - the thicker 10w40 doesn't seem to have helped either.
It's a Cherokee with the 4.0 inline 6, and the oil is leaking from the rear main seal. I didn't have too much hope that it would work either, but it was only 3 bucks. I'm just wondering how they can say it takes up to 1000 miles to work, when you drain it out before that 1000 miles?? As for the 15w-40, isn't that a little too thick for an engine that calls for 10w30?quote:

I don't know what the temperatures are like where you live, but I don't put much stock into the oil additives...much can be solved with a change to a different oil.
Have you considered one of the HDEO 15w-40's. I noticed the greatest reduction in oil consumption after I switched to Pennzoil Long-Life 15w-40, and this is even after running Rotella-T and Delo in the same engine.
Yeah, if it doesn't usually drop below 35, you should be absolutely fine with a 15w-40. Take a pick:quote:

It's got 99k on it, and the former owner really abused it. It's had 10w30 all it's life, and I just tried 10w40. Right now in the winter around here it's about 25-50 degrees...but usually no lower than 35.
Let me know what happens...quote:

I think every jeep 4.0 I have ever heard run had some sort of tap.quote:
