Do some searching on here about Pennzoil Synchromesh, and AX-5's. Then ask yourself if you want to run anything else in it. I know I won't.

The spec for the ax5 is 75w-90 gear oil. Why is 10w30 motor oil being suggested?

Because the factory put out a dealer service bulletin in like 1992 that changed the spec. Also from experience, these trannys don't like anything over 30 weight, I know cuz I tried it. Because they are built to such close tolerances and heavier oil needs a place to squeeze out into. Also because they aren't as rigid as an iron case 4-speed. The heavier oil actually increases gear and bearing wear because the tooth load on individual gear teeth goes way up and things start to overheat with the wrong oil.

Actually, I haven't heard good things at all about Synchromesh. And given that the cheapest 10w30 provides absolutely perfect shifting from 80* down to -10*F in my transmission, I don't see why spending any extra money would be worth it.

Multiple people in that one thread report issues running it.

After pulling a valve cover off of a V8 that had been ran with Pennzoil all of it's life and finding, what could be best described as, a gelatin mold, I'll never run that crap in anything...to include my lawn mower.

Conventional 10w-30 is the new spec for the AX-15. I use the cheap stuff from Wal-Mart.

Here's why I use 10W-30 motor oil in my AX-15.

The Mopar gear oil part number used to be 4897622aa, but when you search that part number you'll see it has been superceded by part number 4761839AC which comes up as 10w-30 motor oil. Here's a link to search the Mopar part numbers.

Discount Mopar Parts Jeep Dodge Chrysler parts & accessories with great service

It's the "new factory spec" lubricant.

Based on that, I use 10w-30 motor oil. I buy the Wal-Mart "Super Tech" store brand oil because it's cheap, meets all the API (American Petroleum Institute) grade qualifications and I change mine often, at least every 6 to 12 months.

Here's a link to the Jeep Engineers Q&A thread here on JF where I questioned the Jeep factory engineers on this very thing.

Here's my question post....
