Greetings All,
I just bought a used 2016 Jeep Wrangler (Dana 44 Rear Diff with Trac-Lok) with 42K Miles on it.
Since I am not certain of the maintenance history I have decided to change some of the fluids. For the differentials the owner's manual specs Mopar Gear & Axle 80w-90 GL-5 (I will not be towing). However, the Mopar fluids are very expensive here and the parts guy at the dealer actually told me to go to a local parts store to purchase fluids as the dealer prices are outrageous (honest guy). At this point I already have the Mopar LS additive and I am only looking for Diff oil.
A wide selection of Ravenol oils are available to me from a local parts store, so I used Ravenol's "oil finder" to see what product the company would recommended for the Jeep. To my surprise the top recommendation in their listing is a semi-synthetic TGO 75w-90, and number two in the list is a synthetic VSG 75w-90 that appears (to me at least) to have better specs than their top recommendation.
Am I missing something here? Is there a reason why I should use the semi-synthetic TGO over the fully synthetic VSG?
Oil specs linked below:
Ravenol TGO Semi-Synthetic 75w-90
Ravenol VSG Fully Synthetic 75w-90
