I am planning to change out the gear lube in my front and rear diffs and transfer case. I prefer Mobil 1 but am not married to it. I am hoping to avoid having to pump from multiple quart bottles and would like to purchase the gear lube in a gallon jug. Does anyone know where Mobil 1 can be purchased in the gallon jug rather than only in quart containers? Any recommendations for gear lube other than Mobil 1. Thanks in advance. Phil

 

I have just purchased 6qt of M 1 75-90 at advance using the buy 25 get $10 off. So far $66 of gear oil for $46. Going to pick up 2qt More and a filter and save a other 10. Look for the coupon online.

Also - their gallon jug of rotella is onsale for $10.99, but you can't use the coupon.

Edit: To answer you question, I have no idea on where you can get any gallon jugs, or what other type of lube to suggest. Just merely telling you about the coupon deal and the low priced oil

 

I just bought 4 qts of Wally World brand semi syn 85w-140.
I will be doing both diffs tomorrow after work.

 

Buy redline gear oil. It comes in gallon jugs and is pretty much the best there is. Though M1 gear oil is good stuff too.

 

I was looking for gear oil in gallon jugs as well hoping to save some money. The only thing I could find in other than a quart size was at a Farm Supply Store. They had a two gallon jug of some off brand for about 25 bucks.

I waited and bought quarts of the 75-140 for the transfer case. I had already done both diffs with Mobil I in the quart size.
