The Lucas Oil I'm using is doing great for me, but I'll look into it.
What weight gear oil do you use?
I see some are 70w-90 and some are 90w-140
Gear oil is not my strong point. Lucas makes a dedicated oil for the differential & tranny.
I have heard good reviews on Mobil 1 & Valvoline full synthetic gear oil.
I also read the gear/tranny fluid is under low stress & can take 10,000 mile change intervals.
