Re: 12 bolt gear oil
Best gear oil to use is Red Line Lightweight ShockProof. It has gl6 where as most others only have gl5. The gears never really touch each other, the oil is a cushion.

Second vote for Red Line Lightweight ShockProof, 1 qt. Plus they support sportsman racing and are one of our sponsors.

Re: 12 bolt gear oil
If the cover retains the OE design, a quart of gear oil will be out in the axle tubes before you pass the 330' clocks. Think about that.

Re: 12 bolt gear oil
I wonder if anybody has ever tested oil level in a 12 bolt. I think that your better to have a slight over fill then an underfill condition. If there is not enough oil then the gear runs dry and you create friction. I can't imagine there is much ET between running 1 and 2 qts. That's just me

Re: 12 bolt gear oil
The gears will not run dry with 1 qt. My only concern would be the axle bearings. Sounds like 1 qt is what many use.

I've run 1 qt. 85-90 synthetic, quite a bit ,and never hurt anything. The cover design on a 12 bolt, directs oil right to the side bearings anyway. That being said, it's been determined by several racers, that a lot of the oil goes up into the axle tubes anyway, and that 2 qts. won't hurt you much. A personal observation: If you are going to try some kind of super light concoction for a record run or something, make sure the gears are well broken in with the regular stuff first. :-(
