Just use a non-sythetic 80-90W & posi additive if needed, on the break-in, i just ran mine for 50-60 miles & let it rip lol, if the rear is set-up right, i feel theres no need for a long break-in period, just like all my engines i've drag raced, a good 20 miles on her & off too the track for some shakedown runs, never ever had an issue, so run her around for a bit & have fun, just change the gear oil after 4-500 miles

I would not "rip" it for at least 300 miles. The heat cycles will temper the gears.

No posi additive is needed for the Truetrac. Bob
