  Is it alright if I use T130W Sh*ll oil and add 1 oz zinc per quart? What weight should I use in the rear end and transmission?

  For the engine I would use a conventional high detergent motor oil like Pennzoil SAE 30 along with Red Line Engine Oil Break-In Additive which contains the proper amounts of zinc and phosphorus (ZDDP) to minimize valvetrain wear and promote long engine life.
If your engine has an oil filter, change the oil and filter every 2000 miles. If your engine does not have an oil filter, change the oil every 1000 miles.

For the transmission use NAPA SAE 90W API GL-1 Mineral Gear Oil. This is available in 1 gallon containers under P.N. 65-201.

For the rear axle use Pennzoil SAE 80W-90 GL-5 Gear Lubricant.
