I wanted to ask what the recommended fluids are for the drive line. I believe the engine is a 235,tried to run the numbers but no luck, it doesn't have an oil filter, the transmission is a three speed, the rest is supposed to be stock for a 53.
What oils should I use for the engine,transmission and rear end ?

Use 80-90 gear lube in the gear boxes. GL-5 must be used in the rear end & can be used in the trans.

All they carry now (at our store) is Rotella CJ-4, which is the "new" formulation. It actually has less ZDDP in it than the Castrol GTX 20-50w I've been using. According to the research I've done, you'll need to find the "old" CI-4 formulation to get more zinc than the Castrol GTX 20-50w. | | | | | Joined: Jul 2007 Posts: 66 'Bolter | | 'Bolter Joined: Jul 2007 Posts: 66 | Okay thanks everyone.
I know that the Rotella T15-40 is a Shell product but, who makes the GL-5 for the rearend and transmission ? | | |
