What engine oil and gear oil?
I recently got a '69 C10 from my grandfather. It's got a '71 307 and a TH-400. The rear axle is a '70 12 bolt. It appears to have a posi and about a 3.24 gear.
The truck runs pretty good. I want to go over everything before I run it much. What engine oil does this engine need? I'm guessing 10w-30 but I'm not sure. Also, what gear lube for the rear axle? Do I need some kind of additive for the posi? I'm pretty sure the trans just needs good old Dexron III.
