Anyone know how much oil one holds and what type? Planning on either synthetic 80w-90 or synthetic 75w-90. Thanks for any advice.

I'm pretty sure it is right around 4 quarts. Maybe 4.2 to be exact, if memory serves me correctly.

I just did mine a few weeks ago. 1 gallon will fill it to within 1/8" of the hole.
They need GL-4 type, and it's getting hard to find. I bought Sta-Lube from Amazon, after not finding it local.

I am not familiar with GL-4 ? I assume a gear lube ? What viscosity ? Mine is stiff when cold particularly in the winter.
