What is the oil capacity for a 36 pd? The engine owners manual says something like 70-84 ounces, but doesn't specify what model requires how much. I know the pd maintenance thread says 2 qts, but that's less than what the manual says.

Also I'm thinking sae 30 for the hot summer, and 10w-30 for the winter once it cools off.

You will never get all the oil out of the motor. I usually drain it, fill it with about 1 3/4 qts, check the dipstick, then run it for a few minutes, and check again.

I keep mine just above the add line. You do not want to overfill it!

If i drain mine and put 2 quarts in, it's right on the add mark after running for a minute. 5w 30 in mine...
