3.2-3.7...Depends how much drained, how much was remaining..Buy 4 quarts and you will be covered!

 

I drained it for a half an hour put new oil filter in and warmed it up to running temp. Then shut off and ran it for 30 sec. It shows full with 2.5 quarts

 

Did you change filter, and open the fill tube to let it vent? that seems low.

 

I wasn't able to get a full 3 quarts in either *shrug*

 

Yes , do you think some could be sitting in dry pump

 

Did you drain it with the machine at a angle?
