20 oz. is probably most typical, but not in every case.
They've been making these things for 60+ years.

Robar: Use the old tried and proven method . Utilize your Engine Oil Dip Stick . As Bill has advised 20 oz. is normal but once your crankcase has been drained add 10 oz and check level with dip stick and only fill to just under full . Better a little low than over filled which will be deposited within you air filter and cause carbon deposits and worse .

My Lawn Boy 4 cycle with 6.5 hp has a dipstick, but for what ever reason, the oil level is just barely touching the bottom of the dipstick.....even after I added a good amount. I'll probably just drain it and refill to be safe.
