Reply To: Advice about oil/fuel mixture in old outboards

[Bob Wight]

Oiling ratio is a real Pandora’s box.    If your recommended ratio is 8 ounces per gallon (16:1) you might go 20:1 with modern day 2-cycle oil.   But I’m with David on this one – whatever the manufacturer originally specified, I stick with that ratio.   I figure oil is a lot cheaper than trying to find parts for an old motor if you have one seize up due to lack of oil.
