Just restored a a 1960's lawnboy mower with a D-400 motor on it. My question is: what is a good gas/oil ratio for this old gal? I have been told everything from 16:1 to 50:1.
Also, can I use a synthetic? I use a synthetic marketed by Honda in my little Honda scooters and it works real well.
One gentleman on the web mentioned an oil called Opti-2 and swore up and down he mixes it at a 70:1 ratio and uses it in his commercial lawn equipment.
So confused as to what I should put in the old gal.
