What octane gas should I use in 1960 gale 35hp/omc?

[ronboonville]

Title says it all, have been using cheap gas in almost everything I own. I noticed on my johnson gas tank it says use regular gas or white gas. also it says avoid third grade low priced oil, use marine oil. I have been running 20:1 mix with seafoam added about three gallons through it, but most of that was when in only ran in barrel on one cylinder, now I think I'm already to get out on the water. please advise as to octane and what two-cycle oil to use, I usually use what ever they sell at walmart, maybe super tech. I use the same oil in my nissan 90hp and have had no problems, thanks, ron

I really don't think they sell cheap gas!

nothing wrong with regular gas in that motor.though im not 100 percent positive, i believe the mix is 24:1.

Yep, 24:1 mix, using TCW3 rated outboard oil, with 87 octane gas.

that's correct, I always have to do the math. 1 quart to 6 gallon tank. keep thinking I wrote this on my poly tank, but just checked, and I didn't. well maybe tomarrow. thanks 82rude and Chinewalker.
