Re: 1961 Johnson 18 HP oil mix Question
Well boys and girls, I remember when OB oil was a can of Gulf Oil's 30 wt automotive engine lube at the ratio of a quart to 6 gallons of gas........geez what a quagmire. Even remember the red cans of Amalie "Better than it has to be" outboard oil in the early days. Talk about smoke and fouled plugs, and carbon...yucko!!!
Then in the '60's ScottAtwater (McCullough) comes out with two oil mixes, one is 50:1 in a 16 oz. yellow can as I recall, which is about when the industry developed that mix, and then they had a red can that was 100:1. By the numbers it had to be 8 oz to equate to the numbers but I'd swear that it was the same size as the Winn's Friction Proofing available in the day which was 4 oz; little bitty sucker.
Anyway, I had a '59 18 hp Rude that I bought new for $400. I was living at home and built a stand for it and kept it in my room (where I slept) so that nothing would happen to it.....my mother was an extremely tolerant person....obviously the fuel tank remained out of doors.
I went into the USAF and was stationed "afar" and on one weekend when I came home to be with my honey....which is why I joined the service in the first place, I had no money and no professional education.
So I took my prized possession, that I kept in my room, polished, had maybe 10 hours on it and hocked it for 40 measley $$ so that I could get back to base. The babe, has been my bride for over 48 years now and even though it was tough at the time, joining the service was the second best thing I ever did....you obviously know what the 1st thing is.
Today BIA has certified oils and it seems that current TCW-3 oils will run anything at a mix ratio of 50:1. How does it compare to the old stuff?????? Apples and oranges. Would I do that? In a heartbeat.
