2 Stroke Fuel

[Ed in Tampa]

At one time I used the old Arco Graphite some. Never had a problem with it but it just went off of the market.
I used to use it to make my own chainsaw bar oil mix. One quart of Arco Graphite oil, two quarts of the cheapest oil off of the shelf and one can of STP. It worked absolutely great... I was cutting "a lot" of firewood both for myself and to sell. It did make the chains a little messier to remove and grind and was hard to wash the black out of your hands.

ARCO graphite that was the one. Great stuff. I switched to it right before it went off the market.
Another additive I used was Molybdenum Disulfide. I would add it to the oil at each oil change. This was long before ARCO graphite. I never had an engine failure I could contribute to lube.

In the two strokes there was this oil Blenzoil I think that came in a gold and black can in the 70's. I think it was made from castor beans. In any case I loved the smell of it. In races I would love to get behind a guy (one I was lapping )burning the stuff. Kind of like bananas, or something. I can remember that smell. Now castrol never had the smell and I think it too is from castor beans.

That's how they make ricin nerve gas!

Perhaps that explains why I was crazy enough to race the thing to start with.

Oh do my bone, joints and other body parts regret all the fun my body had in my younger days.

That brings back memories. My first RD-400 had a crank go bad. I couldn't afford to get it rebuilt. (Those things were pressed together, and with a 2 cylinder engine, that's a LOT of aligning.) I was able to find an RD-350 motor, for about 1/4 what a rebuild would cost. Put the crank, pistons and cylinders on the 400 engine. Crank was about 1/2 inch shorter stroke, which means the 4 flywheels were 1/2 inch smaller, too. That left a fair amount of extra room in the crankcase. Running normally, no problem, just lower power, as to be expected from the lower displacement.

BUT, since the RD series had oil injection, and the crankcase had extra room, some of that oil would build up in the crankcase. Some guy in a car would tick me off, I'd pass him up, downshift a couple times, and hit full throttle.

That would clean out all that collected oil. Wonder where it went?:D

But, that was a long time ago, in my youth!

Where I live, it's damn near impossible to get gas without excessive amounts of both.

I use non-oxygentated fuel in the snowblower, lawn mower, chain saw and emergency generator. Yea it's hard to find but we have a group called Minnesota Street Rod Association, who like to run it in their cars and put a list, on their website, of all the gas stations in the state who carry it or racing fuel.

You might see if there is a similar organiztion in your area. Just a thought.

What is non-oxygenatated fuel? I don't think I ever heard of it.

My understanding, and I'm no chemist, is that Oxygenated fuel is an ethenol blend non-oxygenated is pure gasoline no ethenol or alcohol. In our area it's 91 octane.

Probably thought up by whomever came up with non-oxygenated nitrogen for yer tires!:D

So spending time in a bar is getting oneself oxygenated?:rolleyes:
