I'm not doing it, but knowing how long many cars run w/ sizable oil
consumption and comparing that w/ the one time mixture of say 32:1 of
2-cycle oil for 1 gal in 15 gal tank, I'll venture the chances are
pretty minimal in that type of volume to see discernable damage.
You have specific information to the contrary on actual volumes
That will not likely cause a problem.
Consider this. Most car manufacturers today believe that a quart of oil
every 1,000 miles is acceptable. (I don't, but that is another issue). In
any case they are talking about burning a quart of engine oil in 1,000 miles
That would be a quart of oil in maybe 40 gallons of gas. Mixing a gallon of
2 cycle mix with say 10 gallons of gas would give you far less oil per
gallon than the manufacturer says is safe, and it is oil designed to burn in
an engine unlike engine oil.
Damn, there is always someone who bring up an
Like you, I don't think 1 qt of oil per 1000 miles
is ok, but Ford does. Luckily, the oil level in
my truck stays pretty level, not down more than
1/2 qt maximum after 3000 hard miles. Otherwise,
it would go away real quick and become a Chevy or
I know for a fact that adding stale gasoline to the tank on a Farmall Cub
can run just fine and cause all the valves to stick when the engine cools
down. I do not know just how old the gas was or what the ratio of old to new
gas was but I do not put any more stale gas in my tanks after that
experience. Your experience may differ.
OK, I did this...
1 qt/1000 miles at 25 mpg --> 1 qt/40 gal --> 1/4 gal:40 gal --> 1:160.
My example of 1:32 in a 1:15 dilution tank is 1:15*32 --> 1:480
As you say, that's a factor of three dilution over what would be
considered by many as "normal". It's unlikely there are many vehicles
of significant mileage that don't use close to that per tankful
although, of course, not all of it is burned.
So, I'm still comfortable that such a dilution will not be the cause of
immediate failure of a catalytic converter. I would still try to use
any old 2-cycle prepared fuel by diluting it in a 2-cycle engine, but
think Red Cloud's concern is way overblown.
I don't think that is a good idea. Running out of gas (or having your
engine quit due to some problem in your car is one thing, generally is it
inconvenient. Having your engine quit in a boat boat is much more likely to
be life threatening.
I sure would not put anything into my boat tank that I would not put in
my car's tank.
