This is probably a dumb question, but I'm gonna ask it anyway. Will the
oil in old 2-cycle engine fuel hurt the oxygen sensor or catalytic
converter in my truck if I pour a gallon or two in with a full tank of
gas? (That's how I got rid of it when I had an old truck w/ a
carburetor and no converter.)

I assume the dilution is great enough that it won't be a problem.

BTW, don't try this with dirty paint thinner.

It has never hurt my '93 fuel-injected Dodge V8. As you say, the
quantity is very small assuming that the vehicle's tank is large and
close to full. If that bit of oil is going to seriously hurt anything,
what about an engine that is burning a quart of its own oil every couple
of thousand miles which wouldn't be at all unusual?

I do it with a 1991 Mercuy Tracer, 4 cyl, FI.

I put in a half gallon of 2 cycle mix from the hedge trimmer with a full
tank (12 gals.)
in the car. Do that in the fall, about 2 weeks before my annual change
of the fuel filter in the
Mercury.

I also put left over chain saw gas ( oil mix at a 42:1 gas to oil ratio)
in the car, if I have
any. I cut so much wood, though, for the wood stove, that I seldom have
stale, left
over chain saw fuel. Do the same with the left over gas from the mower,
but thats 4 cycle engine and no oil, just Stabil.

So far, (knock wood), so good.

YMMV.

Literally.

But that's it's own oil. Of course it doesnt' hurt it. It's like
eating food you've sneezed on or spit on. It's your sneeze and spit,
so it won't hurt you.


OK, i'm kidding.

Hi,
Good 2 cycle oil is very clean burning any way.
I don't think it'll do any harm to your O2 sensor.
