Is this gas/oil mixture for the snowblower OK to put right in the car's gas tank?
I sure as hell wouldn't do it. It may or may not do damage, but why risk it?
I've used gas/oil mixtures in my line trimmer and pole saw even after the fuel sat for 8 to 9 months. No problem at all. Just keep the container sealed.
That's what I say - why risk it.
Oh ok, may be we'll just seal it up then. -- "When you get lost in your imaginatory vagueness, your foresight becomes a nimble vagrant."
