what happens when you run a four stroke, on 2 stroke fuel?

will it produce less power? will it b**g*r it up?

If your talking straight fuel (petrol) nothing..

back in the old days ... 2 strokes ran on 2 star.. if it wasnt available then 3 star... then 2 & 3 star were phased out... leaving 4 star...

so you had no option but to run a two stroke on 4 star :)http://hovercraft.org.uk/images/icons/smiley_icons/icon_smile.gif

then along came unleaded et al...

now i gues your meaning... what happens if i put premixed fuel (fuel oil) for a two stroke, in an engine that has a seperate non oil burning lubrication system...

smoke:)http://hovercraft.org.uk/images/icons/smiley_icons/icon_smile.gif lots of blue smoke, as the oil gets burnt in the combustion cycle... it will be like running a car with knacked rings.. but you wont have loss of compression http://hovercraft.org.uk/images/icons/smiley_icons/icon_smile.gif

your plugs will suffer, as they will be subjected to excess oil, so they will eventually foul (carbon build up)

depending on how much youve run, a good healthy dose of redex will help also

Nah, don't worry about it! I've stuck 2 stroke in my cars for years and never had a problem! Obviously its not something to do on a regular basis or if you have a super tuned up engine. Putting some in a half full fuel tank will dilute the mixture even more.

These days two stroke oil probably doesn't do your catalyst any good, - if you’ve got one.
