Fuel mixture 20:1

[eddie1]

ok manual says run 20:1 and mix 250ml into 5 gallions to run at 20:1

online calulators say to use 920ml(+/-).


sad thing is i just fallowed the manual and mixed 250ml with 93 octane gas. Did I just ruen a brand new motor?

or is my manual right?

What bike do you have?

If you have 250 ml of oil and you want to run it at 20:1, you will want to put the oil into 5 liters of fuel, not 5 gallons.

Looks like you were running about 77:1 or so.

If you did not push it hard and only rode a short time and you used a good quality oil, you might be OK.

Mostl likely you will be fine.

FWIW, on a long trail ride with my KDX200, my buddy and I got lost. We were a long way from our camp and found a camper way out in the middle of nowhere. We each got straight gas from him for our two strokes (no other options available). I figure we were running about 100:1 for maybe 20 miles. We were careful not to use any more throttle or fuel than necessary. The bikes showed no ill effects.

FWIW - It probably took some hours off the life of the top end, BUT many 2-Stroke aircraft engines are commonly mixed at ratios as thin as 100:1.
