oil mixture question gang.

[kenvb]

i found my wifes first sled.79 ET 250 . dont trust the oil injection on it anymore.so whats a good mixture. 20-1 40-1 ? forget. quart of oil to 5 gal gas is 20 to 1? half quart to 5 gall is 40 -1 right ? and Premium gas right? she was pissed at me for selling it in 1990 when we moved to Barrhead. last month i found it in Edson. ad said. looks like crap. but starts in 2 pulls cold. 1 after that. so she sewed a seat cover for it. i put on new windshield. all new controls. except kill switch and its ready to go.

On my race sleds i ran 32-1 or 40-1 were the two mixtures i always ran, go to canadian tire and buy the little clear jug tells u how mich oil for how many litres of fuel and has all the common mix ratios on it its like 7 bucks but pretty handy and
no more guess work

It depends on the oil you plan on running. Some oils 32:1 some 100:1 others are in between. I always went around 40:1. But it’s been years sense I mixed gas.

I think 40:1 would be more than sufficient. With a quality 2 stroke oil you could run 50:1 safely. Years ago I ran 50:1 mixture in an old 72 T'NT 440 with no problem and the recommended was 20:1 in the original owners manual. LOL, carried a box of spare plugs all the time the first year when I was running 20:1.
5 gallons imp to 1/2 qt is 40:1. Instead of using imperial though just use metric. 20 L to 500 ml.

Oils cheaper than motor parts. Don’t think there is a down side to over oiling except pipe spooge or fouled plugs.

40:1 would be fine Im sure

 

[Couch]

50:1 if i recall. Oil injection on the 250s didn't seem to have issues. On the 300s they had a plastic shaft that would break. The 250s are bullet proof - still loads of 250s and bravos around.
If you're not sure / dont want to trust it fill oil tank to the brim and mix fuel tank 50:1 and then check the oil tank after the first 1/4 or 1/2 of fuel is used ....

we mixed 50 to 1 for years and numerous makes and models of sleds, oil from canadian tire

I still run my vintage sleds on 50:1 if you have a 25 liter gas can you put 500ml oil in er, easy peasy

I used to run 500ml to 20L jerry can on my old 83 enticer 340.
