Ive got an ordinary 5 litre petrol can full with unleded petrol how much two stroke oil do i have to mix in?
Answers:
1 litre = 5000cc
5000cc divided by 25 = 200cc
200cc per 5000cc (or 1 litre) = 25-1
If your sure the mix ratio is 25 to 1 then you need 5 divided by 25 or .2 liters of oil for each 5 liters of fuel. Make sure the mix ratio is correct. Some outboard motor engines use mixes as rich as 10 to 1. Make sure you mix thoroughly.
Got a manual? They should tell you what proprtion it is normally mixed to. Word to the wise.--- This is a good move, I have seen many engines burned up because the oil doesn't get mixed int to the gas for some reason (bad oil pump is a good one!) There have also been a number of cars with 2 cycle engines that have been ruined because the "automatic" mixing of fuel didn't occour!
Calll Dealer and ask what mix should be, - if you don;t have other scources available! You can get the measure in conversion tables (from sae -to - metric) on internet also! (find out how many ounces of gas is 1 litre, - or how many ccs of oil is 1 litre).
From there you can then get right mix by using the approprioate conversion (to make two of the same) standard measurenment!
Before assuming its the oil pump, Have a look in the 2stroke tank to make sure the outlet isnt blocked.
Those tanks have a funnel shaped sump which is the perfect size for the paper disc that seals the lids of 2stroke oil bottles,
The ratio should be on the oil bottle. The ratio will vary from brand to brand.
25:1 is a little on the rich side. You need to ask your local bike shop I would suggest for a 125 around 32:1 is a better ratio else you will clog up your plug all the time.
Should be a 50 to 1 mix, so 100 ml oil per litre of gas.
