Homelite CSP 3314 Chainsaw

the ratio should be 25 to 1 so 250 mls of oil for 1 litre of petrol

Generally small tool 2 stroke engines run on a ratio of 50:1
That's 100ml of oil in 5L of petrol

Generally 2 stroke engines work on a ratio of 50:1
100ml of 2 stroke oil in 5L of petrol.
Use good quality 2 stroke engine oil for the mixture, Stihl and Husqvarna both have high quality engine oils, designed for more efficient lubrication and emissions quality.

If it is 2 stroke, take petrol /fuel and mix it with preferably synthetic2 stroke oil.

Ratio is usually 10L petrol mixed with 200 ml or 2 stroke oil, that is the best result, used it on my chainsaw, strimmer, moped, working for years without a glitch.

Hi, basically you fill it up every time you fill up with two stroke fuel as it uses about 3/4 of a tank of bar oil to a tank of fuel. Regards Phil.

that Poulan saw is 2-stroke and needs a fuel oil mix ( 2-stroke oil ) at a ratio of 40:1.

You need to mix 3.2 oz of 2 cycle oil to 1 gallon of gas. Some may disagree but a 40:1 ratio is better than a 50:1 mix. It gives more oil in the mix to keep the cylinder/piston lubricated. Any less and you will burn up the engine. With this new mixture you may need to get a professional to readjust the carburetor to this new mix.

Generally you're looking at a 50:1 ratio on most chainsaws and I wouldn't see any reason the homelite should be any different. Usually it's one 2.5oz container of the oil mixture to one gallon of gasoline but check the label to be sure.

16:1 ratio for most 2-stroke oil brands. A service manual recommends tro check the ratio marked on the bottle if using Homelite brand 2-stroke oil. For other oils, 16 parts of gas to 1 part of oil.

For 1 gal of fuel, that is 270cc of oil required to meet the 16:1 ratio.

Most McCulloch saws use a 40:1 oil ratio if using McCulloch branded 2-stroke oil. They state 20:1 for other oils, but this is probably overkill as most name branded 2-stroke oils these days are pretty good. I would probably go for a 30:1 or 35:1 mix to err on the side of caution. This will not affect performance, it may just mean you need to change spark plugs a little earlier than usual, but the cylinders will at least be well lubricated.
