What kind of oil does a homelite chain saw use?

Any 2 cycle oil can be used. Most of the older models (pre 1995 use a 32:1 ratio), newer 2 cycle engines use a 40:1 or 50:1 ratio. It will not hurt the engine to use a lower ratio, but it will hurt to use a higher ratio. Even in a brand new 2 cycle engine that calls for a 50:1 ratio I use a 40:1 ratio which is better for the engine by helping it run cooler and last much longer. This is true for all 2 cycle engines no matter what it's in, a chain saw, leaf blower or trimmer, however its more important with a chain saw which is under more load than a trimmer which is under more load than a leaf blower.

Of course you can always call HOMELITE at (800) 242-4672 and find out the correct ratio for your model.

P.S. YES parts are still available for 25 year old HOMELITE saws. If HOMELITE does not stock the part you need they can give you the phone number for an obsolete parts dealer. I just last week got a guide bar adjustment kit, guide bar bolt and pull start pulley( which has teeth that ingage the fingers on the fly wheel. They even have pistons, rods, crankshafts and engine block for my model so dont give up hope. parts are still out there!
