Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few months. Anything over 6 months old use up in a 4 cycle engine. HTH Lou

The oil pump is a fairly simple unit, to access the drive gear and pump you first need to remove the clutch and sprocket ( the clutch is spun onto the crank with a l/h thread) check the condition of the drive gear pinion and the condition of the pump gear, with the pump removed you will find the pick up pipe from the oil tank, on the end is a filter, so make sure this is clean.
pull the chain clutch back towards the handle
it is not a chain lock but a clutch release that stops the chain from turning
pulling it back engages the clutch to drive it
I get asked this question a lot , im gonna have to make a video on this subject someday .
but here:
1st ck your oil viscosity/SAE it should be 30 and say bar/chain oil
next dump out entire oil tank and wash out with kerosene (you'd be surprised what I seen come out)
then remove bar and chain , locate oil outlet it's in body of saw near adjustment screw , use a small can of air to blow in this port softly , use a touch more of kero to clean this all out , refill tank with proper oil !!!! and run saw (no need to put bar/chain back on yet ) might take several minutes but oil should start to flow out hole !! stop saw and reinstall bar/chain then run again .. fixed !! if no oil comes out ever your oil pump is gonna need some fixing
for a low cost oil I use filtered used motor oil cut down with a dab of kerosene
all oil tanks on chain saws take Bar/chain oil this can be bought same place u buy 2 cycle engine oil most times , this bar chain oil most times is a 30W oil , if you change weights of oil then oil pump is not gonna add proper amount of oil to saw in use ,this will cause u problems !
Release the chain brake and remove the bar and chain. Clean the side of the engine where the bar fits to, then start the engine and see if oil oozes out of the side port on the engine. If it does, then clean the small oil passages in the drive end of the bar that run out from the large holes to the chain groove on each edge. If the oil does not ooze out of the port, then the oil pump, oil line, or oil filter in the tank may need service. Many oil pumps utilize a plastic gear that takes drive from the crankshaft behind the clutch and are prone to stripping the teeth of the gear. Hope some of this helps!

hello. the mix has not changed over the years. it is important however to use ryobi oil. go to any home depot and get the small bottle of ryobi oil that is enough for just one gallon of gas, use new gas fresh from the pump, and enjoy.
