Poulan Woodshark 1800 bar oil too heavy

tylerswire · Jun 13, 2021

Took my saw apart to clean it up and blew it out with air compressor. Thinking there might have been a seal where the blue arrow is pointing to, because now it's using way too much oil. I've tried using the diagrams on the different parts sites, but can't seem to find anything. Does anyone happen to know if there is a seal or something that should go in there?

That’s the one way check valve for the oil tank vent. As the oil level goes down, the air goes in through the valve. If you blew in that valve with the air compressor, you might have lodged the check valve in the open position. Thus causing more oil to be freely pumped or it’s leaking out the check valve and going into the chain and you won’t notice it leaking, but just as high oil consumption.

Nope, and those micro series don’t even use a bar plate...only the tubing end is stubbed out there in your pic.

Pressurized oiler systems like you’ve got will over oil when it’s used in hot weather.

Try searching the forum for an old post that had a class paper written by a Texas A&M engineering student titled “COMPARING THE PROPERTIES OF COMMON BAR OILS IN CHAINSAWS FOR USE IN A COST BENEFIT ANALYSIS”. I can’t find the old link, as the AS search is messed up.

It listed the Tractor Supply Bar-n-Chain brand as being the thickest/highest viscosity chainsaw bar oils. Only Poulan or straight 30 weight oil is listed in the owners manual, but it’s too thin in hot weather.

Your right. I should’ve looked closer at the pic.

After all this reading on bar oils, thinking I should have titled this post something more like "Poulan Woodshark 1800 bar oiler gushing oil!"

I didn't find anything in the AS forums, but Google turned up something from back in 2012... appears to be the feller who was working on the doc.

I've used this saw many times, even in the summer and never had the issue until I cleaned it out with the air compressor. It really goes to spraying oil now. I'm going to give the TS oil a run to see if it slows things down any.

Thanks ya'll.

Had a quart of Echo brand sitting that came with a chainsaw sometime back and tried it. Thickening up the bar oil seems to have done the trick. I think I'll try the Tractor Supply brand next time I buy. Thanks again for the info fellas.
