Small Engines (Lawn Mowers, etc.)/Chainsaw question...


Mr. Jones,
I have a rather "general" question about chainsaws, and I hope that's not outside your specialty.
I have Stihl "Farm Boss" that's an excellent chainsaw, and I use it a good bit.  If I run low on chain oil, can I use motor oil as an temporary substitute?

Yes, you can use motor oil if you have to but...motor oil is a thinner viscosity and had different additives in it.

Motor oil will not lube the chain and bar as well as bar and chain oil.  If you use motor oil frequently you can cause premature wear to your bar, chain and clutch.  Considering it costs over $100 to replace the bar, chain and clutch, the bar and chain oil is a wise investment to ensure you get proper lube to get the maximum use from your bar, chain and clutch.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
