I run the cheap because it's "better" and it's in huge supply at the farm store. In the south, I don't guess cold ever gets cold enough to slow down the oil. @Rifleman97 Project Farm video convinced me last year.I run the cheap bar oil, because it’s cheap. Engine oil in a pinch but it doesn’t work as well, slinging off too much.
When it’s pretty cold I will cut the bar oil with diesel for better flow.
Don't tell me we're about to take AH down the oil rabbit hole. I've been down it several times, especially on motorcycle forums. Rotella 15-40 is about the best oil you can put in anything that's not still under warranty. I've got a box full of oil filters (30 I think) that I cut open to decide what's good and what's not (was a fun project the moto world got a lot of kicks from).The cost of Stihl or Echo bar oil at my farm store is about 22 to 26 dollars, the harvest king is 7.99. A chain for my saw cost $25 and a bar is $60.
With the $14 savings on bar oil I can purchase a brand new chain every two gallons of oil I use or a bar every 4 gallons.
I can’t see the name brand oil making bars and chains last enough longer over the harvest king to ever pay me back on the high cost of the oil.
Shoot, the Shell rotella 15w40 I dump in my pickup and tractors only cost $16 per gallon, and it has a lot tougher job than bar oil does.
The only thing name brand bar oil is, expensive.
All my saws are early 1990's. I run Husky 2-stroke oil because it has the fuel additive/preservative built in - 40:1 with non-ethanol gas. I run cheap, low-vis bar oil; I want the bar to stay wet and loose to keep it cool and keep chips and dust away from the oiler hole. (Things that make you go "Hmmm"... they guy who sells expensive, sticky bar oil also sells chains and bars...?). Not too worried about the little saw with the 16-inch because the oiler is running all the time; it stays wet. The 20-inch bar is an original and I make sure to have a new oiler on that saw that floods the bar. 32-inch Husky and Tsumara light bars cost 160-200 dollars each and they need a lot of oil to keep cutting big hardwood. I nearly burned up my Tsumara 24-inch light bar on pine stumps because Husky oil wasn't flowing like I wanted.
Our 280k '03 4Runner has a spin on filter... I run Mobil1 filter and 5-30 Mobil1 High Mileage. The 100k '22 Lexus GX460 has a filter housing; I run factory filters and Mobil1 Extended Performance 0-20. Both get changed every 5k miles. The internet gurus want you to switch to heavier oil, but I believe in sticking to factory weight and changing at HALF the interval they are forced to recommend these days. I'm having no problems and sleeping well at night.
I couldn't either. That 880 & Husky's 3120 I believe are used a lot for milling, or crews last resort for certain applications. Double the weight & sheer size .. 404 chain is indestructible.
