40:1 instead of 50:1? - The Forestry Forum
WEBSep 30, 2024 — Me: "What fuel to oil mix ratio to you recommend for the longest engine life of a Husqvarna 385xp used for chainsaw milling?" Husq: "Thank you for contacting Husqvarna. The best fuel/oil mix will be the 50:1 ratio using quality 2 cycle oil that is designed for chainsaws, and use fresh fuel, 89-93 octane for best performance."
40:1 or 50:1 mix on 372XP - Arborist, Chainsaw & Tree Work Forum
WEBOct 13, 2005 — There was an enormous difference in heat when the saw was running with 50:1 vs 40:1 or 35:1 When plugging hard, way too much heat - to the point where I wasn't comfortable to continue using the saw Completely resolved by raising the mix I've encountered the same thing with a 2-stroke trials bike, which I now run much richer
40:1, 50:1 does it matter? - Arborist, Chainsaw & Tree Work Forum
WEBJan 11, 2008 — There has to be a reason that Stihl would say use 50:1. The other is think...what 40:1 and 50: 1 is. 40:1 - 40 parts gas to 1 part oil 50:1 - 50 parts gas to 1 part oil 50:1 is gonna run hotter and faster. The 200T, has been designed to run at 50:1, and that is what we should run at.
Oil Fuel ratio - Arborist, Chainsaw & Tree Work Forum
WEBSep 21, 2018 — Just browsing on Huztl's website and noticed the assembled MS660 and 372 clones (G660 and G372) both indicate a fuel-oil ratio of 25:1. Leads me to wonder why the big difference between Stihl & Husqvarna calling for 50:1 and Huztl using AM parts calling for 25:1. The Huztl saws are assembled...
Oil/Fuel Mix in Older Chain Saws - Arborist, Chainsaw & Tree Work …
WEBNov 25, 2006 — I'm looking in a manual for an older Husqvarna saw I acquired, and the recommendations for the oil/fuel mix varies from 1:20 ('oil'), 1:25 ('pre-mixed oil'), to 1:50 ('Husqvarna Twostroke oil'). I use a good quality 2-cycle chainsaw oil, so I am not concerned about using the 1:50 ratio, but it makes me …
50 to 1 for old equipment???? - Arborist, Chainsaw & Tree Work …
WEBMay 15, 2005 — The 50 to 1 had lost something like 30% of its original horsepower at the end of the test. For kicks or whatever the test group put the 15 to 1 mix in the engine that lost power on 50 to 1 and checked horsepower again and it came back up very significantly. That is why I choose the richer oil mixtures most of the time. Primarily I use 25 to 1.

40-1 vs. 50-1 - Arborist, Chainsaw & Tree Work Forum
WEBMay 27, 2011 — Supposedly ported saws run cooler, and since they move a greater volume of fuel mix through the cylinder, with a lesser proportion of it burned, why would they need more oil? Just curious. More generally, the difference between 40:1 and 50:1 is much smaller than the difference between a saw that is properly tuned and one that is a …
16:1 32:1 40:1 50:1 fuel mix - Arborist, Chainsaw & Tree Work Forum
WEBAug 17, 2011 — I have a pile of saws, mower, hedge trimmer, weed wacker that are all 2 cycle engines. I use the same can of gas for the whole mess, 32:1. There is a Husqvarna 50 in the family that was purchased in 87, cut many cords of wood, still running today on the same piston, tuned at 32:1. I don't like the ethanol in fuel due to the effects on the fuel ...
Which Pre-Mix Gas Do You Use? Are They All The Same?
WEBAug 11, 2019 — Since getting my first chainsaw, I have been only using pre-mixed fuel. Usually 40:1 but sometimes 50:1 if they are out of the 40. When I got my first Husky saw, I used Husky fuel, and when I got my first Stihl saw, I used Stihl fuel. Since then, I have basically just been using whatever is on sale.
