With a 40:1 mix you mix 3.5 ounces of oil to one gallon of gas, where with 50:1 you mix 2.5 ounces of oil to one gallon of gas. That said, I run 40:1 in everything and have not problems, but 50:1 in a 40:1 motor might be running a little light on oil and cause the motor to burn up sooner. If you run 40:1 in a 50:1 motor, you’ll get a little more smoke and probably foul the plug sooner, but that’s nothing a little sand paper can’t fix.
I have a Stihl chainsaw, Echo chainsaw, Echo blower, Husqvarna weed eater, Shindawa weed eater and use the same mix in them all. I mix about 2.5 gallons each time unless I know I can’t use it up in several months time. I usually use Echo or Stihl mix and have been told to stay away from the 100 to 1 synthetic mixes.
I have 2-stroke powered equipment that asks for fuel/oil ratios ranging from 25:1 to 50:1.The tools that ask for 25:1 are old ones and they weren’t happy with actual 25:1 ratio fuel while using nowadays 2-stroke oils – they were smoking heavily , spitting excess oil out of the muffler and getting oily spark plugs. I got fed up with all the different ratios and switched to 40:1 on all my 2-stroke equipment!
is weed eater and chainsaw gas the same Related Question:
Can you use weed eater gas in a chainsaw?
I use the same for both of mine with no problem. I do the same, weedeater is 40/1 chain saw is 50/1, I run 50/1 in both. The weedeater smokes a very little bit but it runs just fine.
What kind of gas does a weed eater use?

Can I use premium gas in Weed Eater?
As a result, while you can use an ethanol-fuel mix up to 10 percent ethanol, more than that not only can damage your weed eater, but it’s actually illegal. Always go with premium gasoline, preferably between 90 and 93 octane rating. Lower octane contains too much ethanol, and higher burns too hot for a smaller engine.
Is Weed Eater and lawn mower gas the same?

Do all chainsaws use mixed gas?
The fact is, most chainsaws are built with 2-cycle (or 2-stroke) engines which require a mixture of fuel and oil to run. Oil is mixed with gasoline (i.e. petrol) so that it can lubricate the internal parts of the engine while it operates.
What is the best fuel for a chainsaw?
Use a minimum of 89 octane gasoline and always use fresh fuel. Only buy enough gasoline that you can easily use up within a two- month period. For air-cooled, two-cycle engines, use a quality mix oil that meets the engine manufacturer’s recommendations.

What happens if you run straight gas in a 2 stroke?
Without lubrication, it’ll cause high friction, causing heat and causing metal filings from the piston rings knocking around, and losing a seal. In a way, oil counteracts all of these. If it’ll still turn over, flush the fuel, and put in the correct mixture of petrol and oil.
