What is the best oil/gas mix for a Husqvarna rancher chainsaw?

Fuel oil ratio should be 50.1 preferably with Husqvarna two stroke oil.

Unleaded fuel with Husqvarna two stoke oil mixed at 50-1, for the chain you need a non fling chain oil, both should be available from your local Husqvarna dealer.

50:1 ratio 2.6 fl oz of 2 stroke oil to 1 gal of fuel

50:1

What we always say is if you are useing Husqvarna two stoke oil it is mixed at 50-1 if you are useing anybody elses oil it should be mixed at 25-1 as we do not know the quaility of other peoples oil, avoid oils from super markets and mass traders, always try to use Husqvarna two stroke if possible, its not the cheapest oil out there but remember this a new cylinder and piston for this saw retails for £217 + tax, so cheap oil can work out very expensive

Clean or replace the fuel filter. Check the fuel lines for decay or other damage. Check the muffler for plugging of the screen. Be sure to run with fresh fuel mix and to shake the container thoroughly each time just before filling the tank to prevent oil starvation. Hope this helps!

using good quality 2 stroke oil use ratio 50:1

that is 20 mils of oil per 1 litre of petrol that you mix

put oil in can 1st then add petrol and give good shake

so if mixing 5 litres pour in 100 mils of 2 stroke oil and add 5 litres of fuel only

cheers hope it helps

Thank You for using FixYa.

Bring it back to your dealer.Did you mix the gas and oil correctly? Did you leave gas in it for more then a month? Have clean fresh gas? Flood it?

Fuel ratio 50:1 = 1gal premium/2.6oz quality 2-cycle engine oil
Fuel/Oil Mixture

1. Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 2gal premium/8oz chainsaw 2-cycle engine oil - used for many years) and finally the last 5 (±) years 50:1 (1gal premium/2.6oz Stihl 2-cycle engine oil)
2. Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few weeks. Anything over 1.5 months old use up in a 4 cycle engine. HTH
