If you use Stihl genuine two stroke mix, then the ratio is 50:1 eg 500ml to 25 litres fuel
Use regular Stihl 2 cycle oil. You mix it 50:1.
I use 30-1 in mine.
. What is the correct gas/oil ratio for STIHL products?A. When using STIHL branded Two Cycle Mix Oil, a 50:1 ratio (1 gallon of gasoline to 2.6 oz of STIHL 2 Cycle Oil). STIHL has Two Cycle Oil in easy to use bottles that are pre-measured for easy mixing with regular grade gasoline that has a minimum rating of 89 octane. Refer to your owner manual.
MS stands for 'Magnum Series' of Stihl chainsaws, their moderate to average use line.ACTUALLY: PER ANDREAS STIHL HIMSELF: IT'S "MOTO SAGEN"...GERMAN FOR "POWER-SAW".
use newer synthetic oil. it covers a broad range of fuel/oil ratios with one mix. it will allow you to use one fuel mix for all your 2cycle equipment. not marine though.
I use 40:1 mixed with high quality 2-stroke oil. I have used this mix in 1000s of chainsaws without any problem. http://store.chainsawr.com/
You can use several length bars on this saw. It looks like it came from the factory with a 20" bar.
They use a concrete saw, a gas powered saw, such as Stihl 14", Echo, Wacker. If your lucky, in your area you can buy the 45 degree blocks
Mostly no, oil for lubrication is within a separate sump that is filled and changed separately. The exception is the Stihl 4-Mix engine which does use mixed fuel just as a two-stroke would. It traps oil in the bottom end of the engine to lubricate the bearings and uses the oil within the mist of the intake charge to lubricate the upper end and valve train.
it is a 4 stroke so unleaded.
There is no fuel mix needed they are 4 stroke air cooled. Just use straight gas. dbg
