If using an oil other than McCulloch, the ratio is 40:1. Brand Specific McCulloch two cycle oil is 20:1.
If u buy an oil called "Motul"...the normal mixture is 50 or 60 to1 ratio...the leaner u run the oil the less chance a fouled plug. DO NOT TRY THIS MIXTURE WITH A CHEAP OIL...U WILL REGRET IT. Motul is very good stuff...I ran it at a 60 to 1 with 110 octane fuel in a 2000 YZ250.
50:1 ratio
Try 1.5 turns out on the mixture screw for an initial setting.
The 110 model, 9.8 hp Mercury outboard requires a 50:1 ratio, one pint of 2 cycle oil to six gallons of fuel.
It is 110/1.
The manufacturer recommends 50:1 mixture roughly 16 oz for 6 gallons
ratio of 110 miles to 130 miles 11 :13
110 to 1 is one possible answer.
110/58 = 55/29
0.110089
The sound pressure level in decibels depends on the distance to the chainsaw. In 1 m distance we can get 110 dB. In 10 meters distance we get 90 dB. So keep off the noise maker.
Multiply both numbers of the ratio, 10/11, by any non-zero number. You will have an equivalent ratio.
