This would depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic). I personally ride a 2001 Kawasaki KDX200 that I run Yamalube 2R at 36:1 with no problems. Although synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.
14 to 1
there is no ratio they are oil injected there is no ratio they are oil injected
It is when the "correct" air to fuel ratio is used to completely burn the fuel in question in an internal combustion engine. If exactly the correct amount of air is used this is called the stoichiometric mix.
The correct fuel oil ratio is 50/1.
11:3
32:1 ratio
50:1
A 1989 model, 70 hp Johnson outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
60:32
13:1
approximately 14.7:1
It depends on what year it is.
