Yes you can, and it improves throtle response immensely... happy Riding
Fuel is fuel. The fuel only changes when you add 2 stroke oil to it. You can burn it in a 4 stroke engine, might smoke some, but it is not recommended for your normal outing.
Fuel to oil ratio for a 8 hp Mercury, 2 stroke model, is 50:1. This is roughly measured out at one pint of 2 stroke oil, to six gallons of fuel.
No 4 stroke motors use 91 octain fuel or better. You only mix oil & gas for 2 stroke motors.
Four stroke engines use an oil sump, and do not need to have oil mixed into their fuel.
You need to define what your use of the oil will be. If you mean adding oil to the fuel, you do not need to do this on an 4 stroke motor. Or maybe you mean engine oil, or maybe transmission oil?
100 to 1 100 mls of oil to 5 litres of fuel, use premuim fuel and good quality 2 stroke oil
Use no oil additive. It is a waste of money and might actually do harm.
The only way you don't mix fuel with your oil in a two stroke motor is if you have an oil reservoir with an injector separate from your gas tank. Otherwise mix fuel with your gas if it is a two stroke engine.
this varies from 2 stroke oil to 2 stroke oil, but 32:1 is the recommended optimum ratio for lubrication vs. performance. ONLY USE 2 stroke premix style oil for any CR 2 stroke model Honda.
the first motorcycle used coal for its steam powered engine but now they use gas that doesnt completely answer the ? so with all honesty yes. in fact, all motorcycles use gas and oil. 4 strokes use fuel to run, and oil in the engine, where as a 2 stroke requires gas/2 stroke oil mix for fuel, and oil for the engine.
100 ml of oil for 5 litres of fuel 50 ml of oil for 2.5 litres of fuel
The 1976 model, 115 hp Mercury outboard, requires a 50:1 fuel to 2 cycle oil ratio. This is roughly one pint of 2 cycle oil, to six gallons of fuel. The use of 4 stroke type motor oil is not recommended, nor intended, for fuel / oil mix.
