a two-cycle engine derives all of its lubrication from the pre-mix oil that is mixed with the gasoline. this is done either in the raw fuel or via an oil injection system. if you have an oil injection system there is nothing wrong with putting straight gas into the tank as long as the oil reservoir contains a lubricant designed for an oil injection system. however if you do not have a oil injection system putting straight gasoline into the engine will more than likey cause the engine to lose lubrication and either rapidly wear down any internal components or in the worst case seize the engine solid

What is the oil to gas ratio for 4 cycle engine?

A four cycle engine does not use a gas/oil mixture. The oil is in the crankcase and the gas goes in the gas tank. If you put oil in the gas on a 4 cycle engine it will run poorly and smoke a lot.


How do you tell if a lawn mower is a gas only or a gas oil engine?

A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).


What is 2-cycle engine oil?

Two cycle engine oil is made to be mixed with gasoline. This mixture may range from 1 part oil to 20 parts gas (1/30) to 1/50. Its usually written on the gas cap of the 2 cycle engine. This oil is the only lubrication a 2 cycle engine receives, so it is very important. NEVER run a 2 cycle engine on straight gas because permanent engine damage will occur.


What do you do if you put straight gas in a two cycle engine by mistake?

it will explode mix some thin oil in with the gas, this will lubricate the cylinder walls and will stop it from seizing up. that is how we ran the old two stroke motorcycles.


Why does a two cycle engine require more oil than a 4 cycle engine?

Because a 2 Cycle Engine burns the oil in the gas, and in a 4 cycle engine, it sits in the oil pan, and it isn't supposed to burn it at all.


Do you mix gas for a 1977 xr75 dirt bike?

No. This is a 4 cycle motor that runs on straight petrol (gas).


Can a gas go straight from a gas to a liquid?

Yes, in fact it happens in the water cycle. Condensation is gas turning into liquid. Any state of matter changing to any state is possible if the conditions are right (boiling point, properties, freezing point,etc.)
