Readers ask: Why Add Oil To Fuel?

What happens when fuel mixes with oil?

Gas can be very expensive so it’s not ideal to just waste it. Another reason this is a problem is because when gas and oil mix, this causes the oil to lose its ability to lubricate the engine parts. When oil can’t do its job properly, these parts start to create a lot of friction and then the engine could overheat.

How long will a 2 stroke run without oil?

The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing – and in most cases, it’s a lot quicker than that.
