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.

Is it bad to run a 2 stroke rich?

Can Running Rich Damage The Engine? Running rich will very rarely damage an engine. However, running too rich for too long can cause problems long-term that will affect performance and reliability. Rich jetting will foul a spark plug more easily.

HOW LONG CAN 2 stroke fuel be kept?

As for sealed containers it states: The storage life of petrol is one year when stored under shelter in a sealed container. Once a seal is broken the fuel has a storage life of six months at 20°C or three months at 30°C. As stated earlier, “fresh is best” so be sure to mix smaller batches more frequently.

Can I mix 2-stroke oils?
