How do you tell if a 2-stroke is running lean or rich?

keeping the engine under a light load (you will only be opening the throttle to 1/2 or so) If the needle is set too rich you will hear a sputtering like the choke is on and the acceleration will be slow. If the clip position is too lean the engine will sound quiet and have a “dead” feeling possibly hesitating.

Mixing them will not improve the performance or efficiency of your engine in any way. Nor will mixing improve the oil performance, either. This is illustrated by these two equally important points: Adding synthetic oil to regular motor oil will not enhance the regular oil.

Will an extra half quart of oil hurt my engine?

An extra half a quart of oil in your crankcase is not going to do any harm to the engine. If the crankcase were seriously overfilled — say, more than a quart — then the spinning crankshaft could come into contact with the liquid oil, and churn it up. Then you’d get oil foam.

Does oil last longer with highway driving?

The quality of the oil isn’t measured; instead, a calculation is made based on your driving patterns. So, if you take a lot of short trips, the light might come on after driving only 5,000 miles. If you do a lot of highway driving, which causes less wear on the engine, it might come on after 6,700 miles or more.

How long can synthetic oil sit in an engine?

Oil can sit in an engine for no more than six months, give or take. While the shelf life of unused motor oil is between five and eight years, the actual lifespan of motor oil inside an unused engine is about six months. Old oil can dry out—and dry oil cannot lubricate your engine safely.
