Can you use 30 weight oil in a 2 stroke engine safely?

It is generally not recommended to use 30 weight oil in a 2 stroke engine. Two-stroke engines require oil that is specifically formulated for their unique design and operating characteristics. 30 weight oil is typically too thick and can cause problems with lubrication and engine performance. Additionally, using the wrong type of oil can void the warranty on your engine. If you are unsure about the best type of oil to use in your 2 stroke engine, it is best to consult your engine's owner's manual or a qualified mechanic.
