Four-stroke Jet Skis use 10W-40 4-stroke marine engine oils. Kawasaki recommends using the Kawasaki Performance 4-Stroke 10W-40Jet Ski oil. But if this oil is not available you can also use other types of marine 4-stroke 10W-40 oils that meet the NMMA FC-W requirements.
Ever, can you use regular motor oil in a jet ski? Sure. There's really no reason you can't. Just keep an eye on your Jet Ski's engine oil levels, as you would normally, and follow the same maintenance schedule, changing the oil regularly as per your owner's manual. It is pretty common to run synthetic oils in your two-stroke motors, too.

Yamaha's Waverunners take home the trophy for the most reliable jet ski, but there are some good runner ups. Kawasaki and the now extinct Honda jet skis are both renowned for their dependability. The problem with Kawasaki is they aren't quite as dependable as a Yamaha, and their engines can be tricky to work on.
Why do Yamaha WaveRunners shoot water?
Two Reasons Why Jet Ski Shoot Water The first one is in order to help cool down the electric motor. The electric motor strives to draw water right into the duct below the machine, and also thrust it from the back.

On average a jet ski should have approximately 30 hours a year. Anything more than 30 hours per year is considered “high hours”. Most jet ski models have a lifespan of approximately 300 hours, but if properly maintained they can last much longer.
Due to their design, 2-stroke engines burn oil continuously along with the gas. This means 2-stroke engines don't have as efficient a lubrication system as 4-strokes, so their internals wear out much faster. Moreover, 2 stroke engines are more powerful and run at higher RPMs compared to 4-strokes.
