It's important to use a good quality oil designed for premix use, such as those sold by Kawasaki or Yamalube. Avoid using automotive-grade oil, as this can damage your jet ski's engine.
To mix your fuel and oil, you can use a measuring cup or a graduated cylinder. Just be sure to measure accurately, as too much oil can cause your engine to run rich, while too little oil can cause it to run lean.
Once you have mixed your fuel and oil, shake it thoroughly to ensure that it is well-mixed. You should then pour it into your jet ski's fuel tank and be ready to hit the water!
