How do you not use oil injection on polaris jet ski?

To operate a Polaris jet ski without oil injection, you must manually mix oil with fuel in the correct ratio, typically 50:1 for two-stroke engines. First, drain the oil injection system and disconnect it to prevent leaks. Then, ensure you consistently mix the oil into the fuel tank each time you refuel, using a measuring container for accuracy. Regularly check for any signs of oil starvation in the engine to prevent damage.
