Gas golf carts can take regular unleaded gasoline, however, to reduce the progression of build up, ethanol free gasoline is preferable. Aside from that, gas golf carts are practically self-sustainable. What we recommend outside of any unusual performance issues is routine annual maintenance for your golf cart to stay healthy. Keep in mind that new E-Z-GO and Yamaha gas golf carts come with “break in” oil, and you may need to change it after the first 10 hours of use. From there, it’s smooth sailing!
