Servicing your engine is something that needs to be done based on how much it gets run. Customers hate hearing that, and we get it. There is nothing in the golf cart world like the sticker they put on your car's windshield at the lube shop telling you what mileage to return. Chiefly because there is no odometer on the vast majority of caddies on the market. Outside of an hour meter, which a lot of times are more trouble than they are worth, the best way to get your cart on a good service schedule is to tune it up once for every season of use. If you only use it in the winter, you only need to tune it up once annually. Just don't forget parts like the Yamaha Oil Drain Plug Washer.This golf cart washer is not a hard part to install. There is safety in numbers as with anything on your coach, or anything for that matter. Have a friend close by to spot for you.
