Keeping track of how long your golf cart is in use is a convenient tool to pay off multiple ways. First, think about anything that comes down to golf cart use. Every wear and tear maintenance schedule is based on time. We recommend that you service your golf cart twice a year based on usage. It may be more; it could be less. The only way to know for sure is the E-Z-GO TXT Hour Meter Kit. Please keep track of exactly how long it's been since you last changed the oil. Any steps you can take to make sure your golf cart is getting the maintenance it needs is vital. The last thing you want is a blown-up golf cart because the oil was not changed enough.The golf cart hour meter kit is not a seer's crystal ball. When you hook it up, it will not be able to see into the past to tell you how long your golf cart has been on the road. This is a moving forward upgrade; another handy feature is in the re-sell value of the cart. If you install one of these right when you first get your golf cart, you can accurately tell the next owner how many hours you used it for.
