Gas-powered golf carts typically travel 75–240 miles per tank, depending on engine size (8–14 HP), fuel capacity (3–6 gallons), and terrain. Most utility models average 25–40 MPG under mixed driving. For example, a 6-gallon tank with 35 MPG efficiency provides 210 miles. Pro Tip: Avoid overloading—every 100 lbs reduces range by 8–12% due to increased fuel consumption.

What factors determine gas golf cart range?
Range hinges on three key variables: fuel tank capacity (3–6 gallons), engine efficiency (22–45 MPG), and load conditions. Yamaha’s 301cc engine consumes 0.3 gal/hour at 15 MPH, translating to ~50 MPG on flat terrain.
Mechanical factors like tire pressure and air filters critically impact efficiency—underinflated tires decrease MPG by 10–15%. Hilly terrain slashes range by 30–40% compared to flat courses. Real-world example: A Club Car Carryall 295 with a 5.5-gallon tank achieves 180 miles at 33 MPG, but only 110 miles when hauling 800 lbs uphill. Pro Tip: Upgrade to synthetic oil—it reduces engine friction, boosting MPG by 4–7%.
How does engine size affect fuel economy?
Larger engines (14 HP+) prioritize torque over efficiency, yielding 18–28 MPG, while 8–11 HP engines achieve 35–45 MPG. However, power directly impacts hill-climbing capability without RPM spikes.
A 400cc Kawasaki engine burns 0.45 gal/hour under load versus 0.25 gal/hour for 250cc models. But what if you need both power and efficiency? Select variable-speed governors—they maintain optimal RPMs across terrains. For instance, E-Z Go’s Fleet Elite balances 11 HP output with 38 MPG efficiency through precision carburetion. Pro Tip: Annual valve adjustments restore 5–8% lost MPG from wear.
| Engine Size | MPG (Flat) | MPG (Hills) |
|---|---|---|
| 8 HP | 42–45 | 25–28 |
| 14 HP | 24–26 | 14–16 |
How do fuel types impact range?
Ethanol-blended fuels (E10) reduce range by 6–8% versus pure gasoline due to lower energy density. Methanol-modified fuels exacerbate corrosion, potentially clogging fuel lines and filters.
Non-ethanol 87-octane gasoline contains ~114,000 BTU/gal versus E10’s 110,000 BTU/gal—a 3.5% energy deficit. Over 10 tanks, this equates to 25 lost miles. Real-world test: A Honda-powered cart traveled 192 miles on ethanol-free gas versus 178 miles on E10. Pro Tip: Use fuel stabilizers if storing carts >30 days—phase separation in ethanol blends can permanently damage engines.

FAQs
Yes—installing high-flow air filters and low-resistance exhausts improves MPG by 12–15%. However, avoid performance carburetors—they often sacrifice efficiency for power.
How does cold weather affect fuel range?
Below 40°F, gasoline density increases, reducing combustion efficiency. Expect 15–20% range loss—pre-warm engines with block heaters to mitigate this.
