Why is my cart fuel consumption so high recently?

My EZGO golf cart, which has always been a model of fuel efficiency, has suddenly started drinking fuel like there’s no tomorrow. It’s getting to the point where I’m considering taking out a second mortgage just to keep it running for my daily rounds. This spike in fuel consumption is not only hitting my wallet hard but also has me worried about potential damage to my cart. Has anyone else run into this problem?


I ran into something similar not too long ago with my cart. For me, it turned out to be a clogged air filter that was the culprit. Swapped it out for a new one and boom, problem solved. It was an easy fix, took no more than 15 minutes, and cost about $30 for the new filter.

While you’re at it, giving the carburetor a good clean and checking for leaks could also turn up some benefits. Hope this gets you back on the course without the extra fuel stops!

Solution 1: Replace Worn Piston Rings

  • Number of Users Helped: 5
  • Approx. Cost (USD): $150
  • Approx. Time Needed (Minutes): 120

Detailed Steps:

  1. Safety First: Ensure the cart is off and securely parked. Disconnect the battery to prevent any accidental starts.
  2. Access the Engine: Remove the engine cover and carefully take out the spark plug to prevent any damage.
  3. Removing Old Rings: Use a piston ring compressor tool to carefully remove the old piston rings. This might require you to take the piston out of the cylinder, so proceed with caution.
  4. Clean and Prepare: With the old rings out, take this opportunity to clean the piston grooves thoroughly. Any debris left behind can affect the seating of the new rings.
  5. Install New Rings: Carefully install the new piston rings, ensuring they’re properly seated in the grooves. Pay attention to the manufacturer’s specifications for orientation.
  6. Reassemble and Test: Put everything back together, reconnect the battery, and start the engine. Listen for smooth operation and monitor for any smoke from the exhaust.

Personal Experience:

A fellow cart owner noticed their cart was leaving oil spots where it was parked and found oil in the air filter housing. After some investigation, they discovered the piston rings were worn out. Replacing them not only stopped the oil leak but also significantly improved fuel efficiency.

Expert Tip:

Regularly check your engine’s oil level and quality. Dark, dirty oil or a significant drop in oil level can indicate worn piston rings. Early detection can save you from more extensive engine damage.

Solution 2: Adjust Oil Levels for Lifted Carts

  • Number of Users Helped: 3
  • Approx. Cost (USD): $0 (unless you need to add or remove oil)
  • Approx. Time Needed (Minutes): 10

Detailed Steps:

  1. Level Ground: Park your cart on a level surface to ensure an accurate oil level reading.
  2. Check Oil Level: Open the oil reservoir and use the dipstick to check the oil level. For lifted carts, the angle of the engine can cause inaccurate readings, so you may need to adjust your method.
  3. Adjust Accordingly: If the oil level is too high, drain the excess oil. If too low, add the appropriate type of oil recommended by the manufacturer until you reach the correct level.
  4. Monitor Performance: After adjusting the oil level, take your cart for a test drive to monitor its performance and oil consumption.

Personal Experience:

One user found that after lifting their cart, the oil readings were consistently showing as overfilled, which led to excessive oil consumption and reduced fuel efficiency. Adjusting the oil level to account for the cart’s new angle resolved the issue.

Expert Tip:

Consider using a high-quality synthetic oil that can better withstand the operating conditions of a lifted cart. Synthetic oils offer better protection and can help improve overall engine efficiency.

Solution 3: Check for Fuel Leaks

  • Number of Users Helped: 2
  • Approx. Cost (USD): $20 (for replacement parts if needed)
  • Approx. Time Needed (Minutes): 30

Detailed Steps:

  1. Visual Inspection: Carefully inspect all fuel lines, connections, and the fuel tank for any signs of leakage. Look for wet spots, stains, or the smell of fuel.
  2. Tighten or Replace: If you find loose connections, tighten them securely. Replace any damaged lines or components immediately to prevent further leaks.
  3. Test Drive: After making repairs, take your cart for a test drive to ensure the issue is resolved. Pay attention to fuel consumption and any smell of leaking fuel.

Personal Experience:

A user noticed a faint smell of fuel and found a small but persistent leak in one of the fuel lines. Replacing the damaged line eliminated the leak and restored the cart’s fuel efficiency.

Expert Tip:

Regularly cleaning your cart, especially in and around the engine and fuel system, can make it easier to spot leaks early. Also, consider upgrading to higher quality fuel lines that are more resistant to wear and ethanol damage.
