Wranglers are notoriously known for their terrible gas mileage on highways and in the city. Due to its big, cubic shape, the Jeep Wrangler is generally not the most aerodynamic compact SUV on the market today, but they are one of the most fun! Many of the mods that we add to our Jeeps create even more inefficiencies as they pertain to your fuel, forcing you to take more trips to the pump. Don’t fret though- you’re not out of luck! Keep these tips in mind to keep your fuel spending down when driving your Wrangler.
Get a new or used Jeep Wrangler JL
While this may not be practical for most owners, those who are in the market for another Jeep should heavily consider a JL for a gas mileage boost straight from the factory. The current generation of Jeeps can get up to 10 miles per gallon over its predecessors, making it the most fuel-efficient Jeep Wrangler ever. In addition to improved gas mileage, Wranglers released after 2018 include improved infotainment systems, surround sound speakers, and other state-of-the-art technology. Jeep introduced a diesel engine to the Wrangler line in 2020, making it one of the only models in its class to have one. The 2020 Jeep Wrangler EcoDiesel sees about 29 miles per gallon on the highway and 22 in the city, for a combined driving mileage of 25 miles per gallon.
Installing New Hood Latches
While driving your Wrangler, you’ll probably notice your hood flapping up and down at high speeds. This is known as hood flutter. When this happens, air is going underneath the hood and getting trapped within the engine area. With nowhere to go, this negatively impacts the aerodynamics of the vehicle and will hurt your gas mileage profoundly. The quick, easy fix for this is installing new hood latches to your Jeep. They are relatively easy to install and inexpensive to purchase. Replacing the Wrangler’s stock hood latches with aftermarket variants will have a big positive impact on your fuel efficiency.
Maintain your vehicle and engine
Performing regular maintenance is a must for all vehicle owners, however, keeping up with your Jeep Wrangler’s will make it runner smoother, faster, and much more efficiently. Making sure your spark plugs and spark plug wires are intact, your air filters have been replaced, and your carbon intake is clean of gunk and debris ensures your Wrangler runs smoothly and will get you a bump in miles per gallon. New intake and exhaust systems will also help your engine breathes easier, giving you about an extra mile per gallon or two. Overall, keeping up with the regular maintenance schedule of your Jeep Wrangler will provide you a multitude of benefits and should be performed as necessary.
Avoid loading your Jeep with heavy items
Many people overlook the impact keeping everyday items in your Jeep Wrangler can have on the fuel efficiency you’ll get on your daily drive. Everything you keep inside your vehicle will hurt your gas mileage, no matter how big or small. One simple thing you can do to take a couple pounds off your Jeep is removing your spare tire. Many have reported receiving an extra mile per gallon from this simple delete, but it may not be practical for those who regularly go off-road. When going on trips, consider renting a utility trailer to keep all your gear in. This will ensure that you receive optimum fuel efficiency throughout the trip, and you’ll be able to travel at higher speeds as well, saving you time on the trip and at the pump.
Our beloved Wranglers are super fun vehicles, but boy are they gas guzzlers! Luckily, there are a ton of ways to help relieve the weight and lack of aerodynamics in your Jeep Wrangler. This guide should provide a great starting to point to different methods for increasing the gas mileage on your Jeep.
