You also want to look for one that’s easy to install. There’s no reason why there should be too much difficulty in installing a gas cap cover. Installation can create some unnecessary issues and even impact the quality of the product if not done properly. Even if the instructions are lacking, it should never be difficult to have a gap cap cover installed properly. 

Proper Functioning

It’s also important to make sure that your gap cap cover functions properly. What this entails is making sure the door operates smoothly, with a simple locking mechanism if that’s included. Additionally, you don’t want to have screws that are the wrong size or a cap that doesn’t fit into its spot perfectly.

What Purpose Does a Gas Cap Cover Serve?

So, why are gas cap covers so important? Here are a few reasons you need a good one for your vehicle:

Prevent Fuel Theft

A gas cap will always serve as additional protection from gas theft. Whether or not you live in an area where you’re at high risk, fuel cost makes fuel an asset you don’t want to take any chances with. A proper gas cap cover can make sure you never have to worry about someone unexpectedly stealing any of your fuel.

Avoid Maintenance Problems

If a gas cap is not functioning correctly, then you may run into minor maintenance problems. Sometimes a check engine light can appear if your gas cap has worn down over time, and a quick fix can make sure you don’t run into any other issues while also helping you identify why the check engine light was on in the first place.

Avoid the Smell of Fuel

Without a proper gas cap cover or with one that has a worn-down seal, you’ll eventually start to smell the fuel from your vehicle. Avoiding this issue is as simple as making sure the gas cap is on correctly. If that doesn’t help, it’s a clear indication you’ll need a new one to get rid of the smell.

What Size of Jeep Wrangler Gas Cap Cover Do I Need?

For the most part, the universal gas cap cover size will work for a Jeep Wrangler.  There are, however, a few things that you need to keep in mind. Certain options will distinguish between the two-door model and the four-door model. 

Many will be universal, but it’s important to look into that ahead of time. The only other issues may come from the screws or the pins about your vehicle. If that’s an issue, there’ll certainly be ways to remedy it by adjusting the screws or the pins accordingly.

Are All Jeep Wrangler Gas Cap Covers the Same?

There are important distinctions to consider when looking for the best gas cover for a Jeep Wrangler. One factor that will vary between gas caps is whether or not they’re locking. Having a locking gas cover may not be necessary for all, but it adds extra security for theft. Different gas cap covers will also have other installations. It’s important to note that, in some cases, you’ll need to drill to properly install it, while that won’t be necessary with others. Additionally, the way a gas cap cover looks can change a lot and allows you to find one that’s suited to your Jeep Wrangler.

Types of Jeep Wrangler Gas Cap Covers

Here are some common types of gas cap covers to help you decide which type is best for you:

Lock or No Lock Types

Jeep Wrangler gas cap covers are, for the most part, no locking gas cap covers. What this means is that they’ll install and close without an issue, but there’ll be no locking mechanism on the actual door. This gives you easier access and makes it less of a hassle any time you need to open it.

There are also locking gas cap covers. This type is less common, but in certain situations, it may be necessary. The locking mechanism is more important for anyone worried about fuel theft or any kind of damage being done. It may not be as convenient, but it can bring a lot of peace of mind for anyone concerned. 

Material Types

The materials will be the biggest thing to distinguish the types of gas covers. It’s important to know what kind of hazardous chemicals your gas cap cover may be exposed to, making sure you can find something resistant to whatever might break it down. Plastic covers can prove to be more problematic in certain situations. Additionally, you always want to look out for a black powder coating, which can help with the resistance you need.
