Jeep Wrangler Diesel Conversion Cost

If you are sick and tired of the ever-rising fuel and environmental pollution, it may be the right time to have a diesel engine conversion for your Wrangler.

Performing a diesel engine conversion on your Jeep Wrangler will let your standard diesel engine rely less on regular fuel and more on biomaterial, available in form of animal or plant oil.

By using this biodiesel, you will reduce environmental pollution while still saving some money. The first vehicle to utilize biodiesel appeared publicly in 2005.

Since then, the popularity of these environmental and budget-friendly vehicles has been on the rise. In this article, we will discuss the Jeep Wrangler diesel conversion cost and learn some biodiesel basics.

What is Biodiesel?

Biodiesel refers to fuel made from plant and animal oil as opposed to fossil fuels. Unlike fossil fuels, biodiesel is a clean-burning fuel made via a process known as transesterification.

Mixtures of biodiesel can work in a diesel engine for a cleaner environment and help you save a few bucks. Biodiesel usually comes in a percentage form; for instance, B50 biodiesel is a mixture of 50% of the regular fuel, and 50% is the amount of organic oil.

Is It Easy to Convert a Wrangler into Diesel?

Yes, it’s easy to convert a Jeep Wrangler into biodiesel. If you have finally made up your mind to go on the biodiesel route, you don’t have to worry as there are no significant mods required on the engine.

Most diesel engines on Jeep Wrangler can run efficiently on biodiesel as well. In fact, any diesel car is biodiesel ready. You don’t have to use the costly third-party kits in your engine.

However, some older vehicles may need a special filter to clean the biodiesel and make it ideal for the engine. There has been a hot debate surrounding biodiesel engines and whether they are actually beneficial in terms of mileage.

The truth is, biodiesel can save up to $2000 per year for Wrangler drivers. But the real advantage comes in the form of less environmental pollution.
