Previously, due to gasoline being cheap, many people used to ignore the importance of diesel engines. However, the rise in demand for gasoline has increased its price, and somewhat the market is reverting back to the use of diesel. Whoever drives a strong vehicle will always see diesel as the ideal option for their car instead of gasoline.

According to specialists, it is great to have a 3.6L V6 engine in a Jeep Wrangler. Sometimes, to become fuel efficient, car lovers install a 3.0L V6 engine; however, that doesn’t help much. Yes, a smaller engine will consume less power but the entire driving experience is affected.

Well, the deadly combination of a relatively smaller engine, diesel, and transmission will surely provide a good driving experience plus it will help the car to become fuel-efficient as well.

What are the 3 best diesel engine for jeep wrangler?

When we talk about diesel engines, there are only a handful of reliable companies which are producing the best quality engines.

Let’s discuss the 3 best diesel engine for jeep wrangler;

Mercedes Benz OM617

It would be unfair to the pioneer of luxurious cars to not include them in the list of best diesel engines. Mercedes Benz has been successful in producing quality diesel engines since the 1930s.

Mercedes Benz OM617 was found in the 60s and 70s 300-series cars and also collaborated in the Jeep community as well. The inline-five-cylinder engine was quite common in most of the Mercedes variants and later on, they turned those engines into turbo-charged. Well, the performance is not something excessively commendable except for the 120 horsepower.

Later in 1985, Mercedes was sensible enough to counter this mistake of their previous engine with an inline-six-cylinder engine. The performance of this variant was slightly better than the previous one as it produced 140 horsepower. However, it was not affordable to the mainstream audience.

No non-turbo engines would be included in the list if you wish to exchange the current engine with a diesel one. Well, it would not be worth it to get 79 horsepower instead of a powerpack engine.

Additional tuning can increase the power of an inline-five-cylinder engine. Nevertheless, the five-cylinder OM617 is quite long in size due to which it might be a task for the mechanic to do spacing accurately. This engine has a height of 27 inches so surely it would impose challenges for you.

When compared to its competitors, 3.0L is less expensive than them. However, purchasing one from the scrapyard might bring hurdles for you. Nonetheless, these engines are always appreciated for their miles and fuel average. According to experts, a car can run approximately 500,000 miles with these engines.

Moreover, they are easy to repair, unlike the modern-day Benz diesel engine. They don’t require any kinds of computers to get them installed in the Jeeps.

Volkswagen 1.9L TDI

This German company was not far behind in the race when we talk about diesel engines. However, Volkswagen also had to face its part of the struggle just like its cousin Mercedes Benz. Nevertheless, this is not the only diesel engine on the catalog of Volkswagen. There is another successful diesel engine 1.6L which is found quite easy to support Jeep Wrangler.

Volkswagen launched its first diesel engine back in 1996 in North America. Well, the market went crazy after its inauguration. A lot of car lovers wanted to swap their engines with this beast. However, the horsepower it provided is just 90 but turbocharged engines have provided a good life to the sporty sedans and Jeeps. Even if you compare it to today’s engine, it would meet the criteria and all standards.

On the other hand, there was one major complaint found in the 1.9L engine and that is the lack of power and efficiency. Nevertheless, the size and weight of the old 1.9L engine are slightly less when compared to the four-cylinder engines available in the market.

Cummins 4BT

When we discuss swapping diesel engines, the Cummins 4BT is quite common in the market. It can be found easily in the market. The Cummins 4BT engines are found perfect for Jeep Wranglers and FJ Cruiser.

This engine is 30 inches and only weighed 800 pounds. 4BT engines are providing a horsepower of 105. However, later models are even more powerful. They are providing a power of 170 horsepower. Unlike 4BTA engines, 4BT are easier to swap.

On the other hand, it might become a difficult task for you to place the 4BT engine in your Wrangler’s frame. Due to the availability of multiple conversion kits, the process of fitting becomes easy for the owner and the mechanic.

According to experts, before you make the final decision of swapping the engine, it would be great to take a test ride first. If you can easily survive with the noise and vibration in your car, a Cummins 4BT would be a good choice for you.

Conclusion

If you wish to just swap the engine to save fuel, this should not be your only motivation. As you need to know that the conversion rate might be $5,000 and that might affect your savings surely.

Another vital factor is the packaging of the engine. Sometimes, the packaging is left with some holes and that might create a problem for you in near future. So, before you invest in swapping engines, do thorough research and understand your needs.
