JLM’s Extreme Clean’s thorough cleaning process restores the entire turbo and the diesel particulate filter, as well as the intake valves, EGR valve and injectors. First, the active components in JLM Diesel Extreme Clean efficiently remove the soot deposits from the parts of the fuel system and the engine. After cleaning, the parts are now lubricated and protected against oxidation and other deposits that could affect engine performance. Open the fuel cap and put the appropriate amount of additive in the tank (this varies depending on the product and the size of your fuel tank). From there, just fill up the tank with diesel! Not only will you get a clean fuel system, but you’ll get much better engine performance compared to most other fuel additives!

Liqui Moly Pro-Line Diesel Cleaner is a German product that does a great job at cleaning up diesel engines. It’s an extremely affordable product that improves your fuel efficiency and gives you a quiet ride.The only problem is that it only lasts about 1,500 miles. The difference is that Liqui Moly is a product they recommend to use to spot treat problems, and that’s why it fell down our list a bit. So, yeah, it’s a more affordable additive upfront, but if you’re not getting the results you’re expecting, you’ll need to add more, and then your savings are straight out the window. While BG 245 Premium Diesel Fuel System Cleaner might not be the biggest name in the industry, that doesn’t mean it’s not an excellent choice for your vehicle. For starters, it lasts up to 10,000-miles. That’s twice as long as the next closest product on our list.

But since it lasts twice as long, it’s not like you’re spending any more in the long run! BG 245 treats the entire fuel system, not just the injectors, giving you maximum results. You get improved fuel efficiency, better engine performance, improved cold starts, and more.Lucas Oil is one of the largest names in the additive industry, but that doesn’t mean they should be your go to. To be clear, they’re not a bad choice, but we don’t like that you start to notice performance drop-offs after just 1,500 miles. With Liqui Moly it can work that way, but that’s not what they made it for. And it’s for this reason alone it fell down to the bottom third of our list. It cleans the entire fuel system and improves engine performance, especially during cold starting conditions. It also improves engine emissions, which is a big deal if you need to go through annual inspections.
