4 Best Fuel Additives for Diesel Cars 2018

Diesel Fuel Additives are an addition to your cars fuel that provide many benefits such as performance, cleaner running and more efficient operation. Since the addition of the DPF (Diesel Particulate Filter) which removes  soot from the exhaust, diesel cars have become a lot cleaner. Older diesel cars can be seen chucking out black soot from the exhaust but these are slowly becoming extinct.

There used to be a real dislike around diesel cars with car owners thinking they are dirty and indeed slow. However, newer diesel provide low end torque to push you back into your seat and power to match, which keep up with their petrol competitors. For me, the diesel revolution began with the Germans producing large 3 litre diesel engines matched with a huge turbo. These diesel engines produce big performance figures but also great miles per gallon figures.

Diesel engines require more assistance in terms of requiring additives compared to petrol/gasoline engines. This is down to the fact that gasoline is high quality fuel that has been refined further than diesel fuel has. Diesel fuel is often stored for later use and is known as the “business fuel” for shipping and other large scale businesses. When diesel is left stored for months on end, the fuel can develop problems that require additives to fix.

Without using high quality diesel fuel, irregular servicing and no additives, your diesel car can suffer problems such as:

  • Hard cold starts
  • Injector failure from carbon build up
  • DPF issues
  • Running rough at low RPM and idle
  • Lots of black smoke on acceleration
  • Poor fuel economy
  • Cetane improver

Sometimes it is hard to find a garage that sells high quality fuel, therefore using fuel additives will assist with a healthy running diesel engines. After having to change 6 injectors in my 320CDi Mercedes E Class, I have been using high quality fuel as well as additives to ensure smooth efficient running. Miles Per Gallon has improved on long runs, easy starts in the morning and I can sleep at night knowing my injectors are going to stay clean. Below are the best diesel fuel additives on the market today.

What fuel additive is best for a diesel car?

The Schaeffer diesel is more targeted for the freezing conditions over winter, but as an overall diesel fuel additive, the Hot Shot’s Secret P040432Z is my choice. The reason being is that you are able to use it rarely (Advised once every 6 months) rather than every time you fill up. This means that its great value for money and its is highly rated on Amazon with various people giving their real world stories of the product.

By using high quality fuel and fuel additives here and there, you will be able to see results within a few miles. After having using my 320CDi Mercedes in lots of standstill traffic on cold winter mornings, the fuel injectors started to breakdown and the car ran very rough. Since replacing the injectors and using high quality fuel, the car runs much smoother and I will continue to use diesel additives to ensure the long term use of the fuel pumps and injectors.
