For diesel vehicle owners, maximising engine performance, fuel economy, and longevity is crucial. One of the most effective ways to achieve this is by using a cetane booster. Products like JLM Cetane Booster offer a powerful and reliable way to enhance your diesel engine’s efficiency while also delivering a range of benefits for your diesel-powered vehicle.

This guide will walk you through what a cetane booster does, why it’s beneficial, and how to use it correctly to get the best results.

What is a cetane booster and what does it do?

A cetane booster is a diesel fuel additive that increases a vehicle’s cetane number, which is an important measure of fuel combustion quality. A higher cetane number leads to faster and more complete combustion in diesel engines. Additional benefits of using a cetane booster include:

  • Smoother engine operation
  • Improved power delivery
  • Reduced emissions
  • Easier cold starts
  • Reduced engine knock and vibration
  • Protected engine components

JLM Cetane Booster, for example, is a powerful option, formulated to boost cetane levels by up to 5 points. With a recommended dosage of 250ml per 40 to 60 litres of diesel, this diesel cetane booster delivers noticeable improvements in engine performance.

A cetane booster has been added to the tank and is helping to make combustion more efficient.

Do cetane boosters work?

Yes, cetane boosters do work, especially when used with low-quality diesel (with a low cetane number) or in challenging operating conditions. Users consistently report improved engine responsiveness, smoother idle, and reduced exhaust smoke. When selecting the best cetane booster, JLM stands out for its reliability, ease of use, and proven results.

JLM Cetane Booster is not only safe but also highly beneficial for diesel engines. It improves fuel combustion, reduces wear and tear on engine components, and lowers the risk of deposits forming in the fuel injectors. Additionally, it reduces harmful emissions, making it environmentally friendly. By boosting performance and efficiency, it helps prolong the life of your engine.

When to use a cetane booster

You should use a diesel cetane booster like JLM in the following situations:

  1. Low-quality diesel fuel: Offsets poor fuel quality and improves combustion.
  2. Cold weather conditions: Higher cetane fuel starts easier and runs smoother in winter.
  3. Performance demands: Boosts output when towing, racing, or carrying heavy loads.
  4. Older diesel engines: Helps restore efficiency and reduce smoke in aging vehicles.
  5. Long-distance travel: Maintains fuel efficiency and consistent engine stability over long hauls.

How to use JLM Cetane Booster effectively

How much JLM Cetane Booster to use

Using the correct amount is key to effectiveness. For JLM Cetane Booster:

  • Use 250ml for every 40 to 60 litres of diesel.
  • Always check your fuel tank size before adding.
  • Do not overdose—more is not better and can be wasteful.

Using JLM Cetane Booster

  1. Measure the right amount: Stick to the recommended dosage (250ml for every 40 to 60 litres of diesel)
  2. Add before refueling: Shake the can and pour its contents into the tank first.
  3. Refuel your vehicle: Fill the tank with diesel immediately after adding the booster for better mixing.
  4. Drive normally: The additive works as you drive, optimising combustion from the start.

For full system cleaning, consider pairing with a diesel system cleaner, ensuring to never use multiple additives simultaneously.
