Is it worth using a diesel fuel additive in winter?

In order to keep your diesel engine performing at its highest level, using a quality diesel fuel additive is essential.

1. When should I use diesel additive?

This depends on a number of factors, including the age of your vehicle, your driving style, and any specific issues you may be experiencing. However, here are some key indicators that indicate it's time to use a diesel additive:

a) Deteriorated engine performance:
If you notice a drop in power, increased fuel consumption, or erratic idling, it may be time to use a diesel fuel additive to revitalize your diesel engine.

b) Subzero degrees or difficult starting:
When outside temperatures drop, diesel fuel can freeze or form deposits in the fuel system, causing cold start problems. A diesel fuel additive can prevent these problems.

c) Emission of black smoke:
If you notice an excessive amount of black smoke coming from the exhaust gas of a diesel vehicle, this may indicate incomplete combustion of the fuel. A diesel fuel additive can improve the combustion quality of diesel fuel.

 

2. Recommended frequency of use

The frequency of use of diesel additive depends on several factors, including the selected processing method and driving style. Here are some general guidelines.

a) Spray cleaners:
Injector cleaners are designed to remove carbon and deposits that build up over time. Use them every 3,000 to 10,000 kilometers to keep injectors clean and engine performance optimal.

Winter fuel additives prevent diesel fuel from freezing

b) Antigel:
Use an antifreeze additive - antigel when the temperature drops below zero degrees Celsius. This improves the flow of diesel fuel at low temperatures and prevents the formation of paraffin crystals that can be harmful to your vehicle. Diesel fuel (shown on the left in the illustration) in which paraffin crystals have formed in cold temperatures clogs the diesel fuel filter, preventing the engine from starting.

c) Diesel fuel improvers:
To improve engine performance, solve fuel quality problems, or simply prepare your vehicle for the next inspection, use a diesel fuel enhancement additive. Specially designed to reduce vehicle pollutant emissions.

By regularly using diesel additives, you can enjoy a number of benefits, including:

• Better fuel economy.
• Optimum engine performance.
• Reduced pollutant emissions.
• Reduced long-term maintenance costs.

In conclusion, treating your diesel fuel with an additive will help keep your engine in top condition and extend its life. To get the most out of them, follow the recommendations for each product and your situation.
