Diesel Engine Deposits - Affecting Efficiency & Performance

What are Diesel Deposits?


Diesel engines are very popular today, partly because of their fuel efficiency/ MPG and because they have greater torque. Also, turbocharged diesel engines can have similar or even better performances than their petrol rivals.  Although diesel and petrol are made from the same crude raw material they have different characteristics which makes diesel and petrol powered engines operate very differently.

Problems with Diesel Deposits -

Diesel engines suffer the problem of carbon deposits forming inside the engine. The most common type of deposits are those around the fuel injectors. Every diesel engine experiences this problem and it occurs in parallel with engine use - so basically the more miles on a diesel engine the greater the problem of deposit formation.  As the deposits begin to develop and accumulate around the injectors fuel consumption will increase and the engine will lose power.  The vehicle will become more expensive to run as it loses efficiency and guzzles fuel at a greater rate. 
It will also see a marked reduction in power as the engine's performance is impacted. Studies have shown that a brand new diesel car with a 324 all-wheel horsepower on average loses 7 horsepower over the first 5,000 miles of its life and a further 12 hp over the next 5,000 miles.

What's the Solution?

A diesel engine should be treated and fuel injectors cleaned to eliminate this accumulative carbon deposit build up.  There are a number of ways you can clean your fuel injectors:

  • Ultrasonic Waves - one approach is to take your car to a professional garage and have Ultrasonic Waves clean away the debris. This is a good option but it is expensive.  As well as being costly, it may not remove all the deposits successfully. 
  • Clean Manually - another way is to dis-assemble the fuel injectors and clean manually.  This is a technical job, and should only be done by a qualified professional that knows exactly what they are doing.  It is a thorough approach but again it is expensive and very time consuming.  
  • Diesel Treatment - the best and most practical method to cleaning the fuel injectors is to use an additive called diesel treatment. These chemicals are added to the fuel and while the engine is running they circulate, clean the engine and remove the debris that has deposited in the fuel injectors.  It is a very cost effective and easily applied solution.

Try using a Diesel Treatment solution now to ensure your vehicle is running at optimum efficiency and performance and that the engine is clear of carbon deposits.

Additional benefits of adding a diesel additive include:

  1. Protection for Entire Fuel System - it will clean the hoses, pipes and fuel pump. This will help protect the fuel system giving it increased resistance to corrosion and deposit formation.
  2. Eliminate Black Smoke -  it can help eliminate black exhaust smoke.  Black smoke is usually caused by bad fuel or problematic fuel system and a build up of carbon in the system. This diesel additive can eliminate this issue as it cleans the whole fuel system. 
  3. Reduce Noise - it can help reduce engine noise as the engine recovers efficient operation.
  4. Increase Engine Life - as it provides an added amount of lubrication to the fuel the engine can last longer.

The old way of displacing deposits was thrash it down the motorway 70 of course!

I add in a diesel treatment after every 10,000km. Keeps the engine in good order. There’s been no problems with loss of efficiency. Works well for my wheels!
