The Best Turbo Cleaner For Diesel & Petrol: Additive & Spray

By on 19 August 2020 / Leave a comment Updated on: 17th February 2021

Turbochargers, the automotive worlds current solution to all customer needs. Need more power or torque from an engine? Turbocharger. Require lower emissions and a smaller engine size? Turbocharger. The efficiency, power and emissions standards required from modern engines have led the majority of vehicle manufacturers to offer nearly all product lines with turbo-enhanced combustion engines. They enable small engines to make large power outputs, without the extra emissions and size restraints imposed by a larger engine or one with a greater cylinder count. This is something that is becoming more relevant by the day, in an industry obsessed with environmental factors and carbon emissions.

A common issue however, that does crop up for modern turbocharged vehicles, is clogging of the turbocharger and its internal components, particularly on diesel engines. Exhaust gasses (that pass through the turbocharger) contain unburnt fuel and soot, carried out of the engine after it’s combustion cycle. This dirty air, which is particularly foul in diesel-engined vehicles, will deposit onto components within the turbo and lead to improper function, damage and even failure in extreme circumstances.

Removal and replacement of turbocharger components could be one option to solve the issues, though expect a bill running into thousands rather than hundreds of pounds. For a simple, cost-effective solution, that you can implement at home, look no further than one of the turbo cleaning products below.

The Types of Turbo Cleaner

Turbo cleaning products are found in many varieties, the most common and widely available being pour-in or spray additives. Both can be used at home, without lots of specialist tools or knowledge. This can potentially save owners thousands on garage services, without the car leaving the driveway.

Turbo Cleaning Pour-in Fuel Additive

Pour-in turbo cleaners work by adding the contents into the fuel tank, to mix with the diesel inside. This mixture will pass through the fuel system and engine before finding its way to the turbo. Improvement in performance and fuel economy should be noticeable almost immediately, as well as preventing issues with further build up if applied at regular intervals, as recommended by the manufacturers.

These additives are super easy to implement, requiring no special tools or knowledge and very little time. It is important though to ensure a full or nearly full tank of fuel in the vehicle before use. The car then needs to be taken for a good drive, ensuring the product has made its way through the turbo before full benefits can be realised.

Key points for pour-in additive turbo cleaners:

  • Extremely easy to use
  • Low outlay
  • Great for those with no tools and/ or no DIY experience
  • Less direct application when compared to spray products
  • Only suitable for diesel vehicles

Turbo Cleaning Spray

Spray cleaners work slightly differently to pour-in additives, in that they are not added into the fuel tank but directly into the turbo via the inlet pipework. These solutions are sprayed through the inlet hose, after the filter and sensors, allowing it direct access to the turbocharger.

This approach should ensure that the product can set to work quickly and have an increased cleaning effect for the turbocharger. These additional steps however, will increase the amount of time needed to implement. Spray additives also require the user to have at least a couple of basic tools and a little knowledge of basic mechanics or a knowledgeable friend.

Key points for spray turbo cleaners:

  • Very direct application to the turbocharger
  • Only requires basic tools and knowledge
  • Longer process compared to using a pour-in additive
  • Products to suit petrol and diesel vehicles available

Revive is a manufacturer that operates a little differently to those featured above. Unlike competitors they do not have wide range of additive lines, instead they focus purely on their internal engine component cleaning products. Their attention to detail in this sector shows, with them being the only brand listed that offers separate petrol and diesel offerings, both with the same aim but with different construction in order to satisfy specific engine conditions.

Both formulas contain active ingredients that are said to bind to dirt and soot particles, removing them as the air passes through the turbocharger. The tiny particles can pass safely through the exhaust and catalytic convertor, ensuring no further blockages or damage is caused. Revive promises that the solution will allow full function of the moving turbocharger vanes, as well as having positive cleaning effects across the whole of the engine. This, they promise, will give restored performance and increased longevity for the entire engine.

Revive’s water-based formula is said to be bio-degradable and non-toxic, really emphasising the companies focus on environmental impact and sustainability. Simply sprayed into the inlet, after the air filter, the solution will pass through the turbo and engine to remove all build ups, though this may require multiple applications. Thanks to the large quantity provided, this product should support multiple uses.


  • Manufacturer specialising in engine cleaning products
  • Focus on environmental impact
  • Separate petrol and diesel formulas to ensure optimum results
  • Binds to dirt and removes from the turbocharger
  • Safe formula, non-toxic and non-flammable
  • Large quantity of product, suitable for multiple vehicles


  • More expensive than competitive spray additives

In Conclusion

Simple to apply and massive in potential gains, turbo cleaners are a product that is becoming ever more relevant in today’s modern era of turbocharged engines. Nearly all performance cars of the last 5 years have come fitted with a turbo, while you will struggle to find a diesel vehicle without one made in the last decade. Trying one of these inexpensive turbo cleaning products could not only save you thousands in garage repair bills, but should give any turbo-powered vehicle an entirely new lease on life.

Think of it this way. You will happily spend a little extra for more data on your phone, a nicer bottle of wine and that slightly plusher sofa. Turbo cleaners simply aim to improve the driving experience of your vehicle. They will maintain its efficiency and reliability, whilst also saving you from expensive repairs in the future. For such a small outlay, there really is a lot to gain and not a lot to lose.
