  • Written by: William Copper

The Gasoline Fuel Injector cleaning system by Liqui Moly is a very effective fuel injector cleaner and conditioner to use for both restoring, as well as preventing carbon build-up in your engine. Carbon build-up creates harmful deposits that can harm and interfere with your vehicle's engine and fuel injection performance, specifically the fuel injectors and parts that work together with them.

The Liqui Moly 2007 Jectron Gasoline Fuel Injector product belongs to a category of fuels injector cleaners - read HERE to learn more about how they generally work.

Liqui Moly 2007: Trusted Industrial and Aerodynamic Grade Ingredients

Originally developed in Germany, Liqui Moly 2007 relies on MoS2 (or Molybdenum disulfide) as one of its main ingredients. This is a high grade and non-organic metal that is developed in labs and used for vehicles from airplanes to watercraft. Manufacturers even use Molybdenum disulfide to create Kevlar and bullets. One of the most valuable characteristics of this metal is its ability to withstand extreme heat up to 350 Celsius (662 Fahrenheit). This is both very desirable and profitable for auto-cleaning products as it is one of the most effective ingredients available on the market. It safely removes carbon deposits while also preventing damage to your fuel injection system and engine.

This ingredient has been both tested and approved to function as a lubricant itself, so even if oil is low or being leaked there is a substantial amount of time available for your fuel system and engine to continue functioning. While this is not recommended, it illustrates the point of how powerful, clean, and purposeful Liqui Moly products are.

Liqui Moly 2007 Cleans Flushes and Restores Your Fuel injectors

Liqui Moly products have been available on the market for years and produce various solutions to meet the needs of treating, cleaning, and preventing harmful carbon and moisture deposits in your fuel injection system. The Liqui Moly 2037 Pro-Line Engine Flush is a prime example of this, as it ensures both rapid and gentle cleaning while remaining neutral and not harming any critical seals or moving parts in your fuel system or engine.

If you want to improve fuel economy, engine performance, or lower your pollutant emissions from your vehicle then the Liqui Moly 2001 Valve Clean is also a great product worth checking out. The Liqui Moly 2007 Fuel injection Cleaner is mechanic recommended and has been proven to improve emissions and meet smog requirements to improve both performance and ability to pass inspections. One of the greatest benefits of using the Liqui Moly 2007 Fuel Injector Cleaner is its ability to improve your systems combustion process, which in turn decreases engine hesitation, throttle, idling, and even stalling.

Advantages and disadvantages

  • This Fuel Injector Cleaner is effective at expelling moisture, carbon, and sulfur build-up which is harmful to both your fuel injection system and engine over time.
  • Liqui Moly Fuel Injector Cleaner can improve fuel economy (MPG) as well as engine response-time upon accelerating or idling.
  • For those with “sludge” in their oil or who don’t regularly change their oil as recommended it is possible to experience heavier clogging in both fuel injectors as well as engine oil with the use of this product. It’s recommended to have your vehicle professionally looked at before using the Liqui Moly fuel Injector Cleaner in such instances.
  • Not all vehicles will experience fuel efficiency, throttle response improvement, or overall engine performance if critical maintenance and necessary repair of engine or fuel system parts haven’t been done. Sometimes, pistons, carburetors, fuel pipes, and inlet valves become far too clogged from neglect or excessive use and in turn require professional cleaning or replacement.

Buy or not to buy ? Although many fuel injector cleaning products available on the market use MoS2 (or Molybdenum disulfide) ingredients and technology, Liqui Moly was one of it’s first developed. The Liqui Moly brand is well known in Germany, and also meets the government standards for a well-balanced, non-corrosive, effective cleaning system.
