If I had to summarize this Lucas Fuel Treatment review in a single sentence, it would be this:

This stuff just doesn’t mess around.

Arguably one of the best products on the market, this Lucas Oil upper cylinder lubricant works wonders with your fuel injection system.

While there might be products out there that perform specific cleaning tasks a tad bit better, the Lucas Fuel Treatment presents an amazing checklist of features:

The great people at Lucas Oil have produced a really good product here. It is extremely versatile and suitable for just about any engine out there, perfect for easy to perform, time-saving maintenance. When you look at this product a little closer, it’s easy to see why it’s so good.

The product is designed to be extremely safe to use and thus contains no solvents, alcohol, kerosene, diesel fuel or anything else that could damage engine parts. It consists of various super slick oils and additives which are designed to lubricate the various systems it flows through, as-well as helping break up gunk in the injectors. This allows the fuel to burn more effectively within the engine, reducing fuel consumption. It is also able to replace the benefits of leaded fuel without the negative side-effects, so it’s great for use in older vehicles that require leaded fuel. And because it also neutralizes the harmful effects of low sulfur diesel fuel, it is similarly great for use in any diesel engine.

Here’s a great video showcasing how this additive increased MPG by about 20%, now that’s amazing!

One of the methods that this product uses to achieve these results has got to do with replacing polymers. Basically, most low sulfur diesel fuels and gasolines have had their polymers removed to comply with the government regulations for reducing fuel fumes in the air. While the goal was achieved, this also caused the fuel to become less lubricated and thus less efficient. We have cleaner air, but less useful gasoline.

Lucas Fuel Injector Cleaner replaces those lost polymers with a specific concentrate that has none of the negative side-effects of the polymers.

Instead, the concentrate works as a lubricant that makes the fuel slicker and more efficient and powerful. Not only will the increased fuel efficiency result in lowered fuel consumption, it also increases power while reducing emissions. Slicker fuel also helps to lubricate the cylinder walls and rings, prolonging their life-span. And not only that, intake valves, pumps, carburetors, injectors and compression rings are also lubricated. An absolute must for rotary engines.

Any way you look at it, this Lucas fuel injector cleaner is a winning product.  And don’t worry about shelf life, it lasts just about indefinitely.


How to use?

  • Pour Lucas Fuel Treatment directly into the fuel tank.
  • Recommended dosage is 2-3 ounces of Fuel Treatment per 10 gallons of fuel.
  • Exceeding the recommended dosage is not harmful to your vehicle (but why be wasteful).



The Lucas Fuel Injector Cleaner is without a doubt one of the best products on the market. No wonder it is our top pick when it comes to injector cleaners. Many cleaners make aggressive claims about their effectiveness, but most fail to deliver.

Not the case with this Lucas Oil product. Whether you are looking to clean your gasoline or diesel engines because of clogging symptoms or simply looking for a fuel additive to give your engine a little oomph, this is the product to go for.

Pick the suitable container size for the amount of fuel you want to treat and enjoy the benefits!
