Is Redex Diesel Cleaner Any Good?

For a few months, we’ve been using Redex Diesel System Cleaner in our 100k-mile Ford C-Max to test if it helps performance and efficiency. Is it effective?

In our 100,000-mile Ford C-Max, we started using Redex Diesel System Cleaner to check if Redex’s claims of greater economy and smoother running were true.

However, since we initially started utilizing it, we’ve had one inquiry from a number of readers:

Does redex diesel system cleaner really work?

Over the last few months, we haven’t noticed any significant changes when utilizing Redex. However, the concept of keeping a system clean is still a good one. Redex offers preventative steps for keeping fuel tanks clean and can help you save money on gas in the long run. We enjoy the notion of utilizing a cleaner on a regular basis to keep the vehicle in good shape. After all, we clean and polish the bodywork, so why not the engine as well?

Is Redex any good for diesel engines?

Yes, Redex can be used in any internal combustion engine. Our fuel additives work in cars, vans, motorcycles, tractors, and anything else with a gasoline or diesel engine, even hybrids.

What does Redex do to a diesel engine?

In my Mazda MX-5, I just ended a three-month trial of Redex fuel system additives to see whether I could notice any improvement in performance or see a substantial difference in fuel economy.

Since May, I’ve been personally noting down the litres added and kilometers covered rather than relying on the car’s trip computer when filling up the tank, as well as putting a dose of Redex to the tank.

As I’ve mentioned in earlier reports, I’ve been utilizing a fuel system cleanser rather of an octane booster as a gasoline additive. The idea isn’t to change standard petrol into premium unleaded by increasing the car’s octane number, but rather to thoroughly clean all of the tiny pipelines and injectors so they can function without becoming clogged.

There’s a lot of combustion going on under your hood, given that your engine produces dozens of explosions every second. Any time you burn a fuel, you’re going to get deposits and debris. When you burn a log in a fireplace, the ash that develops is a good example. These deposits can be miniscule in some cases, such as in your car’s engine, but the idea remains the same. These deposits accumulate over time and impair your capacity to burn the gasoline properly.

The Redex fuel system cleansers are designed to remove deposits from the fuel injection system and keep it clean. The fuel will burn cleaner as a result, giving you improved performance and fuel economy because the engine will be running more efficiently.

As I previously stated, this is not a controlled laboratory test, but rather a real-world trial that gives a good indicator of what a driver can expect in normal life.

How often should I use Redex diesel?

Is it necessary to use Redex DPF Cleaner on a regular basis? Redex DPF Cleaner should be used every second or third tank of gas, especially if you drive short distances or do a lot of stop-and-go driving in a city.

What is the best diesel engine cleaner?

While the XADO Xtreme Cleaner Heavy-Duty Semi Truck Diesel Treatment is near the bottom of our list, it doesn’t mean it’s not effective. The truth is that it only went so far because its application is so constrained.

This diesel fuel additive is only for semi-trucks. It’s a super concentrated compound that processes enormous amounts of fuel efficiently.

So, unless you have a 130-gallon or greater fuel tank, you should avoid it. Don’t try to figure out the appropriate ratio for a much smaller engine by measuring it out because even a little too much can be disastrous.

Does Redex clean fuel filter?

If your diesel automobile has a DPF filter and you do a lot of slow stop-start driving in town, mix a shot of Redex DPF Cleaner with Diesel System Cleaner in the fuel tank to prevent filter clogs. Our unique mixture cleans and reactivates the DPF, removing soot without the need for expensive repairs.

Are fuel additives a waste of money?

A friend of mine swears by the fuel additives that claim to improve gas mileage. They’re all worthless in my opinion. Am I correct?

It’s understandable why consumers would want to believe that such a product works. Wouldn’t it be great if you could add an additive to your gas tank or take a tablet that would dramatically improve your car’s gas mileage at each fill-up? However, both commercial and homebrewed fuel additives are virtually always a waste of money. These additives will not boost your car’s mpg, with one important exception (read on). If you really want to save money on petrol, you should buy a fuel-efficient vehicle and drive it carefully.

Will Redex clean my diesel injectors?

The Redex Diesel Advanced Fuel System Cleaner cleans fuel injectors thoroughly to improve fuel economy and performance. DPF cleaning is included to clean and eliminate soot blockages in your vehicle’s particulate filter.
