Redex diesel additives clean your engine's fuel system, removing performance-robbing deposits from fuel injectors and the Diesel Particulate Filter (DPF) to improve fuel economy, restore power, lower emissions, and keep your engine running smoothly and efficiently. They work by dissolving buildup, allowing fuel to burn more effectively, and reducing soot in the DPF, preventing costly repairs and boosting responsiveness, especially in older diesel cars.
Yes. It's a good idea to give your engine a deep clean on the inside every now and then, as this will make sure it's always running efficiently. The Redex Advanced Fuel System Cleaner products do just that.
Regular use of Redex helps to:
Typically, we recommend adding a shot of Diesel System Cleaner to your car each time you fill up with fuel. This will help you get optimal results to keep your car running at its best. Failing that, a shot of Redex once a month can help to maintain the engine during day-to-day driving conditions.
Redex Diesel System Cleaner is a fuel additive specially developed to reduce emissions and restore performance in your fuel system. It removes deposits that build up on fuel injectors, and can be used safely in all diesel cars including hybrid.
With that in mind, let's take a look at the most common symptoms that might indicate that a diesel injector is failing.
STP 5-in-1 Diesel Cleaner
If you want to give your diesel engine a total blitz, the STP 5-in-1 additive is an excellent option. Pour it into your fuel tank and it'll start removing buildups from your engine.
As much as fuel injector cleaners are safe when used appropriately, there are conditions that they cause complications.
There has been no noticeable difference in performance, and I suspect you'd need a laboratory to really show any improvement. In the variable nature of the real world, and in a well-maintained modern car, I couldn't detect any difference.
Add a dose of Petrol System Cleaner. The lines on the side of the bottle will show you each shot. Replace the cap and carry on your day. Redex Petrol System Cleaner gets to work instantly, working its way through the fuel system to remove dirt and deposits from the injectors.
Signs Your Ford Might Benefit From Fuel Additives
These include a noticeable decrease in fuel economy, rough idling, or hesitation during acceleration. Engine knocking or pinging, especially when using the recommended fuel grade, can also suggest the need for a fuel system cleaning.
The easiest and cheapest method of DPF filter cleaning is by driving the vehicle for a long-distance at high revs per minute. Doing this increases the heat of the exhaust and burns the soot blocking the DPF filter. It's best to drive on a motorway or A road where you can keep the vehicle at a consistent speed.
You can use Redex DPF Cleaner either when the warning light comes on to clear the blockage, or during normal driving to prevent problems occurring. It's easy to use- simply pour into your fuel tank.
At Cost Effective Maintenance, we recommend the CRD Fuel Enhancer—a premium diesel injector cleaner trusted by Australian drivers. This powerful formula goes beyond just cleaning; it also enhances diesel fuel quality and provides lubrication to protect the entire fuel system.
Fuel additives are ideal for keeping a filter unclogged from the inside during use and can typically be poured into the filter without removal.
It allows you to control what you're putting in to your car. If you add a shot of Redex every tank, you know that you're adding the right mixture of fuel additives to clean your engine, giving you better fuel economy and reducing emissions.
We reckon Redex works out at about 5p extra on every litre of fuel used, but that's less than the fuel saving we've experienced. But as 5p a litre is about half the extra of 'Premium' fuel, it's pretty cost-effective as a way of getting your fuel system to work more effectively.
Opti-Lube XPD is the best diesel fuel additive for everyday use. Opti-Lube XPD is a proven diesel fuel additive. This additive made its mark years ago by ranking the highest in a fuel additive study.
The reason for this is that the DPF can only burn off the build-up of soot and regenerate during long periods of high-speed driving. That being said, using a diesel fuel additive with a DPF cleaner can allow the DPF to be cleaned, even at lower speeds.
6 Signs Your Diesel Vehicle's DPF Needs Cleaning
Recognizing the Telltale Signs of Clogged Fuel Injectors
Key Takeaways. Quality products with strong detergents mean does fuel injector cleaner work is often yes for mild deposits, but not for serious mechanical faults. Lab research and mechanic experience show do fuel system cleaners work best as preventive maintenance along with good fuel and regular servicing.
The worst things for a diesel engine involve neglecting maintenance (especially oil/filters), using poor fuel quality, allowing low fuel levels, overloading/lugging the engine, and not letting it warm up/cool down properly, all leading to contamination, excessive wear, turbo damage, and injector/pump failure due to high pressures and sensitive components. Contaminated fuel (water, dirt, high sulfur) is especially damaging, corroding parts and clogging filters in these high-pressure systems.
Cleaning the engine main body
Use compressed air to blow away loose dirt from the exterior of the engine. Your workshop vacuum cleaner will do the trick if it has a small hose extension. Spray engine cleaner on your dirty engine, but stay away from exposed electrical components.
Use a biocide or chemicals that kill bacteria and other contaminants.
