At DPF Fixer, we regularly see motorists with increased fuel use that is often caused by a clogged Diesel Particulate Filter (DPF). Over time, these filters get clogged, especially if you’re mostly doing short, low-speed trips that don’t allow the DPF to regenerate properly, affecting their function of filtering out harmful soot and particles from your vehicle’s exhaust.
This blockage restricts the flow of exhaust gases, causing the engine to work harder to push them out. This increase in backpressure means the engine is under more strain, leading to higher fuel consumption.
Some common signs of a blocked DPF:
Increased Fuel Consumption: A big indicator is noticing a drop in how many miles you get per gallon as the engine compensates by burning more fuel to maintain performance.
Reduced Power and Acceleration: Acceleration feel less responsive leading to a sluggish driving experience. That loss in power is directly tied to wasted fuel.
Frequent Regeneration Cycles: Your car might try to burn off excess soot by initiating more regeneration cycles, which in turn consumes more fuel.
Ignoring these warning signs only makes things worse. Left unchecked, a clogged DPF can lead to engine damage, pushing fuel efficiency down even further.
The Everyday Impact on Fuel Efficiency
Some customers have reported a significant drop in their fuel economy, sometimes as much as 15-20%. One driver reported going from 50 to 40 miles per gallon within a few months. Once we performed a professional cleaning, their fuel efficiency bounced back, saving them a small fortune in the long run.
For diesel drivers who regularly commute or take long trips, these numbers add up quickly into a big expense. A clean DPF can make the difference between a smooth, efficient drive and a fuel-wasting grind.
The Benefits of Professional DPF Cleaning on Fuel Economy
Professional DPF cleaning, restores your DPF to near-new condition. At DPF Fixer, we free up the exhaust system, reducing backpressure and allowing your engine to run at peak efficiency again by removing the soot and ash deposits. You’ll see a noticeable improvement in fuel consumption.
Regular DPF cleaning also extends the life of your engine, helping you avoid more costly repairs and breakdowns down the line. A clean DPF ensures that your car isn’t working harder than it needs to, keeping your fuel bills in check and your engine purring.
How to Keep Your DPF Clean to Maximise Fuel Use
Once your DPF is cleaned, you can help improve your diesel consumption through good maintenance. Here are a few tips to help you out:
Take Longer Drives: Try to take longer journeys at higher speeds to burn off soot since short trips don’t allow the DPF to regenerate.
Stick to Regular Maintenance: Having your DPF checked and cleaned regularly is a no-brainer if you want to avoid fuel wastage. Don’t wait until you see the warning light.
Use the Right Fuel: High-quality diesel can reduce soot buildup, helping your DPF last longer between cleanings.
We strongly recommend scheduling DPF cleaning as part of your regular vehicle maintenance to help get the most out of every tank of fuel.
Conclusion
Keeping your DPF clean ensures that your car runs efficiently, saving you money on fuel and avoiding more significant repairs down the road. If you’ve noticed an increase in fuel consumption, don’t wait—get in touch with us today to schedule a DPF check.
