If you drive a diesel-powered car or truck from 2009 or newer, you most likely have a Diesel Particulate Filter (DPF) installed as part of the exhaust system. The DPF is designed to improve air quality by filtering out harmful particles normally found in diesel exhaust. The particles then accumulate on the DPF until it is cleaned. If you let your DPF get too dirty, it can cause permanent damage. So what do you need to do to keep it clean?
How Does a DPF Work?
Myth: You need to idle a diesel engine for 5 minutes or more in the morning
One thing you may want to consider is driving a vehicle that is lighter in weight...perhaps making the switch from a four-wheel-drive truck to a two-wheel-drive. The goal is to use as little power as possible, and a two-wheel-drive vehicle can give you around a 20 percent increase in fuel economy.
Electric Fans Many have determined that running electric fans while driving your diesel in the city and on the freeway can contribute up to an additional two miles per gallon. Definitely enough to give it a try.
Increasing timing and rail pressure
The reason why these two circumstances are problematic for DPFs is because the engine isn't working hard enough to generate the power necessary for regeneration to occur. Most vehicles with DPF systems installed will signal a warning if the DPF is 80% blocked.
If you see this warning, you can usually resolve the problem by driving 50 mph or more for at least 45 minutes. By working the engine harder, you will be able to generate the power and heat necessary for regeneration to occur.
Myth: Diesel is dirtier than gasoline
One thing that can have a major impact on miles per gallon is gearing. You can consider adding a gear vendors overdrive on your truck can add as much as four or five miles per gallon. EGT Gauge
Using your EGT gauge can be helpful. They are a good indicator of the amount of fuel your diesel engine is consuming. Tire Pressure. It is recommended to run your tires at 80psi to help you improve your fuel economy. This may affect the ride of your truck, but the trade off of savings can be really nice. Acceleration
You should watch your acceleration carefully. Avoiding accelerating too quickly, and accelerating then stopping can really help to increase the miles per gallon you so desperately need.

About the Author:
At the time the California Air Resource Board's diesel emissions regulations first came out, Michael Schwartz, now President of FleetServ, started getting calls from panicked Fleet Managers looking for straight-forward information and compliance assistance. While FleetServ (formerly known as ACT Compliance) was originally formed to meet this need, over time it has evolved into much more.
