Ford Diesel Air Filter Replacement

Is your Ford diesel struggling up inclines, or unable to tow heavy loads anymore? This is one of the classic Ford diesel performance warning signs. Fortunately, not all causes are expensive or difficult to fix. One of the most common culprits is a clogged or damaged air filter.

Regular Ford diesel air filter replacement, typically every 30,000 miles (or sooner in dusty conditions) is essential to maintaining smooth operation.

Ford Diesel Fuel Injector Failure 

Diesel injector issues not only reduce Ford Power Stroke performance but can also cause serious engine damage if ignored. Are you experiencing some of the following symptoms?

  • Excessive smoke from the exhaust
  • Rough idling and hard starting
  • Decreased fuel efficiency or loss of power

If you notice these signs of poor diesel performance, it’s time to have your injectors inspected by a qualified mechanic. For more information on the causes and potential solutions to faulty diesel injectors, take a look at this article.

Diesel injector designs vary between different Powerstroke diesel engines, and so does their pricing. A single diesel injector kit can sometimes cost a few hundred dollars, and this includes the high-pressure steel pipe and retaining bolts.

Can I Replace The Diesel Injectors Myself?

It is possible to replace your diesel Ford’s injectors yourself, but it requires advanced mechanical know-how, and a good set of tools to tackle the job. In most cases, it is best to have your diesel injectors replaced by a reputable shop.

Ford Cetane Boosters

Cetane boosters help raise the cetane level of diesel fuel, which allows your diesel Ford to run at its best.


“In some areas diesel Cetane levels are below Ford’s minimum recommended levels, and a Cetane booster is a quick and effective way to boost performance.”


If you struggle to start your truck in cold mornings, are getting poor fuel economy, or find overall performance to be poor, then it may be time for a Cetane booster.

Find out more about the benefits of Cetane boosters in this breakdown.

How Much Do Cetane Boosters Cost?

Cetane booster pricing varies on the strength, brand and container size. A 1-gallon bottle of cetane booster that promises to boost cetane levels by 4-8 points can cost over $100, and typically treats up to 1000 gallons of diesel.

Where Should I Buy A Cetane Booster?

Look for specialists and online retailers that offer products of this type. As always, avoid unknown brand names and products that offer benefits that seem too good to be true.

Can I Use Cetane Boosters Myself?

Yes. Cetane boosters can simply be poured into your diesel fuel tank. Make sure you mix the diesel and cetane in the recommended ratios to get the best results.

Diesel Fuel Filter And Water Separator Maintenance

Depending on your Ford diesel model, you may have a water separator and fuel filter designed to keep moisture and contaminants out of your fuel system.

If your fuel filter becomes saturated with water it can lead to fuel line corrosion, a damaged fuel pump, and eventual engine damage. Always replace your fuel filter and water separator at the recommended intervals and especially if you see a ‘water in fuel’ warning or notice poor performance.
