How To Clean Old Diesel Fuel?

If possible, connect the gasoline reconditioner directly to the stored fuel storage. If you knew the relative volume of the old diesel fuel, you could add the ether or PRD-D straight to it. Per gallon of old diesel fuel, the ratio is 5.6 oz. ether or 0.0625 oz. PRD-D.

How do you clean dirty diesel fuel?

Fill the tank with a few gallons of water and a scouring medium, such as shards of safety glass or clean gravel. Add a liquid soap with petroleum-cutting characteristics, such as Dawn, Ajax, or Palmolive, and rapidly swish it around in the tank.

Is 10 year old diesel fuel still good?

It’s an age-old question for diesel truck drivers and anyone else who drives a diesel-powered vehicle. ‘Does diesel fuel have a shelf life?’ In actuality, there is no such thing as an expiration date for diesel, but the longer you store it, the worse it performs.

In reality, keeping diesel without properly treating it can cause a slew of problems, not just for the fuel but also for any vehicle into which you chose to put it later. We’ll go over exactly what happens to untreated diesel fuel when it’s stored for a long period, as well as how you may avoid these bad consequences by simply treating the diesel before it’s stored.

Diesel fuel’s performance deteriorates when it sits in storage for extended periods of time. When the fuel reaches the final stages of the process, we call it “diesel fuel gone bad.” It may be too late to save your stored diesel fuel if you notice these things occurring to it. However, there are a few things you can do to extend its life, which we’ll go into later.

  • As a result of being exposed to environmental variables, chain reactions occur: Light, water, and heat are the most prevalent environmental variables that have a negative impact on diesel fuel. If the diesel fuel is stored in a location where any of these things might affect it, the molecules in the fuel will produce chain reactions that will cause the fuel to slowly but steadily change from an oil to a varnish.
  • The gasoline darkens, and the gums get swollen: As a result of the chain reactions that occur between environmental variables and the molecules of diesel fuel, the fuel thickens and darkens, turning into more of a gum or sludge.

This process alters the molecular structure of diesel fuel, and because most modern diesel fuels do not contain the same amount of sulfur as older diesel fuels, bacteria begin to thrive in the fuel, forming biomass. This can result in acids that completely degrade the fuel over time.

  • The sludgy fuel won’t burn properly, resulting in black smoke: This thicker, darker dieselfuel won’t run as smoothly as a diesel fuel that hasn’t been influenced by external factors, resulting in black smoke and engine sputtering, which is never good for your car.
  • Internal vehicle damage due to lubricity: Because this diesel fuel no longer has the lubricity it once did, the acidic nature and thickness of the fuel will begin to negatively affect the fuel pump, diesel injectors, and engine, and you may not be able to start your engine if the problem is severe enough.

You may be wondering if there is any solution that will allow you to keep diesel fuel without it becoming a sludgy mess now that you know what it means when you hear it has gone bad.

The solution is significantly more straightforward than you might have assumed. You can ensure that your stored diesel fuel is safe at all times by using a diesel fuel stabilizer. Although there are numerous brands and formulations to pick from, we recommend Opti-Lube, which is the world’s #1 rated additive that more than doubles the shelf life of diesel fuel.

Despite the fact that diesel fuel does not have a specific expiration date, the performance of stored fuel might be harmed over time if improper storage and additives are not used. If you intend on storing fuel or not driving your truck over the winter, it’s important to use a reliable additive like Opti-Lube and take precautions before it’s too late.

We at Gem State Diesel understand the damage that gummed-up diesel fuel can cause to a vehicle, which is why we’ve decided to offer this knowledge and show you how we maintain our fuel working at its best no matter what. After all, it’s always better to be cautious than sorry, especially when dealing with something as precious and impressive as a diesel engine.

Can you clean diesel fuel?

With BG Products’ Inject-A-Flush technology, you can remove diesel deposits and get back on the road in 45 minutes. The complete diesel fuel injection system is cleaned in minutes by the BG Fuel Injector Cleaning Service.

What will dissolve diesel sludge?

Technol 246 from Dieselcraft is a fuel additive that penetrates and dissolves diesel sludge buildups in diesel fuel tanks to eliminate filter blockage issues.

Diesel sludge, also known as tank contamination, is an algae-like substance in which cells attach to one another on the tank surface or at the fuel water interface. When a vehicle is fueled, the sludge settles to the bottom of the tank and can clog filters.

A shell of extracellular polymeric substance surrounds these biological structures, protecting the bacteria from biocides and most other chemicals. Technol 246 disperses the sludge into smaller particles that flow through filters and nozzles without clogging or causing damage.

According to Dieselcraft, the cleaned-up fuel will emit less NOx, carbon monoxide, and particulate matter. Poor combustion produces black smoke, which is removed, preventing further biological growth and increasing fuel economy.

According to Dieselcraft, normal treatment costs are around 2 cents per gallon of fuel.

8 ounce bottles, 1 gallon, 5 gallon, and 55 gallon containers of Technol 246 are available. A self-contained tip and measuring bottle are included in the 1 gallon container. 8 ounces of Technol 246 will treat up to 275 gallons of gasoline, and 1 gallon of additive will treat up to 4,000 gallons of fuel, according to Dieselcraft.

Does old diesel fuel go bad?

According to studies, diesel fuel #2 becomes polluted and degrades within 28 days of being stored. Diesel fuel can only be stored for 6 to 12 months on average, while under ideal conditions it can last up to a year. In general, to extend the life of stored diesel fuel quality, it should be:

The term “diesel” is used in NFPA 110 “1.5 to 2 years of storage life.” According to the Standard, “Tanks should be sized so that gasoline is utilized within the storage life of the tank, or provisions should be provided to replace stale fuel with fresh fuel.” A-5-9, NFPA 110

Does diesel fuel expire?

Petrol becomes stale faster than diesel; contaminants and moisture in the tank can cause the fuel to become sticky if left in the tank for longer than a few months. Diesel, on the other hand, is less refined and more greasy, so it can last for several years. If you’re storing your car or lawnmower for an extended amount of time, chemical stabilisers are available to assist preserve the gasoline.

Is diesel fuel good after 2 years?

So, under these circumstances, how long does diesel fuel last? “Diesel fuel can be stored for 6 to 1 year without substantial fuel degradation if kept clean, cold, and dry,” according to Exxon. Diesel fuel can be stored for more than a year under specific conditions, according to Chevron:

  • Second, acceptable fuel quality and stability were obtained by using additives such as biocides, stabilizers, and additive packages that promote lubricity, improve the Cetane number, and offer detergents to keep fuel systems clean.
  • Finally, the fuel was tested on a regular basis, maintained, and polished as needed using portable filters.

As a result, the answer to the question “how long does diesel fuel last” is “it depends.” However, with good fuel stability achieved by correct storage and the use of diesel fuel treatments such as Diesel STA-BIL, you can combat fuel degradation for a long time while keeping expenses low and under control.

What is the storage life of diesel fuel?

In temperatures of 85 degrees, diesel fuel can last for 6 to 12 months. The fuel will then start to react with the oxygen in the tank. Diesel may become sticky as a result of this interaction. If diesel turns sticky, it can block fuel filters, causing engine problems. The sticky fuel will not burn properly, resulting in a film of soot and carbon on the engine’s inside. One possibility is to apply oxidation-resisting stability treatments.

Degradation of diesel fuel can also be caused by other sources. Fungus can grow in the presence of water in the fuel. Fungi can produce organic chemicals that break down diesel molecules. The gumming process can be accelerated by high temperatures. When metals like zinc and copper come into contact with diesel fuel, they can trigger a chemical reaction. Certain chemicals have been shown to hasten the aging process.
