Fuel Additives Solutions

Engine Stress and Heat

The Issue: Diesel fuel is used in engines to fuel combustion and convert energy into motion. Modern diesel engines circulate the fuel from the fuel tank to the high pressure fuel rail and back to the fuel tank. During this process, the fuel is heated and placed under significant pressures, up to 40,000 psi. This stresses the fuel and has the potential to create carbon, soap and salt deposits on critical engine parts such as injectors and fuel pumps. This can cause wear and injector drive, which leads to over fueling and also causes a host of related issues from lost power and fuel economy to frequent DPF regenerations and soot in fuel filters, turbochargers, and EGR valves. These issues cost operators thousands of dollars in downtime, repairs and increased maintenance.

The Solution: LHT “Gold” Year Round Protection and Performance is specifically designed to address all the issues of modern fuel systems and return “Like-New” performance. Restoring lost fuel economy, and reducing premature fuel filter plugging, injector failures, fuel pump failures, frequent DPF re-gen, EGR valve, turbocharger coking and downtime.

Wax Build up

The Issue: Diesel fuel contains wax, which provides energy necessary for the engine to run. Without wax there is no energy in diesel fuel. During winter months outside air temperatures drop and cool the diesel. This cooling causes the wax to solidify and settle to the bottom of the tank. Left unchecked the wax will solidify, much like a candle. This can prevent the engine from starting or even shut it down without warning.

The Solution: EC-1 is a combination of additives that not only keeps the diesel liquid at low temperatures, but helps prevent icing and wax settling. Using modern polymer technology, EC-1 will arrest wax formation and keep diesel liquid at low temperatures. Cheap, low cost winter additives stop here. Keeping fuel liquid is only the first step in providing winter operability. Your customer demands service, and that requires your equipment to start and run. That is where EC-1 delivers. EC-1 contains two additional components that provide the peace of mind you demand. Diesel fuel contains small amounts of water, an as little as 50ppm of water can freeze at relatively warm temperatures causing filters to “ice” and fuel lines to plug, stopping operations. Wax is heavy and over extended shutdowns, like cold weekends, wax will settle to the bottom of the fuel tank. This is usually evident when the engine starts and soon after shuts down. The fuel in the tank is liquid, but the filters and fuel lines are plugged with wax. WASA or Wax Anti Settling Agents can keep this from stopping you in your tracks. You won’t know you need it until it’s too late. EC-1 has WASA that makes more than claims, it makes a difference!


Organisms are always present in fuel, and under the right conditions they will bloom; water, fuel and the absence of light provide conditions microbes love, and the food to thrive. Microbes produce acids & decompose fuel as they move through their life cycle. A significant volume of dead microbes, is referred to as “Sludge”. This sludge causes storage tan corrosion issues and contributes to equipment problems. Primarily filter plugging and internal engine corrosion.

The Solution: Fuel biocides are federally registered pesticides designed to kill microorganisms in fuel. The ones that work are not cheap, but are well worth the additional cost. Some “Biocides” on the market are cheap and simply remove water, temporarily creating a less than ideal environment, and only slowing microbial growth temporarily. Some biocides, if not used at the proper treat rate will also have poor results. Proper biocide and treatment regiments sterilize fuel tanks and keep microbial activity in check. Ask you LHT representative for more information if you see signs of microbial contamination.

Samples Tested Annually

Proper Tank Maintenance is the key to success

Innospec tests 4,000 fuel tanks for Bottom Sediment and Water (BS&W), annually
75% of the samples have BS&W present
50% of the samples with BS&W did not meet ASTM D975 specifications
1 out of every 5 fuel tanks sampled had heavy microbial contamination present
