AMSOIL Diesel Cold Flow (ACF) combats diesel fuel gelling by improving diesel cold-flow ability. It is formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures. Diesel Cold Flow is formulated for a broad range of diesel fuels, including biodiesel and #1 and #2 ultra-low-sulfur diesel (ULSD). Unlike all-in-one fuel additives that may sacrifice performance in specific areas in the name of convenience, AMSOIL Diesel Cold Flow makes no sacrifices; it is purpose-built for diesel owners who demand maximum results.

Reduces Need for #1 Diesel Fuel
Using #1 diesel fuel is one traditional solution to cold-weather diesel fuel problems. While #1 diesel fuel has an advantage in low-temperature operability, the energy content of #1 diesel fuel is about 95 percent that of #2 diesel fuel, resulting in reduced fuel economy and less horsepower. In addition, the kerosene used in #1 diesel fuel provides less lubrication for the fuel pump and fuel injectors, increasing the likelihood for wear. AMSOIL Diesel Cold Flow minimizes the need for blending standard #2 diesel fuel with lower-quality #1 diesel fuel, helping to maintain fuel economy and keep engines functioning normally.

Helps Prevent Gelling
As the temperature drops, the wax naturally found in diesel fuel begins to crystallize. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clog the fuel filter and starve the engine of fuel, preventing it from starting. While low-quality fuels may form wax crystals in temperatures as warm as 40ºF (4ºC), most fuels have a cloud point near 32ºF (0ºC). The point at which the crystals clog the fuel filter is known as the cold filter-plugging point (CFPP). AMSOIL Diesel Cold Flow lowers the CFPP by up to 20ºF (15ºC) in ULSD.

Additional Benefits
AMSOIL Diesel Cold Flow uses a jet-fuel-type deicer that disperses water to control ice formation throughout the fuel system. It inhibits wax crystal formation and can improve diesel pour point as much as 58ºF (32ºC), allowing fuel to flow to the engine more easily and improving diesel engine reliability in cold temperatures.

  • Disperses water to control ice formation & prevent gelling
  • Improves diesel cold flow ability by up to 20°F (15°C)
  • Enhances engine reliability in cold temperatures
  • Improves startability
  • Reduces downtime & maintenance costs

AMSOIL Diesel Cold Flow is specially formulated for improving the flow of diesel fuel, helping to maintain the integrity of fuel and prevent the clogging of filters and injectors. It is excellent for use with diesel fuels, heating oils and kerosene.

Add before filling tank. AMSOIL Diesel Cold Flow must be added at temperatures above the diesel fuel cloud point (the temperature at which wax begins to crystallize). It will not reverse gel or wax crystals once formed. Do not store at temperatures below 0ºF (-18ºC). If product freezes, rewarm and shake thoroughly to restore normal functionality. Excellent for use with AMSOIL Cetane Boost and AMSOIL Diesel Injector Clean.

AMSOIL Gasoline Additives Help Restore Engine Performance


Summer brings family vacations, trips to the lake, ATV excursions and other activities that rely on gasoline. In order to ensure vehicles, boats, ATVs and other recreational equipment are reliable and get the most for your money at the pump, it’s important to periodically perform some simple fuel-system maintenance.


A vehicle’s engine demonstrates its best efficiency and performance when it’s new. Over time, gasoline-generated deposits form on fuel injectors and intake valves and in the combustion chamber. Additionally, higher ethanol fuels can cause varnish and gum to form on internal engine components. While all gasoline is mandated to contain a lowest additive concentration (LAC) to help keep engines clean and control emissions, most gasoline lacks sufficient high-quality additives to minimize deposits and varnish. The low levels of detergent additives in modern gasoline allow deposits and impurities to build up on critical fuel-system components and can lead to a range of problems, including the following:

  • Decreased fuel economy
  • Decreased power and poor throttle response
  • Failed emissions tests
  • Poor drivability (surging, hesitation, stalling, rough idle)
  • Engine knock
  • Difficult starts


AMSOIL offers two products to help keep gasoline engines running their best: P.i. Performance Improver and Quickshot.



P.i. is the premium choice for maximizing fuel economy in passenger-car applications. It is an effective one-tank, total fuel system cleaner that provides maximum deposit clean-up to help maintain peak efficiency, power and drivability. When deposits form on injectors, the spray pattern becomes irregular and the volume of fuel delivered is negatively affected. Inadequate fuel delivery paired with an uneven spray pattern results in decreased engine efficiency, power and fuel economy. P.i. effectively cleans port and direct fuel injectors to restore f

uel delivery volume and regular fuel spray pattern.


P.i. also quickly cleans intake valve deposits to improve airflow and rebalance air-fuel intake. Deposits on the intake valves restrict airflow and have a tendency to absorb and release fuel, creating an imbalanced air-fuel mixture that results in lost engine power, increased emissions, poor engine efficiency and potential valve failure.


P.i. cleans deposits in the combustion chamber to regulate engine noise, temperature and emissions. Combustion-chamber deposits can act as a secondary ignition source that can lead to reduced power, increased engine temperature and engine damage from engine knock. Additionally, deposits that flake off and aren’t expelled through the exhaust valve remain on the valve seat when the valve closes and cause compression loss, difficult starting, rough idle, increased emissions and a possible burned exhaust valve.



Fights Ethanol problems in small engines, stabilizes fuel and restores performance.

Fights Ethanol problems in small engines, stabilizes fuel and restores performance.

Quickshot is a premium fuel additive designed to solve ethanol-related problems in two- and four-stroke gasoline powered small engines and powersports equipment, restoring peak performance. It protects against phase separation – the tendency of ethanol to absorb water and separate from gasoline – by keeping water dispersed throughout the fuel tank. When separated fuel is burned, it creates a leanburn situation that can raise the engine’s running temperature and lead to engine damage. Additionally, separated fuel quickly degrades and forms gum, varnish and other insoluble debris that can restrict fuel flow and hinder engine performance. Water that is not evenly dispersed can also lead to starting, performance and corrosion problems.


Quickshot contains unique chemistry designed to remove and prevent deposits and buildups in fuel systems. It also cleans hard-to-remove deposits on piston tops, spark plugs and other combustion-chamber parts, and it stabilizes fuel between uses and during short-term storage.


Quickshot is recommended for use in all two- and four-stroke gasoline-powered engines, including motorcycles, snowmobiles, boats, personal watercraft, ATVs, edgers, tillers, mowers, snowblowers, chainsaws, generators and farm and construction equipment.

Focused on Quality

Focused on Quality

Quality products are the result of focused effort.

When quality and performance are the main goals, value and customer loyalty are natural side effects.


Dan Peterson, Vice President – Technical Development


AMSOIL is a very fortunate company as we have many loyal customers. I can only guess at all the reasons why people keep coming back to AMSOIL. Maybe it is because they like the outstanding service they get from their AMSOIL Dealers. Or maybe it is due to the range of products or the personal, hometown service they receive from AMSOIL corporate. It could also have something to do with the commitment from AMSOIL to always provide the best value available anywhere. When you buy AMSOIL products, you know you are always going to get the best. I am happy that we provide a combination of reasons for customers to come back again and again. You can call me old-fashioned or naive, but I think people keep coming back because AMSOIL stands apart from this world full of gimmicks, get-rich-quick schemes and here today, gone-tomorrow unbelievable claims. AMSOIL is simply devoted to delivering the best value possible, day in and day out. I would like to have a list of AMSOIL-like companies so I wouldn’t have to search around for who makes the best stuff and who I can count on for the long term.


Since I am the technology guy, I would like to focus on the value that we strive to build into new and reformulated products. Customers buy products based on their perception of the value they will receive from a product and how the product’s benefits compare to the product’s cost. And there are a lot of choices out there, so your proposition has to continually be better than the next guy’s or you won’t stay in business. So how do we go about continually building new value into AMSOIL products? It starts with Al’s commitment to be the best. This does not mean that we have only one motor oil and it is the best in the world; it means that whether it is OE, XL, European Car Formula or Signature Series, we are committed to being the best in that category. When someone chooses an AMSOIL product, that customer can be confident it provides the best value possible.


So what special skills do we have that allow us to continually create the best value in each category? Can’t anyone do this? Well, I didn’t grow up in the big city, but it seems to me that if you are always striving to meet only the minimum requirements while making the most money possible, you get pretty good at making the most money possible on products that barely meet the minimum technical requirements. It is very different at AMSOIL. We are never going to have the cheapest products on the market, and that’s a good thing when you are counting on a thin film of oil to keep your $40,000 new car running for the next 15 years. We start with a different challenge: How do we make products that significantly exceed technical requirements at a price point that customers can afford. If you start with this challenge in mind, you get pretty good at making products that significantly exceed minimum technical requirements at an affordable price.


By always pushing the limits of what can be done technically, we can break barriers and build new value into products that couldn’t be done if we focused solely on cost optimization. One of these new plateaus was recently reached at AMSOIL with the first successful double-length sequence IIIG test. This is an engine test used for API licensing. It runs in a very severe set of conditions, including high oil temperatures and exhaust gas contamination for 100 hours. It tests the ability of the motor oil to resist thickening and keep the engine clean. Our Signature Series 5W-30 product was tested in a planned double-length test (200 hours) to see if it could reach this summit. Not only did it pass, it did so with flying colors. You can expect to see the results from this test in the very near future. We do not know of a commercially available motor oil that has ever reached this mark. Not that they would be striving toward this goal if they are continually getting really good at making more money by meeting the minimum requirements.
