Diesel Concentrate Performance Fuel Additive (ADF) Total system cleaner and lubricity improver for all types of diesel engines. Excellent for ultra low sulfur diesel and biodiesel fuel. See Pricing Information or Place an Order Package sizes include: 16-oz. Bottle 16-oz. Bottles (case of 12) 5-Gallon Pail 55-Gallon Drum | | Product Description AMSOIL Diesel Concentrate (ADF) provides maximum diesel operating efficiency. It compensates for the variances in quality of different fuels (including biodiesel) and the deficiencies of today’s Ultra Low Sulfur Diesel fuel (ULSD) for better engine operation. New engine technology, tighter tolerances and emission regulations require high-quality diesel fuel for long-term engine operability. AMSOIL Diesel Concentrate meets the low sulfur mandate. It improves diesel fuel quality to exceed today’s stringent performance requirements. AMSOIL Diesel Concentrate extends equipment life, lowers operating costs and improves diesel performance. Improves Fuel Economy and Restores Horsepower As diesel engines are used, they become less efficient over time. Fuel injector deposits interrupt spray patterns, causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. Tests prove that AMSOIL Diesel Concentrate cleans dirty injectors, improving fuel economy by up to five percent and restoring horsepower to like new. Acceleration is improved and with regular use, AMSOIL Diesel Concentrate continues to enhance performance by keeping injectors clean. The net savings on fuel expense can result in no additional cost to vehicle operation. | Lubricates Fuel Pump and Injectors Ultra low sulfur diesel fuel has significantly reduced lubricity – a critical property in controlling wear in fuel pumps and injectors. AMSOIL Diesel Concentrate adds back all the lubricity properties needed and more. Fuel pump and injector service life is extended, saving time and money on maintenance costs. Reduces Cylinder Wear, Retains Engine Oil TBN Longer With high rates of exhaust gas recirculation (EGR) in modern diesel engines, acids from combustion are of particular concern. AMSOIL Diesel Concentrate neutralizes acids during combustion. It helps reduce acid caused cylinder wear and helps extend engine oil TBN, maintaining engine oil quality longer for better protection. Minimizes Soot Loading AMSOIL Diesel Concentrate is a powerful cleaner that cleans fuel injectors and piston rings for improved combustion and better sealing. It minimizes soot generated from incomplete combustion and helps keep soot out of the crankcase. Reduced soot loading controls soot related wear and engine oil viscosity increase. Fuel Stabilizer Fuel degradation can cause gums, which increase deposits and the chance of filter plugging. AMSOIL Diesel Concentrate significantly improves the oxidation and thermal stability of diesel fuel. It overcompensates for ultra low sulfur diesel fuel’s potential stability loss caused by extra processing and sulfur removal. Diesel fuel treated with AMSOIL Diesel Concentrate easily meets the requirements of the National Council of Weights and Measures (NCWM) Premium Diesel Fuel Specification for resisting diesel fuel degradation. Improves Water Tolerance AMSOIL Diesel Concentrate is an alcohol-free product that protects fuel systems against water contamination. It helps prevent fuel/water emulsions and it protects metal against rust. Water can be drained easier and fuel filters are less likely to plug, ensuring drivability. Heating Oil Improver AMSOIL Diesel Concentrate provides many of the same benefits in heating oil furnace applications. It provides fuel oil storage stability, water stability, rust protection, fuel oil filter longevity, and its exceptional cleaning properties are expected to keep fuel oil nozzles clean for proper spray in the combustion chamber. AMSOIL Diesel Concentrate promotes trouble-free operation. AMSOIL Cold Flow Improver is recommended where fuel oil is stored outside. Recommendations AMSOIL Diesel Concentrate is recommended for use with all types of heavy- and light-duty, on- or off-road and marine diesel engines. Recommended mix ratio is one oz. of additive per five gallons of fuel. Use with every new tank of fuel for the best performance and protection against fuel pump wear, injector wear and injector deposits. Compatible with all types of exhaust emission systems such as diesel particulate filters (DPFs). Add Diesel Concentrate to fuel before storage. Excellent for use with AMSOIL Cetane Boost and AMSOIL Cold Flow Improver. This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines.

Diesel Cold Flow Improver (DFF) A premium fuel additive that lowers diesel fuel cold flow properties as much as 20°F (11°C).See Pricing Information or Place an Order Package sizes include: 16-oz. Bottle 16-oz. Bottles (case of 6) 5-Gallon Pail 55-Gallon Drum PRODUCT DESCRIPTION AMSOIL Cold Flow Improver for diesel fuel is designed for use in Ultra Low Sulfur Diesel fuel (ULSD) and conventional fuels. It functions by modifying wax crystal formation at low temperatures to depress the pour point and improve cold flow filtration properties. AMSOIL Cold Flow Improver contains jet fuel-type deicer to help prevent ice formation in fuels contaminated with water. It is recommended for use with all diesel engines and is compatible with diesel exhaust particulate filters (DPFs). AMSOIL Cold Flow Improver is recommended for use in #2 diesel fuel, #1 diesel fuel, kerosene, heating oil and biodiesel. Add AMSOIL Cold Flow Improver to diesel fuel above the fuel cloud point, which is the temperature wax crystals begin to form. Diesel fuel cloud point varies greatly with some lesser-quality diesel fuels forming wax as warm as 40° F (4°C). AMSOIL recommends treating diesel fuel at a minimum of 32°F (0°C), insuring the fuel is properly treated inmost every case. AMSOIL Cold Flow Improver is designed to control wax crystal formation. It does not reverse wax or gel once formed. Note – Do not store below 0°F (-18°C) as product will solidify in its concentrated state when not mixed with fuel. However, once combined with diesel fuel, it effectively lowers diesel fuel cold filter plugging performance as much as 20°F (11°C).

What does “octane number” mean? Why does it matter? The tendency of a hydrocarbon fuel, such as gasoline, to knock is measured by its octane number. Lower numbers denote a greater knock tendency; higher numbers denote greater knock control. “Knock” is an uncontrolled and explosive ignition of fuel in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. Knock may be eliminated with the appropriate octane number. |

P.I. Performance Improver Concentrate (API) AMSOIL PI improved fuel economy by reducing port fuel injector deposits, intake valve deposits and combustion chamber deposits in 100% of the vehicles tested! Reformulated for greater potency See Pricing Information or Place an Order Package sizes include: 12-oz. Bottle 12-oz. Bottles (case of 12) Also available in single-use bottles of P.I. Quickshot | | Untreated Fuel Leads to Poor Engine Performance A vehicle demonstrates its best efficiency and engine performance when it is new. As the engine ages, its performance suffers from gasoline fuel-generated deposits that form on the fuel injectors, intake valves and combustion chamber. Additives are required to control deposit formation. Today’s fuels, however, lack sufficient treatments of either enough additives or high quality additives. Fuel system deposits result in the following: • Lost fuel economy • Lost power and poor throttle response • Failed emission tests • Poor drivability - surging, hesitation, stalling, rough idle • Engine knocking (pinging) and rap • Difficult starts Treated Fuel Delivers Maximum Performance AMSOIL PI is the most potent gasoline additive available today. As a concentrated detergent, it is unsurpassed in cleaning combustion chamber deposits, intake valve deposits and port fuel injector deposits. AMSOIL PI helps maintain peak engine efficiency, fuel economy, power and drivability in newer low mileage engines. In engines with accumulated deposits, testing showed AMSOIL PI provided the following clean-up benefits after only one tank of gasoline: • Improves fuel mileage an average of 2.3% and up to 5.7% • Reduced emissions • hydrocarbons (HC) up to 15% • carbon monoxide (CO) up to 26% • nitrous oxides (NOx) up to 17% • Restored power and performance • Reduced need for costly higher octane fuel • Reduced noise from carbon rap and pre-ignition • Better drivability • Smoother operation AMSOIL PI works as an “emissions passer.” It is ideal for use prior to emissions inspections. Unsurpassed Deposit Clean-up Port Fuel Injector Deposits form after the engine has been shut down and there is no gasoline flowing through the injectors. During this “hot soak” period the injectors heat up and the gasoline remaining in the injectors degrades and forms deposits. This can happen very quickly with the use of poor quality gasoline and short trip driving. Because the clearances within the injectors are extremely tight and injectors must deliver precise amounts of “atomized” fuel, even small amounts of deposits can cause injectors to malfunction. Fuel flow is reduced and spray patterns are disrupted, decreasing engine efficiency, power and fuel economy, while increasing exhaust emissions. Intake Valve Deposits form on the intake side or back side of the valves. As deposits increase, they restrict airflow and alter airflow patterns in the cylinder. The deposits disrupt the balanced air/fuel ratio by momentarily absorbing and releasing fuel, and they can cause valve sticking by getting in the way of the valve stem and guide. Deposits also restrict proper seating, and the valves may be burned. Intake valve deposits cause lost engine power, increased emissions, poor engine efficiency and potential valve failure. Combustion Chamber Deposits form on the top of the pistons and on the cylinder heads. They increase compression and absorb heat during combustion to later release it during the intake cycle. In some engines with tight squish domes, combustion chamber deposits cause the piston to actually hit the cylinder head. This is referred to as combustion chamber deposit interference or “carbon rap.” Combustion chamber deposits also flake off as they get large, and these flakes can get trapped between the valves and valve seat, resulting in compression loss, difficult starting and rough idle. Higher compression and stored heat cause increased intake fresh charge temperatures and the increased likelihood of pre-ignition “knock” or “pinging” when the fuel spontaneously combusts prior to spark ignition. This increases emissions and may cause engine damage. Many of today’s cars have “knock” sensors that adjust spark timing to prevent knock. Although audible knock is controlled, power is lost from retarded timing. Higher octane fuels of 4-5 octane numbers can be used to help prevent knock, an effect called “octane requirement increase.” As a vehicle ages, more expensive higher octane fuel is needed to keep it operating at peak performance. By cleaning combustion chamber deposits, knock is controlled, power is restored, fuel economy increases and higher octane fuels are less necessary for peak performance. Maximum Fuel Economy AMSOIL PI maximizes fuel efficiency by dissolving and removing fuel system deposits and other contaminants for improved power and overall performance. Recommendations Treat one full tank of gas every 4,000 miles or 100 hours of service. One bottle treats 20 gallons of gas. Do not treat and run more than 40 gallons of gas per treatment. PI helps pass emissions tests. Treat gas, run that tank and fill up again prior to test. Safe for use with catalytic converters, oxygen sensors, oxygenated gas and 10% ethanol blended gas. DANGER: Combustible. Harmful or fatal if swallowed. Harmful if inhaled. Skin and eye irritant. Read precautions on container before use. |
