Product Information

1. Higher cetane means better ignition quality.

2. Gen 49D will increase the cetane number of your diesel fuel by 2 to 3 numbers, which is important for efficient engine operation and emission control.
3.Cetane number is a measure of its ignition quality. High cetane number fuels will start to burn earlier in the compression stroke, important for efficient engine operation and emissions.

Cetane Improvers provide

Improved cold start performance
Reduced fuel consumption
Reduced engine noise
Improved engine durability
Decrease in Particulates, Nitrogen Oxides (NOx), Carbon Monoxide, and Hydrocarbon Emissions
Reduce white and black smoke production

General Description:

Gen 49D is an alcohol free lubricant formulated to separate water and provide diesel fuel system performance improvements. Gen 49D is specifically formulated to separate water and provide complete diesel fuel system performance improvements. Gen 49D is specifically formulated to meet all manufacturers requirements including GM, Caterpillar, Cummins and Detroit Diesel.

Primary benefits of using Gen 49D are:

Increased Fuel economy
Improved combustion
Power Increase
Reduced engine wear
Cleaner components
Lower maintenance costs
Reduced emissions
Winter fuel / AntiGel protection
Long term fuel stability
Cold Start Performance



Gen 49D fights water and gelling the leading problem with winter fuel. Cold flow is improved up to 27oF (15oC). This gives your fuel the very best chance of flowing in extreme cold conditions. Gen 49D contains a powerful deicer that lowers the freeze point of water and prevents ice crystals from forming that may plug filters and cause misfiring. Additionally the antigel characteristic keeps crystal molecules from collecting or clumping to ensure problem free winter operation.


Gen 49D adds an excellent stabilizing package to your diesel fuel. High temperature stress on fuels results in degradation products such as particulate solids which may lead to injector damage and filter plugging. Gen 49D also fights the effects of oxygen and water in stored fuel, neutralizing the effect of water.


Diesel fuel is corrosive by nature and corrosion products such as iron oxide cause filter plugging and injector damage. Gen 49D fights corrosion and rust in the fuel tank and through the entire fuel system.


Poor injector spray patterns result in poor combustion and fuel economy while injectors treated with Gen 49D remain clean with a good spray pattern insuring optimal performance.

Fouled Injector Without Gen 49D
Clean Injector With Gen 49D



1.FUEL TANK - Gen 49D begins working in the preflame zone of the fuel system by putting a protective coating inside the fuel tank and lines and stabilizes the fuel which prevents water from causing rust and corrosion.

2.FUEL FILTER - By cutting down on rust and corrosion, fuel filters last longer. Note: Gen 49D may cause fuel filters to become dirty when used for the first time as it will clean the system as it protects. This may require a quick filter change (especially in old or high mileage equipment).

3.FUEL PUMP - The only lubricant in the fuel pump is the fuel itself. Gen 49D adds an environment friendly lubricant to the fuel to prevent excessive wear and premature failure of pumps and injectors.

4.FUEL INJECTOR - Gen 49D is formulated with an injector cleaner that dissolves carbon and other power robbing deposits from the spray nozzle. This generates a better mist improving fuel combustion efficiency and cleaner emissions.

5.CETANE IMPROVER - Increasing the Cetane rating of diesel fuel will cause the fuel to atomize and ignite quicker. This creates a cleaner burn, more power and less smoke. Gen 49D is equipped with Cetane Improvers and combustion enhancers that will increase the Cetane rating of diesel up to 3 numbers.

6.TOP END LUBRICANT - Creating a seal around the top ring is critical in preventing power loss and less blow by of gases into the engine oil. Gen 49D creates this lubricating film on the fire side of the piston giving you a better explosion and more bang for your buck. This results in better fuel economy and improved horsepower.

7.CLEANER EXHAUST - In addition to reducing emissions and engine smoke, Gen 49D will lower exhaust temperatures which shows that the fuel is burning up in the cylinder head, where it is supposed to, and not in the tail pipe.


Starting your equipment each day can seem to be the easiest of all tasks....that is until it won’t start. All the proprietary components of Gen 49D working together ensure exceptional starting efficiency especially in cold conditions. Gen 49D will save unnecessary strain on starters and high stress on batteries. One of the first benefits our customers report is how much easier their equipment fires after applying Power Up Gen 49D for the first time.

Gen 49D contains a powerful synthetic lubricant package which reduces friction and wear in the top end of the cylinder, injectors and fuel pump. Poor fuel lubricity is commonly seen in new low sulphur fuels. Gen 49D is approved for and surpasses the new standards for diesel fuel and exhibits wear and friction reduction significantly below typical levels. Poor fuel lubricity results increased maintenance costs, downtime and poor fuel economy. In the HFRR test, we see typical fuel measure in excess of 500 microns of wear, the 2005 standard will be 460 micron of wear.

Gen 49D protects your fuel pump, the injectors and top end of the engine from premature wear and failure, reducing costs and increases life over straight diesel fuel.

The preflame region before fuel enters the combustion chamber is only a small part of the complete lubrication protection offered by Gen 49D. Gen 49D is designed and formulated to lubricate the top end of the combustion chamber where the severe stresses of burning new, dry low sulphur fuels are causing premature wear and poor performance. Fuel injectors, intake and exhaust valves and piston rings are being subjected to more extreme conditions than ever before.
