RV PREMIUM DIESEL ADDITIVE is a multi-functional diesel fuel additive that greatly upgrades power, performance, fuel economy and fuel stabilization for all diesel RVs.

RV PREMIUM DIESEL ADDITIVE boosts diesel’s cetane rating, creating more power and better fuel economy. It also provides excellent fuel lubrication to promote greater reliability and longevity.

RV PREMIUM DIESEL ADDITIVE prevents gum and varnish from forming inside the fuel system, including fuel injectors, while also improving fuel stability allowing for long term storage.

Recreational vehicles are designed and built with a specific purpose in mind. The additives you use in your RV should be the same way. That is why Hot Shot’s Secret engineered the first line of products specifically for RVs. Hot Shot’s Secret’s RV line of products are fully formulated, high quality products created to solve specific RV related problems, improve performance, fuel economy and reliability. When hitting the open road, you should not have to worry about your RV’s performance and whether you’ll hit mechanical “roadblocks” while traveling. Be confident your RV will perform as promised when using Hot Shot’s Secret RV products.

Should be used at every fill-up. 2 OZ per 25 GALLONS

USE IN ALL DIESEL ENGINES (including tier 4 compliant) & diesel generators.


Changes to the industry have brought about a unique set of problems for diesel owners. Ultra-Low Sulfur Diesel (ULSD) along with High Pressure Common Rail Injectors are the main culprits. Sulfur was a very good lubricant. The removal of sulfur causes all the moving parts in your fuel system to suffer. Waxy soap deposits that were soluble in higher sulfur content fuels are now being formed and are difficult to filter.
 Fuel Systems incorporating High Pressure Common Rail Injectors operate at higher pressures which create high heat. This heat chemically changes the hydrocarbons in the fuel to longer chain hydrocarbons called asphaltenes, which can block fuel filters. The tolerances for the Common Rail injectors are very tight, sometimes around 1-3 microns. Even small deposits can cause an injector to stick.
Several sources of sodium and calcium contamination occur from residual refinery salts, storage tanks, ship ballasts and biodiesel catalysts, to name a few. Dodecenyl succinic acid (DDS) and hexadecenyl succinic acid (HDS) are commonly found in certain pipeline corrosion inhibitors, refineries and aftermarket additive packages. When the contamination from the sodium or calcium reacts with the DDS or HDS, carboxylic salts are formed. These carboxylic salts have very low solubility in ULSD and are very difficult to filter. The smaller molecules end up depositing on the internals of your fuel injectors causing what are known as Internal Diesel Injector Deposits (IDIDs).
Hot Shot’s Secret RV Premium Diesel was formulated to take care of the headaches of these complex systems. RV Premium Diesel is fully formulated with an injector cleaner, cetane improver, sulfur free lubricity agent, water demulsifier, rust and corrosion inhibitor and fuel stabilizer. RV Premium Diesel’s injector cleaner specifically cleans IDID’s as well as the original carbon coking External Diesel Injector Deposits (EDID’s) and waxy soap deposits. RV Premium Diesel’s injector cleaner will clean all parts of your fuel system, including upper cylinders, fuel tank, fuel pumps and lines. The injector cleaner is also responsible for bringing asphaltenes and glycerides back into solution and preventing further asphaltenes and glycerides from forming.
With your diesel fuel void of carboxylic salts, waxy deposits, asphaltenes and glycerides in suspension, the problems with filter plugging and injector deposits are solved. DDS and HDS acids are neutralized by the injector cleaner to keep more carboxylic salts from forming. Independent testing has shown that power loss is restored up to 67% in the Peugeot CEC F98-08 DW-10 test with the keep clean level of injector cleaner found in RV Premium Diesel. It also passes the ASTM D2068 Filter Blocking Test.
The Cetane levels found in diesel fuel in most states are around 42 to 45. The minimum required by ASTM D 975 is 40. Most diesel engines operate more efficiently with fuel that has a cetane rating of 48 to 50. Fuels with higher cetane burn more efficiently and completely than those with lower cetane ratings.  RV Premium Diesel contains a cetane improver that will raise your cetane number 6 points. There are many advantages to having increased cetane numbers in your fuel, including improved cold starting and less black smoke due to the improved combustion efficiency. Less hydrocarbons and particulate matter in your exhaust reduce the blocking of your Diesel Particulate Filter and using RV Premium Diesel in your fuel has been shown to reduce DPF regens 50%, saving you time and money. Increased cetane levels have also shown to improve fuel mileage, throttle response and power 
RV Premium Diesel contains Hot Shot’s Secret LX4 Lubricity Extreme lubricity additive for fuel pump and injectors that has a proven wear scar reduction of below the Engine Manufacturers Associations recommended 460µm in ASTM D6079 test. A Military grade non-alcohol-based water demulsifier lowers the freeze point of water in fuel over 32°F over competitor’s water dispersants. With the condensed water in the fuel removed, the major cause of rust, icing in cold weather and the growth of microorganisms in warm weather is inhibited.  RV Premium Diesel contains a package that inhibits rust and corrosion in tank and lines and has a NACE corrosion test rating of A. To round out the package, a specialty fuel stabilizer was chosen that contains anti-oxidants, metal deactivators and dispersants for times when your RV is not on the road.



No other diesel oil or fuel additive has a better guarantee than Hot Shot’s Secret products. If our products do not deliver as promised, then we will give you your money back. End of story.
