AMSOIL Diesel Recovery Fuel Treatment
AMSOIL Diesel Recovery (DRC) is an emergency diesel fuel treatment that dissolves the wax crystals that form when diesel fuel passes its cloud point. The formula liquefies gelled diesel fuel, thaws frozen fuel filters, and restores fuel flow so a stalled or no-start diesel can be returned to service. Diesel Recovery is the recovery additive for trucks, tractors, and off-road equipment that have already gelled up in cold weather, not a preventive winterizer added before temperatures drop.
Fast thaw for gelled diesel fuel
When ambient temperatures fall below the cloud point of the diesel in the tank, paraffin wax dissolved in the fuel begins to crystallize. As more wax precipitates out, the crystals stick together, plug the fuel filter, and starve the injection pump. The result is a hard start, a stalled engine, or a no-start truck waiting on a tow.
Diesel Recovery breaks the molecular bonds holding agglomerated wax crystals together so the gelled fuel returns to a liquid state. Restoring flow through the filter and injection system means the operator can continue driving with minimal downtime instead of paying for a tow back to a service station.
Thaws frozen fuel filters and reduces filter replacement
Cold-soak conditions often freeze the wax cake directly inside the fuel filter media, where it stops fuel from reaching the engine even after the tank itself has been treated. Diesel Recovery is designed to dissolve that wax buildup inside the filter, which means a frozen filter can often be returned to service rather than replaced on the side of the road. For the fastest power restoration, installing a new fuel filter while treating the system speeds up recovery time.
Compatible with ULSD, off-road diesel, and biodiesel
Pump diesel quality varies from one filling station to the next, and winter blends, summer fill, and biodiesel mixes all behave differently as temperatures drop. Diesel Recovery performs well across the common diesel pool, including ultra-low-sulfur diesel (ULSD), red-dye off-road diesel, and biodiesel blends. That broad compatibility makes the bottle a single-solution emergency treatment for fleets running mixed equipment on whatever fuel is available in the tank.
Alcohol-free and non-corrosive formulation
Many emergency fuel additives rely on alcohol to dissolve ice and wax, but extended alcohol exposure can degrade rubber seals, hoses, and other components in modern fuel delivery systems. Diesel Recovery contains no alcohol and is non-corrosive, which makes the formula safe for repeated treatments across the winter without risking seal damage, premature filter clogging, or attack on injection-pump internals.
Safety in a bottle for cold-weather operators
Low-quality diesel fuel can have a cloud point as high as 40 F, which means gelling can begin well before deep winter cold sets in. Carrying a bottle of Diesel Recovery in the truck, tractor, or service rig is inexpensive insurance against being towed to a service station or stranded in subzero temperatures. The 30 oz. bottle treats up to 30 gallons of fuel, enough to recover a full pickup tank or knock down a partial gel in a larger heavy-duty tank.
Recommended applications and service procedure
Diesel Recovery is designed for emergency thaw service on diesel fuel that has already gelled or frozen the filter. For preventive winter protection added before temperatures drop, AMSOIL Diesel Cold Flow (ADD) and AMSOIL Diesel All-In-One (ADB) are the right products. To restore a gelled fuel system with Diesel Recovery, follow the on-bottle procedure:
- Remove the existing fuel filter from the engine.
- Fill the empty fuel filter with Diesel Recovery, then reinstall it on the engine.
- Add the remaining Diesel Recovery to the fuel tank, treating at up to 30 gallons of fuel per 30 oz. bottle. If the system is heavily gelled, add another bottle as required by the treat-rate guidance on the label.
- Start the engine and allow the fuel system to circulate Diesel Recovery until full power has been restored. For the fastest recovery, install a new fuel filter in place of the gelled filter when conditions allow.
Diesel Recovery is for emergency thaw use only and is not a substitute for a preventive cold-flow improver. For ongoing winter protection, pair Diesel Recovery in the cab with a preventive treatment like Diesel Cold Flow added to the tank before the first hard freeze. To match the right preventive additive, fuel filter, and engine oil to a specific truck or piece of equipment, see the AMSOIL vehicle lookup guide and the AMSOIL diesel oil guide.
Order AMSOIL Diesel Recovery Fuel Treatment
Diesel Recovery is sold in a 30 oz. bottle as product code DRCQT-EA, with case-of-12 packaging available as DRCQT-CA for fleet, farm, and shop stocking. AMSOIL products are backed by the AMSOIL Limited Liability Warranty. Match the right preventive fuel additive, diesel oil, and filter for the truck or equipment with the AMSOIL vehicle lookup guide, then compare diesel oil families in the AMSOIL diesel oil guide, and order AMSOIL Diesel Recovery Fuel Treatment.

Don’t Leave Home Without This
I live in the extreme Backwoods of the Black Hills in Wyoming, it gets-40 and diesel will get gelled, this product will get the fuel moving.

great in a jam
have not had to use it yet this bottle is just replacing the bottle I used last winter. which that one worked well.

Perfect product
Before using the all in one. I had my fuel gel up on me in sub zero weather and this got the truck back going in no time flat.

Frequently asked questions
When does diesel fuel start gelling?
Gelling begins when fuel temperature drops below the cloud point of the specific diesel in the tank. Cloud point varies by fuel quality, blend, and time of year, and low-quality pump diesel can have a cloud point as high as 40 F. Once temperature falls below cloud point, paraffin wax crystallizes out of the fuel, accumulates in the filter media, and eventually stops fuel flow to the engine.
How is Diesel Recovery different from Diesel Cold Flow or Diesel All-In-One?
Diesel Recovery is an emergency thaw additive used after a fuel system has already gelled or after a fuel filter has frozen. Diesel Cold Flow (ADD) and Diesel All-In-One (ADB) are preventive cold-flow products added before temperatures drop. Diesel Recovery dissolves wax that is already there; the preventive additives are designed to keep that wax from forming a solid plug in the first place.
How much Diesel Recovery is needed to thaw a gelled fuel system?
One 30 oz. bottle of Diesel Recovery treats up to 30 gallons of diesel fuel. For a heavily gelled system or a larger heavy-duty tank, add another bottle as required by the treat-rate guidance on the label. Filling the existing fuel filter with Diesel Recovery before reinstalling it is part of the recommended procedure, and that volume is included in the bottle dosage.
Will gelled diesel fuel thaw on its own if the truck warms up?
Wax crystals that have already formed will redissolve as fuel temperature rises back above the cloud point, but waiting on ambient temperatures or cab heat alone is unreliable in deep cold. Diesel Recovery actively breaks the molecular bonds between agglomerated wax crystals and clears wax inside the fuel filter that is otherwise insulated from cab heat, restoring flow much faster than passive warming.
Is Diesel Recovery safe for ULSD, off-road, and biodiesel?
Yes. The formula is designed to perform well in ultra-low-sulfur diesel, red-dye off-road diesel, and common biodiesel blends. Diesel Recovery contains no alcohol and is non-corrosive, so it does not attack rubber seals, hoses, or fuel-system metals during repeated cold-weather treatments.
Does Diesel Recovery damage the fuel filter or injection pump?
No. Diesel Recovery is non-corrosive and contains no chemicals that interact aggressively with fuel system components. The product is intended to be installed inside the fuel filter and circulated through the injection system as part of the recovery procedure, with no impact on filter media life or injection-pump hardware beyond the gelled wax it is designed to dissolve.
Should the fuel filter be replaced after a gelling event?
Diesel Recovery is engineered to thaw a frozen filter and return it to service, which avoids an unplanned trip to an auto parts store. For the fastest restoration of full engine power, installing a new fuel filter in place of the gelled one is recommended whenever conditions allow. If a new filter is not on hand, the existing filter can be filled with Diesel Recovery and reinstalled to recover the system, then changed at the next normal service interval.
