Best Diesel Additive To Clean Injectors: 10 Options Compared

#1 · Best Overall

1. Archoil Diesel Fuel System Kit

• Size: 1 Count (Pack of 2)

Best for: Two-stage fuel-system care.

Why it ranks #1: Pairs a dedicated AR6400-D cleaner with AR6500 treatment; the cleaner treats 30–40 gallons and the follow-up bottle treats up to 400.

A dedicated cleaner followed by a maintenance treatment sets the Archoil Diesel Fuel System Kit apart, giving owners a defined sequence for cleaning and continued fuel-system care. AR6400-D treats 30–40 gallons, then AR6500 is used at fill-ups, with the kit listed for all diesel engines.

The two-step workflow separates an initial cleaning dose from ongoing treatment: AR6400-D is the first step and its 12-ounce amount treats 30–40 gallons, while AR6500 follows at every fill-up and its 40-ounce supply treats up to 400 gallons. That structure helps owners distinguish reset treatment from routine use. Archoil lists compatibility with pre-emissions diesel vehicles and modern high-pressure common-rail engines, broadening the stated fit across older and newer systems.

Skip it if you want one product to add at every fill-up; Lucas Oil 10003 is listed as a fuel-system cleaner and lubricant.

This kit suits diesel owners who want a stated clean-then-maintain sequence, including users of modern HPCR or pre-emissions engines. Account for the two-step workflow: AR6400-D comes first, with AR6500 reserved for continued treatment.

#2 · Best Single-Bottle Cleaner

2. Power Service Diesel Kleen 64 oz

• Weight: 4 lb

Best for: Injector deposits and wear protection.

Why it ranks #2: Specifically removes internal and external injector deposits and prevents sticking in HPCR and older systems; the 64-ounce bottle is a substantial single product.

Power Service Diesel Kleen+Cetane Boost specifically targets both internal and external injector deposits, giving owners a clearly stated cleaning focus. Its formulation also includes Slickdiesel Lubricator, linking injector care with protection for fuel pumps and injectors across HPCR and older diesel systems.

The stated ability to remove internal and external injector deposits addresses more than surface buildup, while preventing injector sticking in both HPCR and older systems. That broad system compatibility makes it relevant to owners who do not want to limit their choice to one injection design. Slickdiesel Lubricator is included to protect fuel pumps and injectors from increased wear associated with poor-quality ULSD. The listing also names ULSD, biodiesel, and biodiesel blends as compatible fuels.

Skip it if you need a defined two-step clean-and-maintain schedule; Archoil Diesel Fuel System Kit lists separate cleaner and treatment stages.

Choose this 64-ounce Power Service treatment if injector deposits, sticking, and fuel-system wear are the concerns, especially across varied diesel fuels. Its listed compatibility spans HPCR and older systems, but the bottle size may not suit a small-dose preference.

#3 · Best Whole-System Clean

3. Hot Shot's Secret Diesel Extreme

• Weight: 0.45 kg
• Size: 16 Fl Oz (Pack of 1)

Best for: Whole-system diesel cleaning.

Why it ranks #3: Its listed purpose is a complete fuel-system clean, addressing deposits, water, and sludge while also improving cetane.

Hot Shot’s Secret Diesel Extreme is described as working through the entire fuel system, removing deposits, water, and sludge in a single 16-ounce liquid treatment. Its stated performance aims include improved cetane, easier starts, and stronger acceleration, making it a more comprehensive cleaning option.

The listed action against deposits, water, and sludge gives Diesel Extreme a broader fuel-system cleaning remit than an injector-only description. The product also says it improves cetane for smoother, more efficient combustion, connecting fuel treatment with the engine’s operating process. Easier starts and stronger acceleration are named performance benefits, while the 16-ounce bottle provides a compact format for owners handling a single treatment. The listing identifies the formula as containing cumene and fragrance free.

Skip it if you want repeated fill-up dosing from a stated 40-ounce supply; Archoil AR6500 treats up to 400 gallons per bottle.

Diesel Extreme suits owners seeking a compact treatment with stated whole-system cleaning that includes water and sludge, as well as cetane improvement. The listed container is 16 ounces, so consider that format when planning treatment quantity.

#4 · Best Multipack

4. Power Service Diesel Kleen 12 oz

• Weight: 8 lb

Best for: Multi-dose injector treatment supply.

Why it ranks #4: Targets dirty and sticking injectors in HPCR and older systems, and its nine 12-ounce bottles suit buyers who want multiple applications on hand.

Nine 12-ounce units give this Power Service Diesel Kleen listing a multi-dose supply, while its stated injector cleaning covers HPCR and older systems. It removes internal and external deposits, helps prevent sticking, and includes Slickdiesel Lubricator for fuel-pump and injector protection.

The pack combines nine 12-ounce bottles with a treatment whose listed actions include removing internal and external injector deposits and preventing sticking. That makes the supply relevant to owners planning repeated diesel treatment rather than buying a single bottle. Compatibility extends to HPCR and older systems, and the listing names ULSD, biodiesel, and biodiesel blends. Slickdiesel Lubricator is included to help protect fuel pumps and injectors from increased wear associated with poor-quality ULSD.

Skip it if you need one larger bottle rather than multiple small ones; Power Service Diesel Kleen+Cetane Boost 64 oz is listed as a single bottle.

This pack fits diesel owners planning ongoing injector treatment and wanting listed coverage for several diesel-fuel types. Its nine-bottle format is a substantial supply, so it is less suitable when you only need a single treatment.

Listed on Amazon as: Power Service Diesel Kleen +Cetane Boost – 12 Ounce (Pack of 9)

#5

5. Lucas Oil Diesel Deep Clean

• Weight: 249 g
• Size: 1 Count (Pack of 1)

Best for: Lucas Diesel Deep Clean bottle.

Why it ranks #5: The product is explicitly labeled Diesel Deep Clean, making it relevant to injector-cleaning shoppers, though the supplied details provide little dosing or cleaning information.

Lucas Oil’s Diesel Deep Clean is explicitly identified as a diesel-specific product, offering a focused alternative to the brand’s broader gasoline-and-diesel fuel treatment. This listing specifies a 16-ounce bottle, but gives few product-performance details beyond the Diesel Deep Clean name.

The title identifies this product as Diesel Deep Clean, so its stated category is more targeted than a general fuel treatment covering both gasoline and diesel. The supplied specifications describe a 16-ounce bottle and identify Lucas Oil as the brand, giving buyers a clear product format to consider. However, the provided feature information does not explain a dosing rate, treatment coverage, or particular injector-cleaning mechanism. That limited detail makes it harder to plan use from the listing alone.

Skip it if you require a stated injector-deposit mechanism and fuel compatibility; Power Service Diesel Kleen+Cetane Boost lists both.

This may suit Lucas Oil shoppers seeking a product titled Diesel Deep Clean in a 16-ounce bottle. The supplied listing gives limited usage and performance detail, so buyers needing a stated dose or injector-cleaning action should choose a more fully specified option.

Listed on Amazon as: Lucas Oil 16 Oz. Diesel Deep Clean – 1 Each

#6

6. Lucas Oil Fuel Treatment

• Weight: 898 g
• Size: 32 Fluid oz

Best for: Multi-engine fuel-system treatment.

Why it ranks #6: The listed claims include cleaning and lubricating fuel injectors, but this quart-size treatment also targets gasoline engines and broader fuel-system needs.

Lucas Oil 10003 covers both gasoline and diesel fuel systems, making it a flexible option for owners maintaining more than one engine type. For diesel use, the listed functions include cleaning and lubricating fuel injectors, alongside claims about fuel flow, deposits, power, and acceleration.

The 32-ounce bottle is listed for gasoline and diesel fuel, so owners with mixed engine types can use one fuel-treatment product across both categories. Lucas says it cleans and lubricates fuel injectors, carburetors, and combustion chambers; that wider component scope may suit buyers looking beyond injector cleaning alone. The listing also connects reduced deposit buildup and improved fuel flow with power and acceleration. It additionally describes burning excess exhaust emissions as a fuel-economy benefit.

Skip it if you want a diesel-only treatment with stated HPCR injector coverage; Power Service Diesel Kleen+Cetane Boost lists both HPCR and older systems.

This suits owners seeking one fuel treatment for gasoline and diesel engines, with injector cleaning among several listed functions. Diesel-only buyers focused on a narrowly specified injector cleaner may prefer a product whose details concentrate on diesel systems.

Listed on Amazon as: Lucas Oil 10003 Fuel Treatment – 1 Quart

#7

7. Power Service Diesel Kleen 64 oz 6-Pack

• Size: 64 oz

Best for: Bulk cetane-boost treatment.

Why it ranks #7: Cleans dirty injectors and prevents sticking in HPCR and older systems; the six-bottle format is most relevant to frequent or fleet use.

Six 64-ounce bottles make this Power Service Diesel Kleen listing a substantial supply, with a stated cetane boost of up to six numbers. It also targets dirty injectors and sticking across HPCR and older systems, while listing compatibility with ULSD, biodiesel, and blends.

The six-bottle format suits owners who want multiple 64-ounce containers on hand, rather than a single treatment bottle. Power Service lists cleaning for dirty injectors and prevention of injector sticking in both HPCR and older systems, giving the product a defined focus across injection types. The stated cetane boost of up to six numbers is linked to smoother running, less power lag, and faster cold starts. Compatibility includes all diesel vehicles and several diesel fuel types.

Skip it if you need a single bottle for a limited treatment; Power Service Diesel Kleen+Cetane Boost 64 oz is listed as one bottle.

This bulk pack fits diesel owners seeking repeated injector cleaning and cetane treatment, with listed coverage for older and HPCR systems. Its six 64-ounce bottles make it a poor match for buyers wanting only one treatment.

#8

8. Archoil AR6500 Diesel Treatment

• Weight: 2.94 lb

Best for: At-fill-up diesel treatment.

Why it ranks #8: Includes injector cleaning among ongoing treatment functions and one 40-ounce bottle treats up to 400 gallons, but it is designed for fill-up use.

A long neck and measuring chamber make Archoil AR6500’s at-fill-up routine easier to manage, while its 40-ounce bottle treats up to 400 gallons. It combines injector cleaning with lubricity improvement and deposit control, and is listed for diesel vehicles and equipment including modern HPCR systems.

Adding the treatment directly to the tank at each fill-up creates a repeatable maintenance routine, and the measuring chamber helps portion the liquid without relying on a separate measuring tool. Archoil says one 40-ounce bottle treats up to 400 gallons, which gives owners a stated coverage figure for planning continued use. Its listed 43% lubricity improvement is tied to helping protect fuel-system components, while injector cleaning and DPF and turbo deposit control extend its stated focus beyond injectors.

Skip it if you want an initial deep-clean stage before maintenance dosing; Archoil Diesel Fuel System Kit includes AR6400-D for that first step.

AR6500 fits owners who prefer a measured treatment at each fill-up and want stated lubricity and deposit-control benefits alongside injector cleaning. It is listed for a wide range of diesel vehicles and equipment, but its routine is ongoing rather than a separate reset stage.

#9

9. Archoil AR6500 Diesel Treatment 2-Pack

• Weight: 6.29 lb

Best for: Extended AR6500 maintenance supply.

Why it ranks #9: Two 40-ounce bottles treat 800 gallons total and include injector-cleaner claims, but the product is an ongoing treatment rather than a dedicated deep cleaner.

Two 40-ounce bottles provide Archoil AR6500 treatment for up to 800 gallons total, giving repeat users a clearly stated extended supply. The formula is listed for every-fill-up use and covers injector cleaning, lubricity improvement, and DPF and turbo deposit control across diesel vehicles and equipment.

Each bottle treats up to 400 gallons, so the two-pack’s 800-gallon total helps owners plan continuing treatment without relying on a single bottle. Archoil directs users to add it directly to the fuel tank at each fill-up, keeping the maintenance workflow consistent. Listed compatibility includes light-duty and heavy-duty vehicles, pickups, SUVs, vans, RVs, and modern HPCR systems. The stated 43% lubricity improvement relates to protection for fuel-system components, including wear-sensitive parts.

Skip it if you want a cleaner as a first step before ongoing treatment; Archoil Diesel Fuel System Kit includes AR6400-D for that stage.

This two-pack suits diesel owners committed to repeated fill-up treatment, especially those seeking stated compatibility across vehicle types and HPCR systems. Its 800-gallon total is best matched to ongoing use rather than a one-time injector-cleaning need.

#10

10. Hot Shot's Secret Everyday Diesel Treatment

• Weight: 16 oz
• Size: 16 Fl Oz Squeeze

Best for: Routine diesel maintenance.

Why it ranks #10: This routine treatment focuses on engine performance and cetane improvement up to seven points; the supplied details do not specifically establish injector cleaning.

Cetane improvement of up to seven points is the clearest reason to consider Hot Shot’s Secret Everyday Diesel Treatment: it gives diesel owners a routine additive focused on fuel economy and engine upkeep. Its 16-ounce liquid bottle suits buyers seeking an everyday treatment, rather than a two-step cleaning kit.

The listing positions EDT for regular use to maintain engine health and improve performance, making it a fit for owners who want an ongoing addition to their diesel routine. Its stated cetane boost of up to seven points is tied to better fuel economy, while the squeeze-bottle format offers a straightforward way to handle a 16-ounce liquid treatment. The listed benefits emphasize routine upkeep and fuel performance, not a specified injector-cleaning process or deep-clean treatment.

Skip it if you need a specifically described injector cleaner; Power Service Diesel Kleen+Cetane Boost lists injector deposit removal.

For diesel owners seeking a routine liquid treatment with a stated cetane boost and fuel-economy focus, EDT is a reasonable fit. Its listing does not detail injector cleaning, so choose another option if that is the priority.
