Best Diesel Fuel Cleaner for Injectors, Tanks, and Routine Use

#1 · Best Overall

1. Chevron Techron D Concentrate

• Volume: 20 fluid oz
• Size: 20 Fl Oz (Pack of 1)

Best for: One-tank injector deposit cleanup.

Why it ranks #1: Its concentrated formula is described for a one-tank fuel-system cleanup, treats up to 35 gallons, and lists a 3,000-mile treatment cycle.

Chevron Techron D is described as a concentrated, one-tank cleanup treatment that reaches deposits across the fuel system, including internal injector deposits. A treatment can cover up to 35 gallons, and the listing recommends a 3,000-mile cycle, giving buyers clear scope and maintenance timing.

The 20-ounce concentrate is intended for a one-tank cleanup across diesel engines, with verified coverage of up to 35 gallons. Its deposit-cleaning claims include internal injector deposits, while the broader system cleaning supports buyers addressing buildup beyond one component. The listing connects restored cetane with improved combustion, cold starting, responsiveness, drivability, and engine noise. It also says regular recommended treatment helps prevent injector sticking and failure, making the product relevant to both cleanup and ongoing injector maintenance.

Skip it if you prefer a listed 5,000-mile treatment interval; Archoil AR6400-D gives that interval or use as needed.

This fits drivers wanting a concentrated cleanup with a stated gallons-treated amount and injector-focused maintenance claims. Its 3,000-mile treatment cycle is a relevant boundary for owners planning less frequent additive use.

#2 · DPF Deposit Focus

2. Archoil AR6400-D Cleaner

Best for: Injector and DPF deposit control.

Why it ranks #2: This 12-ounce cleaner treats 30–40 gallons and specifically targets injector deposits, turbo deposits, and DPF performance.

A single 12-ounce bottle treats 30–40 gallons, giving diesel owners a straightforward tank-pour treatment for injector deposits and DPF-related deposits. Archoil says the cleaner works rapidly and restores injector spray patterns, a combination aimed at smoother running and improved response without a separate cleaning procedure.

Pour the bottle into the fuel tank and drive normally, so treatment fits an ordinary fueling routine rather than requiring special equipment. Its 30–40-gallon coverage gives the owner a defined treatment volume, while the suggested 5,000-mile interval or use as needed helps frame maintenance timing. The formula targets injector deposits and DPF deposits; restoring injector spray patterns is tied to smoother running, response, and combustion efficiency. The listing identifies it as a diesel fuel-system cleaner, not a standalone mechanical repair.

Skip it if you need a large-volume cleaner for stored fuel; Power Service Clear-Diesel Fuel & Tank Cleaner 09280-06 comes in an 80-ounce size.

Choose this for routine tank treatment when injector deposits and DPF deposits are the concerns, and you want a simple pour-and-drive workflow. Keep the 30–40-gallon treatment coverage and suggested 5,000-mile interval in mind.

#3 · Common-Rail Focus

3. BG 245 Diesel Cleaner

• Weight: 1.5 lb

Best for: High-pressure common-rail injectors.

Why it ranks #3: The listed formula cleans the full injection system and is described as especially effective in high-pressure common-rail engines.

BG 245 is specifically identified as especially effective in high-pressure common-rail engines, making that compatibility its clearest buyer distinction. It cleans the entire diesel injection system, including injectors and combustion chambers, while the listing links deposit removal with smoother idle and easier cold starts.

The cleaner removes and dissolves hard deposits throughout the injection system, with supplied details naming both fuel injectors and combustion chambers. That broader cleaning scope is especially relevant to buyers with high-pressure common-rail engines, for which the product is described as particularly effective. The listed benefits—improved cold starting, lower emissions, and smoother idle—connect the cleaning claims to everyday operation. The supplied product information does not give bottle volume or a gallons-treated dose, so dosing plans require the product label.

Skip it if you need a clearly stated 35-gallon treatment dose; Chevron Techron D specifies coverage up to that amount.

This is a relevant option for common-rail owners focused on injector and combustion-chamber deposits, cold starts, and idle quality. The supplied details do not specify treatment volume, which limits dose planning.

#4 · Broad System Cleaning

4. Hot Shot's Secret Diesel Extreme

• Volume: 473 ml
• Weight: 0.45 kg
• Size: 16 Fl Oz (Pack of 1)

Best for: Whole-system deposit and sludge cleaner.

Why it ranks #4: Its listed purpose includes cleaning the entire fuel system and removing deposits, water, and sludge while improving cetane.

Hot Shot’s Secret Diesel Extreme targets deposits, water, and sludge throughout the fuel system, making it the clearest fit here for buyers seeking more than injector cleaning alone. The 16-ounce liquid also improves cetane, connecting system cleaning with smoother combustion, easier starts, and stronger acceleration.

Its whole-system cleaning claim covers deposits, water, and sludge, which makes the product relevant when buyers want a single additive addressing several listed fuel-system concerns. The formula also improves cetane, with the supplied description linking that to smoother, more efficient combustion. Easier starts, stronger acceleration, and reduced emissions are listed performance outcomes. At 16 ounces, it comes as a bottle of liquid additive; the product information does not give a treatment volume, so the exact dose should follow the bottle directions.

Skip it if you need a stated 30–40-gallon dose and injector spray-pattern claims; Archoil AR6400-D provides both details.

Choose Diesel Extreme if deposits, water, and sludge are the concerns and you also value the listed cetane and starting benefits. Its listed bottle size is 16 ounces, but treatment-volume details are not supplied.

#5

5. Liqui Moly Diesel Purge

• Volume: 16.9 fluid oz
• Size: 16.9 Fl Oz (Pack of 2)

Best for: Two-bottle injection-cleaner set.

Why it ranks #5: This injection cleaner is sold as a two-unit set, with each listed unit volume of 16.9 fluid ounces; application details are limited.

Liqui Moly Diesel Purge is listed as an injection cleaner in a set of two 16.9-ounce bottles, giving buyers a clearly specified quantity. The supplied information identifies its purpose and liquid form but does not describe treatment methods, coverage, or particular cleaning outcomes.

The two-bottle set provides a total listed volume of 16.9 ounces per bottle, a useful distinction for buyers comparing package quantity. Its name identifies it as an injection cleaner for diesel, and the specifications confirm a liquid form. However, the supplied product facts do not explain whether it is poured into the tank, how many gallons it treats, or which deposits it targets. Those missing usage details limit workflow planning based solely on this listing and make label directions important.

Skip it if you need stated water-and-sludge removal for stored fuel; Power Service Clear-Diesel Fuel & Tank Cleaner 9264-06 lists those functions.

This suits buyers specifically seeking a Liqui Moly diesel injection-cleaner set with two listed bottles. The supplied facts do not establish its application method or coverage, so consider that information boundary before choosing.

#6

6. Lucas Oil Diesel Deep Clean

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

Best for: Simple 16-ounce bottle option.

Why it ranks #6: The 16-ounce product is explicitly named a diesel deep cleaner, but the supplied listing provides few details about its treatment or target deposits.

Lucas Oil Diesel Deep Clean comes in a straightforward 16-ounce bottle, offering a familiar single-container format for buyers considering a diesel-specific deep-clean product. The supplied listing provides little technical detail beyond the product identity and size, so its appeal is mainly the clearly identified brand and bottle format.

The listing identifies this as Lucas Oil Diesel Deep Clean and includes one 16-ounce bottle, making the product format clear for buyers selecting a single container. Lucas Oil’s supplied brand description says its additives are intended to protect engine parts and support fuel efficiency and power, but it does not provide specific Diesel Deep Clean treatment directions, coverage, or contaminant claims. That limited product-specific information makes it difficult to plan dosing or compare its cleaning scope from the supplied facts alone.

Skip it if you need named injector-cleaning results and treatment coverage; Chevron Techron D states both injector claims and a 35-gallon dose.

This may suit a buyer who wants a Lucas Oil-branded 16-ounce diesel deep-clean bottle. The supplied product-specific details do not establish its dose or cleaning targets, so it is a limited-information choice.

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

#7 · Routine Treatment

7. Hot Shot's Secret EDT

• Volume: 473 ml
• Weight: 16 oz
• Size: 16 Fl Oz Squeeze

Best for: Regular-use cetane treatment.

Why it ranks #7: EDT is positioned for everyday maintenance and lists a cetane increase of up to 7 points, rather than a dedicated deep-clean use.

Cetane improvement of up to seven points is the key distinction of Hot Shot’s Secret Everyday Diesel Treatment, linking the additive to better fuel economy and engine performance. Its everyday-treatment positioning suits diesel owners seeking a recurring maintenance product rather than a cleaner focused chiefly on tank contaminants or sludge.

The listing presents EDT as a regular-use treatment intended to maintain engine health and support smooth, efficient operation. Its stated cetane boost of up to seven points connects the treatment to improved fuel economy and vehicle performance, making it relevant to drivers who want an ongoing additive routine. The 16-ounce liquid comes in a squeeze bottle, a familiar format for adding treatment during maintenance. The supplied details do not specify a gallons-per-bottle dose, so use the product directions for application amounts.

Skip it if you want a cleaner explicitly described as removing water and sludge; Hot Shot’s Secret Diesel Extreme is listed for those contaminants.

This fits diesel owners seeking a recurring additive focused on cetane, fuel economy, and routine engine maintenance. The supplied listing does not state how many gallons one bottle treats, so it offers less dosing detail here.

#8

8. Power Service Clear-Diesel 64 oz

• Volume: 64 fluid oz
• Weight: 4.1 lb
• Size: 64 Fl Oz (Pack of 1)

Best for: Stored-fuel tank maintenance.

Why it ranks #8: Its 64-ounce formula disperses contaminants, removes water and slime, and supports fuel storage stability and corrosion protection.

Long-term fuel stability is the defining feature of Power Service Clear-Diesel, making its 64-ounce bottle relevant to owners maintaining diesel fuel in storage. It disperses contaminants, removes water and slime, and helps protect tanks from corrosion, addressing fuel condition and tank care in one cleaner.

The product’s 64-ounce volume suits buyers seeking a larger container for fuel and tank maintenance, while its listed long-term storage stability directly addresses keeping stored diesel fresh. Removing water and slime and dispersing contaminants connect the cleaner to common fuel-quality concerns identified in the description. It also protects against tank corrosion and helps prevent premature fuel-filter plugging, giving the treatment a maintenance role beyond deposit cleanup. The supplied product details do not state a gallons-treated dose, so application volume needs to come from the label.

Skip it if you need a cleaner explicitly stated to work in all diesel fuels including ULSD and biodiesel; Power Service 09280-06 lists that compatibility.

This is a fit for owners managing stored diesel or addressing water, slime, contaminants, and tank corrosion. Its storage-stability claims are useful, but the supplied details leave treatment volume unspecified.

#9

9. Power Service Clear-Diesel 80 oz

• Weight: 4.85 lb

Best for: Fleet and stored-fuel cleanup.

Why it ranks #9: The 80-ounce tank cleaner addresses water, slime, and contaminants and is described for stabilizing fuel during long-term storage.

Power Service’s 80-ounce Clear-Diesel cleaner pairs contaminant dispersal and water-and-slime removal with long-term fuel stabilization. The listing also specifies use in all diesel fuels, including ULSD and biodiesel, making it a practical option for fleet, marine, or agricultural storage and cleanup workflows.

The 80-ounce size supports buyers handling larger fuel-maintenance tasks, while the fuel-polishing formula disperses contaminants and stabilizes fuel during long-term storage. Removing water and slime addresses the contamination concerns described for diesel fuel, and the product also helps prevent premature filter plugging and protects against tank corrosion. Power Service identifies it for all diesel engines and lists compatibility with ULSD and biodiesel. It can also be used with Bio Kleene during microbial-contamination cleanups to remove residual water and contaminants.

Skip it if you want a compact injector-focused cleaner with a stated 20-ounce size; Chevron Techron D is listed in that format.

This suits fleet, marine, and agricultural users handling stored fuel or contamination cleanup, particularly where ULSD or biodiesel compatibility matters. The 80-ounce size is a consideration for smaller, occasional jobs.

#10

10. Archoil AR6500 Treatment

• Weight: 2.94 lb

Best for: High-volume fill-up treatment.

Why it ranks #10: This 40-ounce treatment handles up to 400 gallons and lists lubricity improvement, injector cleaning, and deposit control, but is positioned for repeated treatment.

One 40-ounce bottle treats up to 400 gallons, giving Archoil AR6500 a clearly stated dosing range for ongoing fill-up use. Its long neck and measuring chamber simplify fuel treatment, while the listing also identifies lubricity improvement, injector cleaning, and deposit control for turbochargers and DPFs.

The measuring chamber and long neck support repeated dosing directly into the tank, while the stated capacity of up to 400 gallons helps owners plan ongoing use across multiple fill-ups. Archoil says it is suitable for diesel vehicles and equipment, including modern HPCR systems, spanning light- and heavy-duty applications as well as pickups, vans, and RVs. A listed ASTM D6079 lubricity test reports a 43% improvement, tying the product to protection of wear-sensitive fuel-system components.

Skip it if you only want a one-time cleaner with a stated 12-ounce dose; Archoil AR6400-D is a smaller tank-treatment option.

Choose AR6500 for repeat fill-up treatment across vehicles or equipment, especially when stated coverage and lubricity matter. Its 40-ounce container and ongoing dosing format are less suited to buyers wanting a single compact treatment.
