Power Service Diesel Kleen + Cetane Boost 64oz (6 Pack) - Cleaner

In this review of the Power Service Diesel Kleen + Cetane Boost 64oz 6 pack, the bottom line is simple: this is a practical injector cleaner and cetane improver for diesel owners who want smoother starts and recovered power. The reviewer found it most valuable for vehicles and equipment that have accumulated injector deposits or that run on modern ULSD and biodiesel blends. Used as a regular treatment, the product tackles sticky injectors and helps engines run with less lag, making it a straightforward maintenance add-on rather than a complicated repair.

Key Features

• Cleans injectors: Formulated to remove deposits and prevent injector sticking in both HPCR and older systems so combustion is more consistent.
• Boosts cetane: Raises cetane up to six numbers which helps engines idle smoother, reduces power lag and improves cold starting.
• Broad fuel compatibility: Effective in all diesel fuels including ULSD, biodiesel and biodiesel blends, so it works across a wide range of tanks.
• Lubricates injection components: Adds lubricity to the fuel system to protect pumps and injectors without changing normal service routines.
• Universal fit: Packaged for universal use across diesel applications, making it easy to add to cars, trucks and off-road equipment.

Who It's For

Diesel Kleen + Cetane Boost is best for owners of diesel cars, light trucks and equipment who experience rough running, sluggish throttle response, or harder cold starts and who want an easy, periodic treatment that addresses injector deposits and cetane level. It is also a sensible preventive maintenance product for those using ULSD or biodiesel blends who want to restore lost power and fuel economy.

It is less appropriate for someone seeking a dedicated winter-flow antifreeze or antigel; the label notes that below about +30F a winter-specific supplement should be used. Buyers who need a diesel winterizer should consider a product formulated specifically for cold protection.

Pros & Cons

Pros

• Effective injector cleaning and prevention of sticking across HPCR and older systems.
• Noticeable improvement in cold starts and throttle response after treatment thanks to higher cetane.
• Works with ULSD and biodiesel blends, offering broad compatibility.
• Good value in a 6 pack for regular maintenance intervals.

Cons

• Not intended as a winter diesel antifreeze or antigel below approximately +30F, so requires a separate winter product in cold climates.
• Benefits depend on condition of fuel system; severely degraded injectors or mechanical faults will need service beyond an additive.
