Power Service Diesel Kleen +Cetane Boost

Most diesel owners don't realize the fuel going into their tank is working against them. Here's why that matters.

When refiners remove sulfur to produce Ultra Low Sulfur Diesel — the only diesel legally sold in the US — that process also strips the fuel's natural lubricity. The components relying on that fuel for lubrication, your injectors and fuel pump, now operate with tolerances measured in microns and reduced protection. On top of that, the national average cetane number of ULSD runs between 47 and 48. The Engine Manufacturers Association says diesel engines operate better above 50. Most tanks are running below the target every single fill-up.

Diesel Kleen addresses both problems directly. Three things it's actually doing:

First, cetane. It boosts cetane up to 6 numbers — which means most tanks will hit the 50+ target with one treatment. Smoother combustion, less power lag, faster cold starts.

Second, lubricity. The Slickdiesel Lubricator formula exceeds the HFRR wear scar specification and their own lab data shows a 160-point improvement in wear scar diameter from untreated to treated fuel. That's a documented number from their technical lab, not a marketing claim.

Third, injector cleaning. It removes both internal and external deposits and prevents injector sticking in High Pressure Common Rail systems and older legacy systems.

One more thing worth knowing — this is the only fuel injector cleaner endorsed by Cummins, the largest diesel engine manufacturer in the world.

How to Use

Add the bottle to your tank before you pump — the fuel filling in naturally mixes it for you. Power Service's directions call for the entire 16 oz bottle per 40 gallons for maintenance, or 20 gallons if you're doing a first-time clean-up on a neglected engine.

Use it every fill-up for ongoing protection. This is a maintenance product, not a one-time fix.

Not for: Gasoline engines. Diesel only. Also — do not add to the DEF tank. This goes in the fuel only. In Florida we don't worry about cold weather gelling, but if you're traveling north in winter below 30°F, switch to the white bottle — Diesel Fuel Supplement +Cetane Boost — for freeze protection.

Who needs this: Anyone running a diesel engine. Trucks, vans, boats, farm equipment, generators. ULSD fuel is a compromise the refiners made to meet emissions standards. This is how you compensate for it.
