AMSOIL now offers an all-in-one diesel fuel additive due to advancements in chemical technology. Our new formula combines the benefits of specialized additives without compromising performance. It effectively addresses detergency, lubricity, anti-gelling, and cetane improvement, meeting customer standards at a competitive price.

Yes, you will. AMSOIL Diesel All-In-One contains the same chemistry found in our individual additives such as Diesel Cetane Boost, Diesel Injector Clean, and Diesel Cold Flow. While Diesel All-In-One boosts cetane up to 4 points, Diesel Cetane Boost can boost cetane up to 8 points.

Yes, you will. The chemistry in AMSOIL Diesel Injector Clean + Cetane Boost mirrors that of Diesel Cetane Boost and Diesel Injector Clean.

There's no significant concern. It's crucial to add the additives before filling the tank and measure accurately. Our treat rates are designed to provide the precise amount needed. Accidental over-treatment is not a major issue, but try to use up most of the fuel before refilling.

No, there isn't. Consistently using the clean-up dose as a maintenance dose won't cause harm.

The detergent and lubricity chemistry are identical. The 8-oz. size has an adjusted treat rate for convenience in smaller fuel tanks. Follow the instructions for best results.

The Cold Filter-Plugging Point (CFPP) test measures the lowest temperature at which a diesel fuel passes through a standardized filter over a 60-second period, simulating cold-weather conditions.

During winter, refiners produce #1 diesel fuel that flows better in cold temperatures, sometimes blending it with #2 fuel and cold-flow improvers. However, if temperatures drop unexpectedly, fuel may not be blended adequately, causing wax-related issues.

Cetane numbers measure a fuel's ignition delay, affecting combustion efficiency. Higher cetane fuels result in improved performance, fuel economy, and startability.
