The Lineup at a Glance
Diesel 4-IN-1 (ADB) — combines the detergency and lubricity of Diesel Injector Clean, the cold-flow protection of Diesel Cold Flow, and the cetane boost of Cetane Boost in one all-season dose. Lowers CFPP up to 40°F, raises cetane up to 4 points, improves fuel economy up to 8%.
Diesel Injector Clean + Cetane Boost (ADS) — warm-weather combined protection: detergency, lubricity, and up to 8-point cetane increase. Pair with Diesel Cold Flow in winter, or switch to Diesel 4-IN-1 for year-round convenience.
Diesel Injector Clean (ADF / ADFP) — targeted injector cleaning and ULSD lubricity. Cleans internal diesel injector deposits and traditional carbonaceous deposits. Helps prolong time between EGR and DPF regenerations.
Diesel Cetane Boost (ACB) — targeted cetane booster. Raises cetane up to 8 points for maximum horsepower, better fuel economy, and easier starts. Compatible with DPFs.
Diesel Cold Flow (ADD) — targeted winter protection. Lowers CFPP up to 40°F in ULSD, prevents wax settling, inhibits fuel-filter icing. Must be added above the cloud point.
Diesel Recovery (DRC) — emergency treatment. Dissolves wax crystals in already-gelled fuel and thaws frozen fuel filters. One 30-oz bottle treats up to 30 gallons.
Applications
All AMSOIL diesel fuel additives are formulated for heavy- and light-duty, on- or off-road, and marine diesel engines. Safe for use in all diesel fuels including biodiesel and ULSD. The cetane, injector-clean, and combined products are compatible with diesel particulate filters (DPFs) and other modern exhaust emission systems.
Preventive additives (Diesel 4-IN-1, Diesel Cold Flow, Diesel Injector Clean + Cetane Boost, Diesel Injector Clean, Diesel Cetane Boost) must be added before filling the tank and above the diesel fuel cloud point. They will not reverse gel or wax crystals once formed — for that situation, use Diesel Recovery.
