Diesel enthusiasts and hard-working professionals who depend on their diesel vehicles have a lot on the line when temperatures drop.

Winter temperatures and diesel fuel quality are both variable. Increased protection against cold-temperature gelling provides the confidence that you’re avoiding the headaches, costs and dangers associated with your fuel gelling when the temperature drops.

Prevent diesel gelling

AMSOIL Diesel All-In-One boosts cetane by up to four points to provide better protection against cold-temperature gelling. Cetane plays a key role in achieving maximum diesel power and efficiency and helps ensure rapid smooth starting in cold temperatures.

There are many diesel fuel treatments on the market, but AMSOIL competes head-to-head with the leading diesel fuel additives. We start with the most advanced additive technology and engineer additional protection that goes beyond what the leading brands provide.

In lab testing, AMSOIL Diesel All-In-One was added to two samples of No. 2 diesel fuel and placed in a blast freezer. When the temperature dropped, AMSOIL Diesel All-In-One went to work preventing wax crystals from forming and allowing fuel to flow freely in subzero temperatures.


Cold-temperature protection

  • Lowers cold filter-plugging point (CFPP) by up to 40°F (22°C)
  • Enhances engine reliability in cold temperatures
  • Improves low-temperature startability
  • Prevents wax settling during storage


Improve fuel quality
