HOT – Heating Oil Treatment

HOT 4 in 1 is the best at:
  • Dispersing water. 
    HOT 4 in 1 disperses any normal accumulation of water in a tank, turning it into a combustible solution.
  • Getting rid of sludge. 
    HOT 4 in 1's specially formulated chemical base dissolves the sludge into a combustible substance in such a way as not to clog nozzles while assuring clean filters and strainers.
  • Improving atomization and reducing soot. 
    HOT 4 in 1 eliminates sludge so the fuel oil reaching the nozzles is clean. This will mean improved atomization takes place and soot is reduced substantially. Ultimately resulting in more complete combustion, less smoke and better fuel economy.
  • Preventing waxing and gelling. 
    HOT 4 in 1 will disperse the water that causes fuel line and fuel filter icing. Also during the coldest days of winter, fuel oil in outdoor tanks can cease to flow. The reason is paraffin wax, always present in fuel oil, develops crystals when the fuel oil reaches it's "cloud point" temperature. When these crystals are totally formed at the "pour point" temperature, the fuel oil ceases to flow. HOT 4 in 1 will lower the cold filter plug point (CFPP) and the pour point of fuel and will prevent waxing and gelling.
BIG OAT’S offers the best prices in the area on Power Service products, whether for your fleet, farm or personal vehicles you won’t find a better price anywhere. If for some reason you do, let us know and we will beat it.


Diesel Fuel Supplement + Cetane Boost
  • Prevents fuel gelling in temperatures as low as -40°
  • Equals performance of a 50/50 blend of No.1 and No. 2 diesel fuels
  • Lowers Cold-Filter Plugging Point (CFPP) as much as 36° - keeps fuel filters from plugging with was
  • Boosts cetane up to 4 numbers faster cold starts
  • Contains anti-icing additives – protects against fuel-filter icing
  • Contains wax anti-settling dispersants – protects against fuel-filter plugging at temperatures below the fuel cloud point
  • Contains slickdiesel for maximum fuel lubrication – protects fuel injectors and pumps against accelerated wear from Low and Ultra Low Sulfur Diesel (ULDS) fuels
  • Boosts Power – reduces need for downshifting during high-load conditions
  • Disperses water in diesel fuel
  • Effective in all diesel fuels, including ULSD and biodiesel blends containing up to 20% biodiesel (B20)

Diesel 911 For Winter Emergencies
  • De-ices frozen fuel filters
  • Prevents fuel-filter icing
  • Reliquefies gelled fuel in minutes

  • Effective in all diesel fuels, including ULSD and biodiesel blends containing up to 20% biodiesel (B20)
Diesel Kleen + Cetane Boost
  • Cleans dirty injectors – including High Pressure Common Rail (HPCR) injectors
  • Boosts cetane up to 6 numbers – engines run smoother with less power lag and faster cold starts
  • Decreases fuel consumption up to 8% - fuel savings exceed cost of additive
  • Boosts Power – reduces need for downshifting during high-load conditions
  • Contains Slickdiesel for maximum fuel lubrication – protects fuel injectors and pumps against accelerated wear from Low and Ultra Low Sulfur Diesel fuels
  • Prevents thermal/oxidative breakdown of diesel fuel – protects against sludge formation that plugs fuel-filters and injectors
  • Stabilizes stored fuel

  • Effective as a "quick-kill” biocide and for long-term diesel fuel and maintenance
  • Kills microbes (bacteria and fungi) that grow in dispersed and free water associated with diesel fuels
  • Presents fuel-filter plugging – helps prevent fuel system failures
  • Protects fuel system components against organic acids created by microbial growth – prevents fuel tank corrosion
  • Improves fuel performance
  • Reduces engine maintenance costs
  • Burns similarly to diesel fuel (>106,000 BTU/Gal)
  • Ultra Low Sulfur Diesel (ULSD) compliant – contains less than 15 parts per million (ppm) sulfur
