How Desl-Shok® Works

Desl-Shok® is a premium-grade, multi-function fuel additive for 2- and 4-stroke diesel engines, formulated for regular, low-sulfur, and ultra-low-sulfur diesel.

It provides a high level of protection against condensation build-up in fuel tanks — reported to be the root cause of more than 70% of engine failures. It keeps injectors and fuel lines clean, and promotes a cleaner-burning fuel that reduces carbon build-up in engines and exhaust systems.

One broad-spectrum formula doing five jobs: water dispersant, stabilizer, lubricant, cleaner, and combustion enhancer.

Features & Benefits

  • Controls and disperses water in fuel tanks and fuel systems
  • Reduces smoke and engine noise
  • Restores fuel economy lost to carbon-fouled rings, valves, and injectors
  • Stabilizes all diesel fuels, including low-sulfur and ultra-low-sulfur
  • Adds lubrication to extend fuel pump and injector life

What It’s For
