USP Mineral oil Myths Busted…. again.

Written By Grumpy

No, USP mineral oil is not the same thing as diesel fuel for trucks.

Key Differences

  • Purpose: USP mineral oil is a highly purified, pharmaceutical-grade product used for personal care, laxatives, or food equipment lubrication. Diesel fuel is a refined petroleum distillate designed to combust under high compression inside a diesel engine. [1]

  • Viscosity (Thickness): USP mineral oil is extremely thick and viscous. Diesel fuel has a very thin, watery consistency designed to flow easily through fine fuel injectors.

  • Combustion: USP mineral oil will not ignite properly in a diesel engine's combustion chamber. Pouring it into a diesel fuel tank can clog the fuel system, damage high-pressure fuel injectors, and ruin the engine. Discussions online about using mineral oil as fuel generally refer to experimental or waste oil processing, not pure pharmaceutical USP mineral oil. [1, 2]
