The Technical Hazards of Petrol in a Diesel Engine

Diesel fuel acts as a lubricant for high-pressure fuel pumps operating at up to 30,000 PSI. Petrol is a solvent that strips lubrication immediately upon contact. Running petrol through a diesel pump creates micro-friction shavings that spread into high-cost fuel injectors.
