Thread: Diesel hilux with 10L petrol in it?

Unusual for a Diesel engine to over-rev on a petrol/diesel mix. They generally smoke, make poor power and stall out. If they do continue to run the engine will often seize pistons in cylinders because of lack of lubrication properties of diesel fuel. The petrol doesn’t burn properly as it relies on the ignition of the diesel due to compression pressure and burns as a secondary flame in basic terms.
