Will petrol damage a diesel engine?
It can, if the engine is started and run, because petrol strips the lubrication the diesel pump and injectors rely on. Caught before starting, a drain and flush almost always prevents damage.
In an emergency: don't start the engine and call 0800 170 0644. We drain the wrong fuel on-site, 24/7, 365 days a year.
