GrannyGranny Posted September 21, 2011 Share Posted September 21, 2011 That is complete rubbish! its the other way around. If you put petrol in a diesel engine just fill to the top with diesel and car may run like **** for a while but will be ok once all fuel used up. if you put diesel into a petrol car you would knacker the engine! Not always true as petrol in diesel acts as a solvent and can damage the fueling system. See below taken directly from the AA website. "Petrol in Diesel Do not turn on the ignition or start the car If the car's still under warranty check with the franchised dealer regarding their advice and correct remedial action – running with even a small amount of petrol in the tank might invalidate the warranty. Some manufacturers advise that you should get seals and filters renewed even if the engine has not been run. Generally a small amount of incorrect fuel should not damage the engine as long as you have not started the car and top up fully with diesel. If you've added more than 5 litres of petrol – Drain the tank and refill with diesel If you've added less than 5 litres of petrol – Top up with diesel and run normally unless the manufacturer has advised otherwise Diesel in Petrol Do not turn on the ignition or start the car This is less common because the standard diesel nozzle is bigger than the filler neck on modern petrol cars – you have to be pretty determined and patient to misfuel with diesel.

The petrol will damage the seals in a modern common rail diesel engine's fuel system...the diesel is used as a lubricant for the fuel pump etc...
