Mom Misfueled The Picasso

As already said, run it through a basic petrol engine. If it doesn't run, add more petrol until it does.

Diesel fuel pumps and injectors have extremely fine tolerances and require the lubricity of the diesel to prevent wear - any petrol in the mix strips this lubrication and you subsequently generate wear, which is why it is not good to put petrol in modern diesel engines. Petrol engines aren't going to wear out when a lubricating additive (oil, diesel etc) is included in he fuel, but they may not run as well/might run a bit smoky etc. I wouldn't personally put the mix in a modern petrol car but you won't hurt a mower/generator/stump grinder etc.

 

Ok maybe I'll chance it, I was always told that if diesel successfully ignites in a petrol built cylinder it would generate more pressure than the engine could cope with being of a higher potential energy than petrol, and cause damage. Sure theres are loads of pre-fule injection petrol cars around, I have a feeling my neighbour will chance it.

They told you nonsense. Detonation is a result of the compression ratio in this case, not the flash point of the fuel. The CR is fixed. SI CR and spark unlikely to ignite slow burning derv.

Definitely not in a modern petrol car. The diesel would have a good chance of ruining the cat. Any not cat engine is what you need to use in small percentages.

As TCD says not for heating either.

Great idea!

 

LOL, you're determined not to dump it :biggrin:

 

As I said I tried to use it in my mower and while it didn't do it any harm as far as I know it was a nightmare to start and the amount of smoke was unbelievable until it warmed up. In the end it was more grief than it was worth so I'm working my way through it for washing parts/chainsaw chains/bonfires (with care) etc.
