Gas / Diesel contamination
If I used a gas can with a small amount of remaining gasoline (less then a few ounces) and filled the can with diesel, would the small amount of gasoline damage my engine?

Had a gas station attendant put a between 1/2 to a gallon of gas in our 2001 Ram CTD, just finished fill with diesel and all was good.
Been driving diesel since 2001, and this right here is why I never allow anyone else to fuel up my ride. Despite telling the gas jockey to add diesel, and the gas cap having "Diesel Only" printed in the biggest letters possible, and the restrictor plate in our newest diesel vehicle that is supposed to make it impossible to insert a gas nozzle, idiots abound, and the various diesel forums are full of gas jocks managing to fill up with gas and then the engine blew up.
Somebody always whines "but here in New Jersey/Oregon we're not allowed to fuel our own cars." True, if your car burns gas, but the laws in both states exempt diesel. If your ride burns diesel, you ARE allowed to fuel them yourself, although many gas jockeys do not know that and will give you an argument anyway.
So, yes, you CAN get away with a SMALL amount of gas in your tank, provided it contains a LOT of diesel. But it is not good practice, and there is a threshold gas concentration at which really expensive bad things happen very quickly.
