it has a little handpump to priam diesel back to injectors under the bonnet
Gasoline engines cannot run on diesel. Only a diesel engine can run diesel. And a diesel engine cannot run on gasoline.
Only if you have time to fix the resulting non running mess. Diesel fuel, no. Diesel engine oil, yes if it is the proper weight.
The engine would stop running. You would need to drain the gas tank. If the engine has been allowed to run since the diesel was added you would also need to drain the fuel line.
No you can not use gas engine oil in diesel engine oil because processing of diesel engine is different from gas engine oil. If you use this then it damage your vehicles.
Do NOT use Diesel fuel in a Ford Focus. The engine will stop running and you will have to drain the gas tank to rid the car of the diesel fuel. Gasoline engines are not designed to run on diesel. They do not have enough compression to cause the diesel fuel to combust The only engine used in a 2000 Ford Focus was the 2.0 which is NOT a diesel engine.
Rudolph Diesel invented the diesel engine which uses diesel gas.
gas
That is a GAS engine.
You'd need to swap in a gas engine. A lot of people believe that the Oldsmobile 5.7 LF9 diesel was a gas engine converted into a diesel - this is simply not true.
Compared to heavy industry, no. Compared to gas, propane, etc, engines, yes. The draw back from using diesel engines is they put out the most "Heavy" particulates then a gas engine. ALL vehicles have soot/heavy particulates. With the newer diesels it has become less of a problem. The upside of running a diesel is you get more power/torque from a diesel then a gasoline engine. More bang for your buck.
if it is diesel a duramax diesel if its gas it will be a duramax
No, you cannot convert a gas engine to a diesel engine. A diesel requires much stronger parts.
