Diesels are more efficient than gasoline engines because of the way engine speed is controlled (diesels control speed with the amount of fuel injected, whereas gasoline engines control speed by how much air gets in), and because diesel fuel contains more chemical energy than gasoline.
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.
One of the main advantage of using a Diesel engine as opposed to a regular is that a Diesel engine tends to burn less fuel. They also have very high thermal efficiency.
Rudolph Diesel invented the diesel engine which uses diesel gas.
The advantage is that electric cars don't pollute and doesn't use fuel (gas, diesel, etc). But the thing is it can't go the distance of a gas engine or a hybrid.
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.
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.
In a gasoline engine, definitely not. There are times when it is not inappropriate to add small amounts of gasoline to diesel for a diesel engine.
you will have a bomb. your engine could explode from the increased compression of a diesel engine
EGR stands for "Exhaust Gas Recirculation". the 7.3 is a Diesel engine not a Gas engine. Diesel engines are not equipped with an EGR.
