In general unleaded in diesel is worse but it depends on how much unleaded went into how much diesel.
You can't use unleaded in a diesel car.
It depends on the model and the specification of what you have. A car filled with diesel that is supposed to have regular unleaded is not going to run at all.
Diesel fuel injector cleaner will not hurt your unleaded gas motor. The diesel fuel injector cleaner is basically the same as your unleaded injector cleaner.
Look at the fuel nozzle insert. If its green it petrol (unleaded),,,,, black diesel.
You can but you shouldn't use supreme unless the car is specified for supreme and if it is you shouldn't put regular in it.
Unleaded Gasoline, Diesel, Ethanol, or Natural Gas depending on the engine.
Unleaded or Diesel are the most used types of gas.There are a wide variety of fuels used by many different cars. Unleaded gasoline, diesel, E85, and LPG are the most common.
regular 87 unleaded is just fine
Will cause engine damage If large amount in tank car will not start or run
Yes In a modern car changing from regular to premium is no problem It may have been costing you power and fuel mileage to run regular, but if your car does not need premium it is a waste of money. On older cars running regular may damage the engine, but we are talking cars built in the 1980s or older.
The only difference in regular unleaded fuel and super unleaded is the octane rating is higher in super unleaded fuel. Burning super unleaded would not cause your vehicle to die.
Never put gas in a diesel car. And never put diesel in a gas car. An engine is built to handle one and not the other.
