my 79' gets 24-28 MPG but I am pretty sure that the last owner didn't time it properly
How do you change fuel filter on peugeot 806 diesel?
diesel.
If its a Diesel, its probably the Diesel Stop switch. Located on the Diesel Fuel Pump.
Better mileage
Under the fuel filter housing
how do you take clips off
Probably the best way to get better fuel mileage would be to get a tuner for it.
According to my manual, the fuel light goes on when the tank is down to approx 6 litres of diesel.
10-18
Diesel will always give you better fuel mileage as diesel fuel itself contains more BTU (the measure of thermal energy) in a given quantity than compared to gas.So therefore a diesel engine can extract more mileage out of a gallon of diesel fuel as there is more energy to extract out of that gallon as compared to a gallon of gas.Considering this, this is why diesel fuel prices would have to rise considerably over gas before the two would be equal on a cost per mile basis.
Diesel engines normally get better fuel economy than gasoline engines.
Keeping up with scheduled maintenance, better driving habits... a lot's been done since ACERT went into effect in the early 2000s which has impaired fuel mileage... EGRs decreased fuel mileage, SCR/DPF/DEF decreases fuel mileage, 2007 introduced Ultra Low Sulphur Diesel - which is a less efficient fuel than the previous low sulphur diese - all in the name of emissions. Turbocharging remains the best option to improve diesel efficiency.
