Bad Diesel Mpg

[Rash]

Hi All,

Recently bought an 1992 corolla diesel (import) with 40K mileage which has high fuel consumption. I changed the fuel filter, oil filter, air filter and oil. The corolla has an auto gearbox.

The MPG is about 28. Any ideas why the MPG is so low or is this typical. Also, I would be grateful if someone can forward me timing data information.

Thanks in advance.

im not too sure m8 but you allways try resetting the ecu. worked on my old corsa. just take disconnect the positive Battery wire for 1 hour. recconect it and start the car.

the engine will be a bit rough for the first few minutes of running, just let it settle as the ecu is resetting during this rough idle.

id only use this as a last resort tho. there may be better answers by otheres lol.

Try an injector cleaner too.
