1989 A90Q gas mileage

[Gwen Agboat]

Hi everyone,

 

I had some work done on the engine and the car ran really well.  The
mechanic asked me to bring it back in to have the oil changed and "set" the
engine.  Ever since this was done. my gas mileage is awful.  I'm lucky if I
can get 425 Kilometers from 50 liters of highest premium gas.

 

Any suggestions on what might cause such poor gas mileage suddenly?  I can
smell the exhaust when I start the car and stand about 8 feet away from the
car.

 

Thanks,

 

Gwen
