    1 heat range higher as far as plugs are concerned due to engine age.Hotter plug will burn off any excess oil(within limits)and give a slightly better burn of the fuel.Have fitted non resistor plugs NGK V Grooves and had great reults compared to factory fitted resistor types.Also gap the plugs 1 point lower than specification as you get a fatter spark which over time burns off to original specs anyway and equates to more time and use out of them before replacing again.The air filter should be kept clean and if not already done a bottle/can of injector cleaner would help to give a better and more consistant spray pattern.Have the oxygen sensor checked to make sure its operating with in specification because over time it gets covered in contaminants etc and gives the ECU the wrong message.Engine must have no intake leaks.Check around the injector seals with carby cleaner sprayed lightly with engine running,if engine stops or reacts the seals will need replacing as any leaks will make the engine richen up to compensate for poor air/fuel mixture.good luck

Fuel consumption of my mistubishi galant ss 1990


Make sure the air filter is clean,make sure the oxygen sensor is ok but would have to suspect its carboned up due to vehicle age ,if not working properly it tells the engine to run richer than normal.Also make sure the plugs and spark plug leads are in good condition.It wouldnt hurt to put a bottle of injector cleaner in the fuel tank next service as dirty injectors will also add to fuel use.A few small things to do or check but worth it by the sound it.
