Fuel Economy question

03-23-2005, 10:04 PM
Hi all
95 Mystique with 2.5L engine. Runs good, had some problems with engine check light, turned out to be bad/corroded contact in O2 sensor harness. I make around 300 - 320km on a tank of gas mostly city driving. I refill the tank when it comes less than the last quarter left. I believe it was 45L for this distance. Does this seem normal, low, high? Just want to have a feel what to expect.
There was also a lean condition code before I cleaned the O2 connectors. Now it does not come on any more. When it was in for cat replacement they said intake manifold is leaking. This may affect fuel economy. I'll replace it and clean intake when it gets warmer.

Well, I have a 97' mystique 2.5 liter and I can not complain. I do the same as you I refill the tank when it gets to a quarter of a tank left. If you would put the 300-320km on a tank in miles per gallon I might be able to help more. I dont understand the km I would understand if you said like it gets 32 miles per gallon. peace.
