Really Poor Fuel Economy
Really Poor Fuel Economy
Hello there people.
I've been experiencing really bad fuel economy with my MX-3 V6 K8.
I mean like , I put in $20 gas, and I can drive about 150 kms in the city!?
Is that normal for this type of cars, is it the fuel prices that are fooling me, or is there something wrong with my car that I can do about ?
I can't get more than 300 and some kilometers on a full tank in city driving, no matter what kind of gas I put in.
Any input would be appreciated.
Thanks

Assuming the engine has been been given a standard tune-up already, i.e. new plugs, disty cap & rotor, sparkplug ignition wires (if not replaced wothin last 80km), AIR filter, then your O2 sensors might be the culprit - esp. if they haven't been replaced within the last 160km. When the O2 sensors wear out, it means your engine is constantly "guessing" at the accuracy of O2 output in the exhaust stream and this can cause a severe drop in fuel mileage.

sinhron - that sounds pretty normal to me. In my case, a full tank of city driving will last me about 320kms. The absolute MOST I've gotten out of tank by running it dry til it sputtered and died of thirst was 412kms but generally, from the point the "low fuel" light stays on brightly lit to the point where it's filled to the brim and starts overflowing at the opening, I get about 39L of gas in the tank and that lasts me like I said about 320kms. I think the recent jump in gas prices is just messing with you. I just gassed up this past Friday and paid $40.
Mind you though, I don't think the O2 sensors on my car have ever been changed, so if my mileage is less than normal for a V6 running an ATX, somebody let me know and I'll get my O2 sensors changed right away. Right now, I'm sitting at 122,176 kms. Am I due up for a change???

you guys seem to get really shitty gas mileage in my book. With the old K8 i got 28-30 mpg all the time and with the new DE i still get like 27-29 all the time. So I always get over 300 miles to a tank which is 500km's right

I have never passed the 40l mark, the most I've put in was like 39-something
