Hello guys,

My vehicle used to take 18L/100km (13MPG).
I have replaced the O2 sensor and the catalytic Converter (the engine light was ON) and after that the gas consumption changed to 11.4L/100km (20MPG).
Yesterday I filled the tank (46L of gas) and now the Bord Computer shows me 23.2L/100km (10.1 MPG).

What is normal for a 2.5L X-Type. How much you guys get?

And I would like to know please: is there any adjustment that needs to be done in order to make it better?
Reflash the computer sofware maybe? Something?

Thank you in advance!

 

Sounds VERY low. I get almost 22MPG in my 3.0. That is MEASURED, not what the on board computer says--the on board computer tends to show better fuel milage than if you calculate it yourself.

 

It is something that can be done?

 

Tracus, with my X-type (3.0L motor), I pull on average about 22/23 mpg. I have noticed that if I drive the car hard, it is really easy to pull the mileage down to 20 mpg. The other thing I have noticed with the car is that it doesn't like idling in stop/go traffic. If I sit in traffic for say 30 minutes, I can see a 1-2 mpg drop in my mileage from the whole tank.

All that I can say to try is to first check the accuracy of your trip computer. You can do this simply by filling the tank till it is full (ie, the pump turns itself off) and then drive till you are down to around 1/4 tank (lower if you are confident that you won't run out of fuel/petrol) and then refill. Then hand calculate the mileage and see if it is close to what the computer says. If it is not close, then you may have a bigger issue. It should be fairly close. Then you can get out on the highway and as you are driving at say 65 mph (120 km/hr), reset the trip computer and let the display come to a fairly constant value. In most cases, you should be able to get above 24 mpg, if not up around 26/27 mpg. if you can get above 24 mpg, then your engine is running fine and odds are the low mileage is a function of accelerating hard from being stopped or doing a lot of in town driving. The variable valve timing is great for low end power, but can also be hard on the mileage when spending a lot of time in town.

 

Ok, Thermo, I will do that and I will let you know how it goes.
Thank You!

 

With my 04 3.0L I see an average of about 20-21mpg with about 60% street 40% highway driving and sport mode turned on all the time. I haven't been on a long drive for a while but i would expect to see over 25mpg

 

Tracus you can expect anywhere from 20 to 25mpg depending on your driving style and terrain. I get around 24.5 to 25.5 in mixed driving, 70% highway, with my 2.5 running premium. Sport button off on the highway, on when on 2 lanes.

 

03 2.5 we get around 24-25.

 

I have a 2.5 '02 X-Type. I did about three tank fulls almost strictly on the highway and the computer told me I was getting 26mpg. I the past 11 days I've driven 750 miles 90% street and I'm at 20.2mpg. But I'm normally at 22.5mpg and that probably 45% highway and 55% street.

 

I get 25 highway and poop in the city. I average 19 mpg with mixed city/highway. I did a test today and found out that with the sun roof open i get 3-5 less mpg then with it closed.

 

When I lived in MI I averaged no lower than 20mpg a tank (3.0 sport with both 17's and 18's.) Most I ever got on trip doing 80-85 with an average speed of around 75mph for the tank was just under 25mpg. Driving to my parents with a few stops and coming back home I could get 26-28mpg but that changed when I did my usual driving which consisted of letting the car warm up until the idle dropped to warm idle and driving for a couple of miles shutting the car off and repeating the same situation over and over. I usually averaged over 20mpg under those conditions.

When I moved to TX I averaged around 16-18mpg since all the driving was start/stop and never really drove very far. The car spent more time idling, starting/stopping than it ever did moving.

Your car should never drop below 20mpg if your car sees more highway than city driving.

IIRC you could reset the trip computer by removing the battery cable from the battery but I can't say for sure. This also resets all the other features on your car like the auto windows so keep that in mind.

 

I usually average 19-22 mpg mixed driving, depending on how I am on the gas. I have got as high as 27-29 mpg with mostly highway use going on trips for work.

 

I am getting 18mpg so far in conformity with the trip computer.
I did not refill yet but I will let you know how is working. So far I used the vehicle only in city driving.

 

I live in Chicago so more city driving than highway. I log all my gas (more for tracking work expenses) and in 58,800 miles I am averaging 19.5. My highest is 25.3 and my lowest was 14.2 (this was in VERY cold weather). I am not easy on the throttle so I am sure others can do better.

 

2004 3.0 AWD

I run premium (91 and sometimes 93) and I never see mileage lower that 18 or 19 in hard city driving with the trans in sport mode. On the highway I get between 24 and 26. The new O2 sensor might need some adjustment.

When I calculate my own mileage, it's usually 1 or 2 mpg lower than what the computer says.

 

Thank you everyone for your reply.
cward11, I am getting the same except mine is a 2.5.
So is ok so far... hm
I wonder if it is some adjustment that can be done regarding this...

 

My 2002 2.5 has settled in the last few months at 24.5 in mixed driving, 70% highway.

 

lucky you man. Unfortunatelly I am driving only town. However, as soon as I drive outside and keep it arround 90 km/h to 110 km/h I am getting 25mpg.

 

hi everyone i have a 2001 2.5 auto petrol and around town i get between 18 to 20 per gallon, does that sound about how it should be

 

>90 km/h to 110 km/h I am getting 25mpg.

Would that be in Imperial or a US gallons?
