Decreasing efficiency?

ruracer · 25th July 2007, 21:46

Is anyone experiencing a decrease in efficiency?
My car has done 1400kms. This is the first time that my tank efficiency figure, trip A, is higher(worse) than my counting since new, B trip efficiency figure.

The trip A is at 350kms and the B trip at 1400kms.
Ive also noticed or Im imagining it, that as the fuel gets closer to running out that the fuel efficieny figure statrs to get worse even though driving style and roads used havent changed....

No power loss, no oil used. Car is really loosening up now, every 100kms makes a difference.

What do you think?

I think that as the cars start to loosen up & we get used to them, we then start to drive them a little harder. I have noticed the same 'symtoms' with the fuel economy

I agree with that! My MPG gets worst and worst since I have my car!

(but driving is more and more fun...

My MPG is nowhere near the possible figures but again thats most likely down to me, I suspect the same could be true of your own findings.

ah ha! so im not crazy.... so after the next reset ill drive like a granny again, and see if i can get as low as 6.2L/100KM as i did before on my work trip of 32kms.

Mine did improve after 10 000 Km ... Before it was a little bit erratic from one refuelling to another. It's very sensitive to "start and go"...

I have already tried that also but after 1-2 miles or so... back to 3rd then REV lights, 4th...

and I gave a s... on the economy! back to "funmode"!

The higher temperatures we have been experiencing the last 2 or 3 days will have affected the fuel consumption slightly as well.

well, ive filled up again and driven normally,and figures were about 7.2 till tank reached below half way point, then fuel economy started to get worse. I noticed this before too, it gets worse as the fuel thats in the tank gets less......now it reads about 7.7????

but i just think now that the computer reader is inaccurate anyway,at the start of the tank, it read 21.5, 10 seconds later read 12.4,and eventually settled on a 7.x
so whatever.... i reckon im gettin roughly 40mpg.
Case closed.

My 2.2 is easily exceeding my expectations ;46-48 mpg town(flowing) driving with a bit of open road thrown in;58-60 mpg mostly motorway at indicated 75-80 mph.

my previous Alfa 159 2.4jtdm was giving approx 31mpg town and 36-38 mpg motorway.The car,with its 200 bhp,was more lethargic

around town compared to the civic,and on the open road the Civic I would say,about compares (once the Alfa is above 50 mph it starts to wake up)

The Civic really does give you the best of both worlds
