8th Gen Civic - Concerns on fuel economy

[andyhui01]

I've been averaging low to high 8l/100km and on a recent trip to Mt. Buller, did 8l/100km even with all that overtaking and a couple of redline's on the B-roads... but I'm still not getting 500k's on a tank... nowhere close when I'm in the city, only do about 400-420km's and I'll refuel (2-3 bars left).

any1 have the sports so I can compare mine with?

If your fuel guage is as accurate as mine, with 3 bars left you still have at least 100 km to go. I recently travelled 30km with no bars showing, yet it took 43 lts to fill it to the brim. bear in mind it is a 50 liter tank.

Finally we agreeing on sumthing here buddah my mate Vti was running around 100kms with 3 bars left and the car finnaly stop just when he about to enter the petrol station

so his gauge reads differently to mine, but that is not uncommon. wether u agree with me or not is your decision, but after 38 yrs as a mechanic owning & working on hondas since 1989, i think i know a little bit

I have done about 50klms with no lights opn the gauge and still had about 5 litres left in the tank which is great

I would like to share with everyone my fuel consumption figures for the last 9 weeks. All of this on standard unleaded fuel from my local woolworths station. I dont believe i nurse the car, mostly the cruise control is set 3 or 4 kph above whatever the limit is. Once a week the car is redlined in 1st & 2nd to give it a good run.

Distance travelled liters used consumption

640km 44.5 lts 6.67 L/100km

[buddah51au]

try again with the next 8 weeks

549km....37.04 lts......6.75 L/100km
553km....37.62 lts......6.80 L/100km
517km....35.62 lts......6.89 L/100km
496km....34.28 lts......6.51 L/100km
485km....33.33 lts......6.87 L/100km
524km....36.59 lts......6.98 L/100km
444km....29.62 lts......6.67 L/100km
439km....29.30 lts......6.67 L/100km

Remarkable figures i think and very consistent.

hey buddah... I need your help for this... will turning cruise control on more often consume more fuel? How about Paddle Shift?

just fill in my 06 Auto Sports again yesterday, driving without ever pass the 3,000 rpm last week using padle shift (and randomly mix with auto driving + cruise control on highway).

Consume 35.12L for 332kms...

snd me a private message with your email address. I believe there are definately a few tricks involved in achieving the figures i do and it definately requires a certain driving style. I also found the only way to achieve accurate figures is....as much as possible fill your tank using the same pump bouser each time so the angle of the car doesn't vary....the angle of the car when u fill it can make a difference of 2 or 3 liters, and on a small tank this omount of discrepancy makes a lot of difference to the figures achieved.
On a side note, i am looking forward to doing a trip to sydney 1 day, 1500km of which 1/2 of that distance will be flat open country......i will be disappointed if i dont average under 6L/100k....everything points in that diection in my opinion.
example.....previous car....EF Fairmont....weekly commute ave 10.8L/100....dropping to an average of 9.1 on a trip to sydney

thanks buddah... you've got pm! ^_^

For the last 10 weeks i have been experimenting with filling at the same bouser each time, so that the car is in the exact same position each time it is filled up. I am now certain this is absolutely vital to get accurate readings (plus or minus 1 liter makes a big difference in gauging fuel ecconomy, especially with a small fuel tank). The end result of this is that the weekly results have been very consistant ( a best of 6.51 l/100 & a worst of 6.98
l/100, average over 10 weeks = 5,044km - 343.08 lts = 6.8 l/100km).

My next experiment, if i can ever get the courage to do it, is to let the wife use the car for a week to see how much difference there would be between different driving styles on the same roads.......that could be an interesting result. If it ever happens i will post the result, but for now i think i have posted enough on this subject.
