High Fuel Consumption

[aido]

1000 miles - that trip would cost me 300 quid for what I get around town, reckon I could do it for 150 if it was all motorway!

My car has been goosed and the last 40 quid got me 70 miles :o

No wonder I'm thinking of getting a supermini diesel next

Had to pop a tenner in the tank today until Tuesday next week as I'm not doing much mileage until then. Managed to get 340 from the full take, so, calculating that works out at:

25.9

Much better than last time :)

I get about 300-350 miles from a full tank at best. I've got Denso IK20 plugs and a K&N panel filter, the car has had regular servicing and the mileage is only 40k.

I find it great upto 85mph, after that it just guzzles fuel. Does anybody else find the same ?

Oh and in the past I've found that just one tyre being under inflated has a major effect on the fuel consuption, much more so than on other cars I've had.

Yebbut there's something wrong with yours mate. Even if I drove everywhere like a loon, I'd hope to get more than 70 miles from 40 quids worth of fuel! That's about 7mpg!!!

Get yourself a 430, most of the performance of yours with much better economy! Never thought I'd recommend a V8 based on it's economy though!

[aido]

Yeah mate it was battered, fixed now though I hope :D

After all that messing about was a crack in the plastic assembly, lots of microtears which I guess were releasing pressure and then eventually it's totally given in!

Will get a pic up later - hopefully it should be a bit better now but I'm not really going to be using the car for the next week or so!

Just wish I'd taken a look at lot earlier at the engine bay, never bothered as I'd just got it in my head it was a coilpack, what a plonker!

Anyone got a calcu-m-a-lator?

Last put £30 quid in- approx 30 litres and got 128 miles out of it.

Wadda ya reckon?

Deal or no deal??

[Ian M]

Sub 20mpg. No deal!

use spiritmonitor.de

nice little site that calculates your mileage for you

Well I had sticky brakes going down to Glossop so i wont count that but got them fixed by Steve.

Now i filled my tank on the way home and drove around town the last few days and i have got just under 400 miles until the light came on.

Now this was on superunleaded i think it was a texaco garage i filled up at and i have an induction and IK20's.

So all in all a RESULT!!! I am happy with that.

P.s. and remember i was trying to keep up with Rogue all the way home and this was not sitting at a cruising speed and was up and down like a hookers drawers

[Vyker]

thats not bad 400miles out of 60ltrs [70lts tank, but light comes on with 10lt left]

after some maths, that means you are hitting.... exactly 30mpg

stick that into spiritmonitor.de .... and get yourself a nice forum logo to stick in your signature.. like my empty one below [not added any data yet]

Thats awful - what sort of driving are you doing?!

[trevman]

Just out of interest, you guys with manual's, at roughly how many revs do you change gear ?

[Continunity]

6500 :D

no wonder i get crappy MPG

[boddamloon]

depends but if im driving normal i guess 4500-5000 RPM

[j_jazzy777]

4000-5000 rpm.

Normal, sedate driving. I have 3 things left to explore before I give up and flog the car:-

1. Empty the boot of my "emergency equipment" i.e. blankets, foam for flat tyre, petrol can, spare oil, tools, football, astro turf boots, brake fluid, bulbs.

2. Over-inflate the tyres- one bloke reputedly did this and got fantastic mpg, and told the Lexus garage not to touch the tyres because he gets such good mpg as a result. I'm guessing you wear your tread out quicker though.

3. Get a full geometry done at WIM- which is long overdue, due to financial constraints.

If anyone has any other suggestions, I'm all ears.(@¦ 0 0 ¦@)

Just did my first mpg check and I am getting around 28 mpg (IS200 SE Manual, 2001 80K). Mostly pottering around with only one long run. I was quite pleased with that as most of the time my mpg guage seems to hover around 20! I was using Shell V-Power unleaded.

[stuie]

without using snow mode I get about 18 mpg when using snow mode I can see over 25mpg around town. Ive come to the conclusion its me being a bit heavy footed in start stop traffic. Managed to get over 35mpg on long runs so I know it can do it

[j_jazzy777]

Hmmm.. seems mpg is a really variable thing. Right across the board there are many different views of what is "normal" mpg.

Well, I've inflated all four tyres to 40 psi as the bloke who I mentioned earlier had. I've also taken all the stuff out of the boot. See how things go.

I've somehow got to manage to get about the place on £15 per week- for the next 4 months- which at the moment lasts about 2 days, if I'm lucky.

Any other suggestions of how to improve the mileage are warmly welcomed.

i just got 24mpg on my last tank,

60ltrs got me 325 miles....

gutted!!! :(

can the aircon really drink up that much of my fuel?

thats the only thing ive done differently from my last few tanks, where i was getting around 250miles from 35ltrs ~ 32mpg

:(

[Yonzie]

I drove 534 km on my first tank which was 53L. Matches up pretty good with the advertised 10.3km/L

I have the aircon on always, change gear at 3000rpm usually. Sometimes it gets abused a bit and sometimes I try to be eco-friendly. I've found that driving at city speed (constant speed, flat road) in 5th or 6th gear nets you a 20km/L (57mpg) consumption.

57 mpg!!!! What are you doing towing the IS from another car

2. Over-inflate the tyres- one bloke reputedly did this and got fantastic mpg, and told the Lexus garage not to touch the tyres because he gets such good mpg as a result. I'm guessing you wear your tread out quicker though.

This is also likely to reduce grip, so be aware.

[lee_iceman]

Last tank was 60.46 litres. Managed 290 miles out of it :( so around 21mpg, most of it contry lane driving and driving with a full load.

Usually change gear around 3000rpm, unless I'm having a bit of fun then change around 5500 :)

This is the calculator I use

That is not good fuel economy if your car is standard :o
