Fuel economy thread
Everytime I post in an automotive forum, it seems like there's a fuel economy thread. Thought I'd start one here.
Just post your vehicle, mods (if any), and driving style along with your fuel economy. If you use a the imperial system and want to convert to metric, just type (xx)mpg in l/100km into Google and it'll do the math for you. I'll start.
'99 Dodge 1500 conversion van, 360ci (5.9l) OHV Magnum V8, 4-speed auto, 3.55:1 gears. Rolling hills, conservative driving style, lots of cruise control, little a/c use, apx. 75% in-town/25% highway use.
13.8mpg / 17l/100km average, best was 15.69mpg or 15l/100km (which I can improve upon)
-
'04 Dodge Dakota Sport Plus club cab, 4.7L SOHC Magnum V8, 5-speed/multi speed auto(3rd gear, 4th gear, and 5th gear each have an overdrive),3.92 gears. Flowmaster exhaust. Hills, not a lot of flat land, agressive starts and overdrive is usually off. Mostly city driving, some highway.
Avg about 12mpg. Highway gets up to 22.1mpg. Towing about 6mpg.

92 Holden Commodore. 3.8lt V6 (High-flo cat with sports system, S/C Cold Air Intake) 4 speed Auto. Factory stock diff 3.08. Run 98 octane only. No cruise control.
Driving style can be on the fast accelerating at times but i'm a smart driver so i also know how too save fuel at times when needed. 99% Local driving very rare too hit the highways.
Tank size is anyone's guess as it's not standard and has a large dent, But takes on 66 litres average.
14.6l/100km. 19.2/mpg. It could and should run under 10l/100km 28/mpg 100% on the highway.

mini cooper s with no mods (a rarity, but i like my warranty)
with my heavy right foot, a pretty good mix between city and highway, and the addition of up to about 15% ethanol to our gas here in VA, i am getting about 26 mpg.
before the ethanol, i was making just below 28mpg, but the ethanol makes it slower, rougher running, poorer mileage, and makes the tailpipe black like an old diesel's.

Yeah, the ethanol isn't going that well in cars that aren't made for it. I've heard similar complaints all over the place about it.Performance builders familiar with building alcohol drag engines are looking pretty hard at it though since it has characteristics similar to alcohol (high resistance to detonation, but less heat energy than gasoline).
-
Clio 1.6 16V
7-8L/100km on average
6.2l/100km or so on long highway trips
8.4l/100km when I drive agressively, i'm averageing 8.3 at the moment according to the on board computer.
I once managed to average 5.8l/100km which is impossible according to Renault. I'm really happy with the fuel economy of this little car. It's next to impossible to average more than 8.5 litres.

Alfa 166 sedan, 2.0 TS 16v, 150 Hp - I manage just a regular 1 : 9,5 kms - on the highway to France just 1 : 11 kms; excactly like Alfa Romeo states in their brochure.

theoretically it would work great, it boosts the octane quickly, easily, without as much refining of the gas, but the O2 sensors, and fuel injection systems need to be re-callibrated. what ends up happening is it doesn't see the right numbers coming out of the tail pipe, so it dumps more gas in, and then you get poor mileage.

97 Golf 2.0 8v, drilled airbox with K&N, no muffler (huge loss of backpressure), close ratio 16v trans 3.67 final drive.
Beat on at all times.
Averaged 28-29mpg driving to school every day.

1998 Chevrolet Blazer LT 4x4 with the 4.3 liter vortec V6. On average both city and highway driving its around 18mpg. I still have the window papers from the dealership when it was new and it says 16 city and 21 highway, so yeah its still pretty close.

Excuse me, I forgot you car is driven at 1milMPH because its the special AXB edition.

Oh no henk! No speeding involved! Answer to your question, see the 'My '05 Audi A6' thread in 'Users Rides' :(

[QUOTE=henk4]try excessive speeding:D[/QUOTE]
No, that's having a car taken from you. "Lose" makes it sound as though he has misplaced it.
And he did...
You can't find the car, eh? This is why I have friends who don't drink...

You'd better pray to God you don't 'lose' either of your next possible cars, because I will steal whatever it is. Do you hear me? I [b]will[/b] find it and take it for my own!
Oh yeah, anyone want to buy an '05 reg Audi A6? It's quite nice. Found it the other night. £10 and it's yours.

only recently inherited mums car, when I find some time, some photos and an egggnog to follow, but last three tanks have given following mpgs
Nissan Micra 1.3 GX
37.26 mpg
37.98 mpg
38.16 mpg
and its not sedentary driving either, plenty of aggressive acceleration thrown in, so not bad!! main tip i learnt from last fulltank, dont go crazy with the throttle when engine is cold - once its warmed up, which takes all of 3 mins, then by all means go nuts!!!
-
You thrash a Micra? You hardman :D

well my '98 rover 414i, thats the 16v twin cam btw (proud) has a faulty fuel needle meaning that it goes form half a tank to empty so i a.) can't work out the mileage and b.) haven't got the balls to see how low it'll go, that and i'm really lazy. but doing 90mph down the M5 on the way back from the girlfriend's in Newport does seem to drink more than on the way up. don't know why?!? I only have a 2 mile drive to work (again with the lazyness) but i do a lot of motorway miles seeing my girl so i will work it out sometime soon.

you don't need the fuel gauge to establish your mileage. Just write down when you refueled and calculate the number of miles driven at your next fuel stop.
