Linky that made me thinky bout this.

So they say your car is supposed to go so far on so much gas, and you believe them kinda, or not because they're all lying trolls trying to get their hands on your hard-earned money. But ultimately you get a car and drive it around the numbers pop up on the little screen, or you do the math in your head, or you simply don't care and drive around wondering where all that extra cash has gone as your engine gets coated in goop.

So are those fuel economy ratings any good? Do you even care? Does your car do better or worse than listed? Do you think that's your fault or did someone pull a fast one on you?

How does your automobile do?
Better than estimated and it's because I'm awesome.:5 (45.5%)
Worse than estimated; but it's my fault.:1 (9.1%)
Better than estimated, company screwed up.:0 (0.0%)
Worse than estimated, they lied to me!:1 (9.1%)
Don't know, don't care, don't drive, don't nothin':2 (18.2%)
I'm nothing but a tool of the automobile industry and believe the mileage I get is almost exactly as advertized.:2 (18.2%)
Total:11


Me?

Our Rav4 is rated 24/31 MPG. We never seem to make the in-town economy we're supposed to, and spend most of the time barely breaking 20. However I've blamed the abundance of hills and what not for that mostly. The highway mileage seems low though. We averaged 35-38MPG on our last vacation which had about 2500 miles of highway driving on it, so I kind of wonder why that one wasn't listed higher. Odd stuff, as one doesn't usually expect to make the listed mileage, at least in my experience.

Worse than estimated. Probably my fault... car is a 2005 and hasn't had a tune-up, etc and until a week ago my tires were bald like Telly Savalas and one was running half flat much of the time from a plugged double puncture.

Supposedly my car gets 20 city/27 highway. In reality I get around 17 mph between long stretches of open road (~60 mph) and stints of suburbia stop & go streetlights. I should probably try to do something about that.

Fine, 15+ km/l.

Canadians... Smiley: oyvey

I'm usually pretty good, but this is one of those things I just can't translate in my head. Inch->cm, temperature, volume, etc all that stuff comes fairly easily; but changing two units at once... ugh! Was talking to the relatives about this when I was up in Edmonton, and was just glad they'd grown up using English units, at least for a time. Smiley: lol

38 MPG is 6.19 L/100km

km/l isn't a thing.

The transposition is hard because you're not just converting two units, but also swapping the relationship.

L/100km lets you very easily calculate cost for any trip based on distance.

But you can do that without writing it backwards too. Or is this a color/colour thing? Or maybe it's just my elementary math teacher's harping on me for too long.

Not as easily.

take a 600 mile trip, how many gallons is that? 600/38 = **** it.

Take a 1000 km trip, that's 10 units * 6 litres is 60 litres.

I usually see it as a shorthand for 1 liter every xx kilometers in Dutch (1 op xx). I don't pay a whole lot of attention though as I cycle pretty much everywhere anyway.

A bit over 15...

Either way the car has a thingy that says how much further until you putter out. Which, while being super awesome, doesn't agree with the woman in the passenger seat who demands we stop anytime the gauge approaches 1/4 tank. Smiley: rolleyes

Still not.

My Malibu (faux)hybrid is listed as 26/34=29. Right now my computer is reading 28.4 since I stopped driving it for work. I've gotten 33-34 on the highways before (I did upwards of 1200-1500 miles per week last summer) but these days it's mostly relegated to in-town, and it needs a tune-up and an...evap purge vent replaced.

My car does about what the sticker said - still, I believe. It's two now.

In the summer I average around 32 in the winter it drops by a good 4 mpg.

Didn't Ford just get whacked by the EPA for fudging it's MPG ratings?

Ok. But if you have a 10 gallon tank, listing it as MPG allows you to know how far you can go between gas stations. Which is important when you live somewhere where you don't bump into another country every 100 miles or so. So in your example above, I don't necessarily care how many gallons I'm going to consume, but I can easily say my cars tank can get me 380 miles, so to be safe I should be stopping and getting gas every 300, which means I'll stop twice on a 600 mile trip.

It's not like the math is terribly hard to estimate safely no matter which way you present the data. Now you want to know what's truly useless figure? My car has the usual gas gauge and range calculator thingie, but it also has a special mode in which you can view the all important super secret and much sought after "gallons/hour" calculation. Um... What? How the hell does that help me?

Short answer: It doesn't.

Not really. In the actual world, no one gives a fuck about your imaginary family that frequently makes 600 mile trips and would be mystified by measuring efficiency in gallons/10k miles, because we assume, they can't multiply by .06, and, magically somehow, they only journey places where the goddamn gas gauge would confound them with it's analog self and cause them to miss the "last gas for 400 miles" station Needles or El Cajon or wherever it is these idiots are going.

MPG is a terrible measure of fuel efficiency once vehicles become reasonably efficient. As they become very efficient it becomes even less useful. I don't think it was intentionally designed that way, I think the US just has ******, poorly thought out measurements in many areas and is resistant to change. Hence the idea that 34mpg is much worse than 40mpg when it's a marginal difference, and the idea that 12mpg is basically the same as 18 mpg when it's a huge difference. I don't really have an opinion on the "how my car does compared to the MPG rating" thing. I don't really pay attention. I assume our primary car (a 2010 Corolla) comes in around 30 for our mix of occasionally long highway trips and random 1 mile drives to the grocery store or soccer practice. Neither of us commutes via car, and we don't drive much, so it's really not that much of a concern.
