F8L Posted January 17, 2013 Report Share Posted January 17, 2013 http://www.caranddriver.com/columns/mileage-no-its-your-gallonage-that-really-counts There's a sneaky illusion in mpg numbers. Consider: If your pickup rated at 10 mpg gets only 9, you shrug and say it's off only 1 mpg. But if you drive a hybrid labeled 50 mpg and it drops the same 10 percent to 45, you complain of lousy mileage. The illusion tricks you once again when you think of mpg instead of the fuel you actually burn. Hybrids are chosen by people who think saving gas is right up there on the list of American virtues with motherhood and voting. But when the hybrid gets 45 mpg instead of the expected 50, a 100-mile trip consumes less than a quarter of a gallon more than expected. Compare that with the pickup that gets 9 mpg instead of 10; its 100-mile trip burns 1.1 extra gallons. The loss of 10 percent on the pickup's mileage actually burns five times the extra gas used by the 10-percent shortfall in the hybrid. If, instead of our customary miles per gallon, we rated fuel economy in gallons consumed over 100 miles of travel, as the Canadians and Europeans do (well, they calculate liters per 100 kilometers), "we wouldn't be having this discussion," German says. If we used a gallonage standard instead of a mileage standard, everyone could see that 11.111 gallons per 100 miles of the pickup is a big deal compared with the 2.222 gallons of the hybrid.For those of you who are bummed out by lower than expected fuel economy, just run the numbers and see if it helps you feel better. :) valkraider and pomtrey 2 Quote Link to comment Share on other sites More sharing options...

Jus-A-CMax Posted January 17, 2013 Report Share Posted January 17, 2013 Some sensibility, thanks for the post F8I. Still, $450 is a lot of beers ;) Adair 1 Quote Link to comment Share on other sites More sharing options...
F8L Posted January 18, 2013 Author Report Share Posted January 18, 2013 Some sensibility, thanks for the post F8I. Still, $450 is a lot of beers ;)it was all making sense until you put it in terms of beer instead of money. Now it feels like a real loss. :( Adair, Jus-A-CMax and zhackwyatt 3 Quote Link to comment Share on other sites More sharing options...

JulieB Posted January 18, 2013 Report Share Posted January 18, 2013 Hey, it all depends on what kind of beer you're buying! ;-) Quote Link to comment Share on other sites More sharing options...
PWBarrett Posted January 18, 2013 Report Share Posted January 18, 2013 Granted we don't put as many miles/yr on ours as some do, but...Going from our old car to the C-Max, if it only gets 40MPG, saves us $75/mo.If it got 47MPG, it would save us an extra $9/mo. No Big Deal! But then $9 would buy two more Guinnesses... Jus-A-CMax 1 Quote Link to comment Share on other sites More sharing options...

Tree63 Posted January 18, 2013 Report Share Posted January 18, 2013 (edited) Gallonage is important. I'm also keeping an eye on what percentage of my trips is on EV miles. Now I have a car where my driving habits can continue to reduce the amount of gas-powered miles. (Granted it all ties together in the end.) And I like to think I'm entitled to a gallon of beer/wine at the end of the day for every gallon of gas saved along the way.

Jus-A-CMax Posted January 18, 2013 Report Share Posted January 18, 2013 That's the spirit everyone - I think we've just found a common currency of mileage we all can understand, forget monetary, it's the beer currency. Saved a gallon, thats a Flat Tire drink there.Oh that's a whole six pack Sams Adams in savings. Woohoo! Ok, ok, include winers and mixers too.... ;) Adair and F8L 2 Quote Link to comment Share on other sites More sharing options...

Never really applied gallons saved but I like the savings. Quote Link to comment Share on other sites More sharing options...
