If you look up your machine ’s fuel saving on theEnvironmental Protection Agency ’s Web site , you’re able to ascertain the official rating for your auto – as long as it was built after 1984 . But the prescribed rating belike is n’t your very own literal fuel saving . TheEPAputs car on rolling wave in a science lab and break away them through a very specific lot of test . You , on the other hand , drive like a maniac . Do n’t deny it .
There are two ways to gauge your vehicle ’s fuel economy : air mile per gallon ( mpg ) , which is in all probability the most common way to phrase it in the skillful ol' US of A , and gallons per 100 miles ( g/100 m ) which is all newfangled and Euro - style – sort of like the Daft Punk of fuel economy . It ’s also a much easier means to liken fuel consumption between two dissimilar vehicles . Here ’s how tocalculateeither .
Miles per Gallon :
Bam ! You got your statute mile per gal right there , mathematics ninjas . And now that you know how to calculate your cable car ’s specific mpg , you’re able to overturn that line and happen your gallon per hundred miles .
Gallons per 100 Miles :
Quick Tip : The EPA is adopting the gallon per 100 geographical mile model , so you ’re going to see this issue list near the stat mi per gallon rating on every window spine if you ’re machine shopping in the near time to come .
Lots More Information
I realize in writing this that I had never calculated my gondola ’s fuel ingestion . I have it off that I fill up every 250 miles or so , and that at my last filling - up , I purchased 12.38 gallons of gasoline ( the receipt was still stuffed in the console table cubbyhole ) . So that ’s 250 nautical mile divided by 12.38 gallon , for a kind of sad 20.19 mpg average . According to the EPA , the combine score for my car was supposed to be 21 mpg , so I ’m a small low . They also have the average exploiter ’s mpg , which is 26.9 mpg . I ’m right smart below that , too , which says a muckle about my drive – maybe .
They did n’t value gallon per 100 miles in 2005 , so I ’m on my own here . But if I take the reciprocal of my mpg ( 1 divided by 20.19 ) , I get .049 . Multiply that number by 100 , and that ’s 4.9 gallon per one hundred miles ( g/100 m ) , which again is n’t very great . All in good order , hunky-dory . Slower starts from ruddy lights for me from now on .
