Good morning to all. Are there several different methods for calcuating fuel economy? Basically, I'm curious as to how you all come up with your numbers. I've read that the DIC is often incorrect. Thanks.

: Methods for calculating fuel economy Mike_in_Wisc 06-23-2005, 09:24 AM My LS is female, doesn't have a DIC (stole that line from another post on here) Just fill until can see fuel in fill tube. Usually another gallon after the automatic 'click' shutoff. Divide miles driven by gallons bought. Pretty much gives a common point of reference every fillup. marcdeluca 06-23-2005, 10:23 AM That is way too simple. I prefer to read the number of microliters of fuel injected per injection on my scanner, multiply that by the injections per mile, then convert that to miles per gallon.):h (http://dieselplace.com/forum/misc.php?do=getsmilies&wysiwyg=1&f=40#) aka108 06-23-2005, 11:50 AM Found the DIC on my unit to be about one half mile per gallon more than hand calculated. Hand calculation assumes the fuel dispensing pumps are 100% accurate. Sure there are discrepancies with either method.

TxChristopher 06-23-2005, 06:36 PM The best thing I have found for using the mileage indicator on the DIC is to give me a decent idea of what my mileage will be, and if I increase or decrease my speed and settle it on cruise I can see the benefit or penalty via the DIC.:) Like the others, I have found my DIC to be off somewhat. Seems my DIC tends to exaggerate upwards. The wife says this is a common trait among DIC owners. :eek: Go figure. .
