Alternate Route

Turn off the nav system, crumple up that MapQuest printout, and let's find out where the next random turn may take us!

Aug 10, 2008 - Running On Empty

As if I needed any more evidence, allow me to present my mileage figures on my return trip from vacation where I was forced to fill up with a 10% ethanol blend.

On the trip down from State College, PA to Williamsburg, VA my mileage was 32.7 mpg using "unblended" fuel. That was a little lower than I normally get on the highway no doubt due to the full load of 4 adult sized passengers plus luggage, but still not too bad. I even got 32.1 running around the WIlliamsburg area with no trip being longer than 13 miles.

On the return trip we had to stop for fuel just north of Richmond and had no choice but E10. Same roads, same highway cruising speeds, same load. Filled up when we got back home with 9.8 gallons and had covered 296 miles. That's 30.2 mpg or a 7.6% decrease in mileage. And I paid exactly the same price for the blend as I did for regular unleaded.

Now I know there are those of you out there who are true believers who say that there's no way this is happening because of ethanol and you couldn't be more wrong. Time to put down the Kool-Aid folks.

i've verified the same results more times than I can count: oxygenated fuel costs substantial mpg both wtih MTBE as the oxygenate as well as ethanol, starting in about 1993 with RFG1 in California on honda civics, and with many NH<->FL drives with both XC90 2.5T and GTO 6.0. in my 1990s tests with honda civics and my 100 mile daily commute, the mtbe oxygenated fuel gave noticeably better mpg than the ethanol-oxygenated. my 92 civic EX mpg went from over 40 mpg to 28 after RFG1 was introduced! current ECMs adapt to the diluted gasoline better than did the 1992 vintage ECM, i'm guessing.
