Stop the $%^&#$ $%$#^&% press! A lot of you must not know how to get mpg out of a civic that is not a hybrid! I drive a 2005 manual all gas civic and get 43+ mpg on the highway and 35+ mpg in the city and I do check it correctly. I consider my self the king at milking mpg from a civic. I am moving toward 44 mpg on the highway and I do not drive a HX or a VX. My car was initially marked 38 on the highway. Ask me how to do it and I will advise. Sometimes adjustments you make may not become cost effective for many many miles but at the same time you want to deny those %$#$^%& anymore oil money. |

Replying to: rick119 (Jul 08, 2008 1:39 am)  This is done in arguably one of the top 5 WORST commutes/roads in the country. To give a USA perspective worse examples would be: 1.commuting to D/T Manhattan 2. commuting to D/T San Francisco over the Bay Bridge (sister bridge is the Golden Gate Bridge) 3. commuting to D/T Boston 4. commuting to D/T Chicago (don't want to leave out any other truly bad commutes- but thems the breaks)  (I have done all of the above and more but obviously at different time frames) It would be interesting to see what changes to the mpg would be if we started hypermiling (NOT doing it, but an interesting projection nonetheless) Our 54 miles R/T commute SEEMS to fall into the optimization. 1. One hour minimum operation (anything under this is less than optimal) , 27 miles each way  45 min to 1.5 hours. What happens is all systems come up to specified operating ranges temperatures and min times. 2. best miles are highway miles, so 80/20 to 90/10% 3. I know for example we lose a min of 1 mpg having an auto vs 5 speed manual (EPA rated difference between auto/manual) To be real clear I SWAG 39-43 mpg if we used a manual. In (apples to oranges) comparison we get 48-52 same commute using a 5 speed VW TDI Jetta. My take is while the Jetta is NOT optimized for this same commute, it does take it in stride and yields the stated numbers.

I have been driving my civic for 1 year and religiously track my mileage. I recently purchased a scanguageII to see my fuel consumption in real time. Pretty cool device if you've got "OGMD" (Obsessive Gas Mileage Disorder). I recently took a long trip that I decided to hypermile on. I didn't do any of the dangerous stuff, just driving very conservative (55mph), and coasting occassionally down long steep grades. My scanguage said I got 50 MPG, over a 596 mile drive. It also said I had 1.2 gallons left in my tank. When I filled it I put 11.675 gallaons in. The calculation would be 51.04 MPG. I too believe there is variation from pump to pump and even the outside temperature can influence. I've been using the scanguageII for about 2 months and it is very reliable once you calibrate it. After filling up I needed some speed so set the cruise control for 70 for the 220 miles of my remaining drive. I got 42 MPG during this time according to the scanguageII. Pretty big difference. You can find more info out about scanguageII here. www.scanguage.com

Replying to: mikpaq (Jul 12, 2008 11:00 am) Indeed a scan gauge and/or on board computers can take some of the mystery out of what are the most fuel efficient parts of the curve, given any and all conditions. YOU of course can/do/need make the decision for literally every second to every hour of operation. Of course it helps to have a good dose of (OCB's) obsessive complusive behaviors in ones back ground. There has never been any doubt in my mind the Civic is "CAPABLE" of getting much better fuel mileage.

Replying to: gqllc (Jul 14, 2008 10:57 am) I run the wire to the ScanGaugeII and put it in the center of the dash in the pocket next to the 12V/AUX jacks (I have an EX, your LX may vary). Fits nice, just sits there with no tape or anything, wire's completely hidden. I just glance down at it every now and then. It's small, so I'm sure others have found more creative places to put it. ...kl... |

Hi I have a 99 civic lx with a manual transmission. My parents have owned it since new and now that i bought it off of them as my college beater car i figured that i would see what kind of mpg it was getting. I didn't think that it would be as high as it used to be since it now has 190k miles, but after taking a 360 mile trip i only used 8.254 gallons so..... i got an amazing 43.6 mpg! I was pretty surprised that it was still getting such good fuel economy for being so old. The trip was mostly interstate driving between 70 and 80 mph and no a/c because that no longer works, lol.

You guys want mpg out of your civic? First you need to know how to properly check it, none of this "I get so many miles out of a tank" My manual sticker said 38 highway. I get 43 plus and If I make a couple more adjustments I could get 45 mpg. E-mail me at stellars2000 bellsouth.net and I can advise.
