Car Forum / Hyundai Cars / September 2007Elantra Scangauge city mileage update
Well, the Scangauge I bought is working great, and I thought I'd share the new tank of gas mileage with the group. In -pure- city driving, and we're talking not any free speed length of more than a quarter mile, ninety percent on stop and go with lights and stopsigns every two or three blocks. But decent slow driving. At this point with close to half a tank used, 22.5 mpg. And still very slowly dropping. Frowny face. Normally it's a mixture of freeway and town, which puts it around 26 to 27, but this stint of stop and go really takes it's toll. The good part is that I know it will get around 40 on the road, which makes it a little better. But still impressively low I think. > Well, the Scangauge I bought is working great, and I thought I'd share the > new tank of gas mileage with the group.

Shutting off your engine at lights will help significantly. > Normally it's a mixture of freeway and town, which puts it around 26 to 27, > but this stint of stop and go really takes it's toll.

Something in the range of 36, perhaps 37 is more like it, provided that you drive reasonably. > But still impressively low I think.

Well, the one true trip I took that needed a fill-up off the interstate was right at 40 mpg. And the Scangauge in instant mileage mode hovers right at that rate on level ground (plenty where I live) at 65 - 70. Any faster and it heads down into high 30 figures you note. So it seems to be fairly accurate so far, albeit based on that one trip. >> But still impressively low I think. > > What's impressive about low mileage? I admit my verbiage incompetence. -Depressingly- low enough to make me look at the Prius web pages in envy. And halfway seriousness. Double city mileage is serious stuff (to me). Long term payoff or not. > Well, the one true trip I took that needed a fill-up off the interstate was > right at 40 mpg.

If you're not filling up at the same pump or at least averaging the mileage over several fill-ups, you may get abnormal readings, since the shut-off setting on pumps varies considerably. Additionally, if a trip is one way, it can be affected by wind and terrain. 40 mpg is beyond what the Elantra is capable of averaging at normal highway speeds, though people who drive long distances at ~50 mph have seen that kind of mileage. I've started to keep track of my milage simply calculating it based on the amount of gas and distance travelled since the last fill up. I'm driving a 2002 2.0l Elantra. I do mostly highway driving around 100-120km/h which is about 60-70mph and get 39MPG or 8.6 l/100km for those north of the boarder like me ;-) Those figures are based on 6 fillups mostly from about 1/4 - 1/2 empty having travelled 2218km. The only thing i've really gained from this is that i drive a heck of a lot more than i thought. However, i am getting about what i expected from the data i've seen on my vehicle. -- Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai/ More information at http://www.talkaboutautos.com/faq.html >I've started to keep track of my milage simply calculating it based on the >amount of gas and distance travelled since the last fill up.

LoL If it isn't then the online calc i'm using doesn't work haha -- Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai/ More information at http://www.talkaboutautos.com/faq.html >LoL If it isn't then the online calc i'm using doesn't work haha Try the one at http://www.euronet.nl/users/grantm/frans/fuel.html If you want to do it yourself, here are some conversions for various parts of the process. I found these at http://en.18dao.net/Measure_Conversion/fuelconsumption ------------------ To change into miles per gallon (UK) miles per gallon (US) multiply by 0.833 miles per gallon (UK) miles per litre multiply by 0.22 miles per litre miles per gallon (UK) multiply by 4.546 miles per gallon (UK) kilometres per litre multiply by 0.354 miles per gallon (US) miles per gallon (UK) multiply by 1.2 miles per gallon (US) miles per litre multiply by 0.2642 miles per litre miles per gallon (US) multiply by 3.785 miles per gallon (US) kilometres per litre multiply by 0.4251 X miles per gallon gallons per 100 miles: divide 100 by X (both gallons must of the same type) X miles per gallon (UK) litres per 100 km: divide 282.5 by X X miles per gallon (US) litres per 100 km: divide 235.2 by X X km per litre litres per 100 km: divide 100 by X X miles per litre litres per 100 km: divide 62.14 by X ----------------- I wrote up a little spreadsheet using these conversions. I'd email it, but it's so simple, I'll just write it this way: Cell Contents ---- -------------------------------- A1 MPG -> litres/100km C1 litres/100km (US Gal) E1 litres/100km (Imp Gal) A2 C2 =IF(A2;100/(A2*0.4251);0) E2 =IF(A2;100/(A2*0.354);0) A4 Litres/100km -> MPG C4 MPG (US) E4 MPG (UK) A5 C5 =IF(A5;100/A5*0.6213712*3.785;0) E5 =IF(A5;100/A5*0.6213712*4.546;0) ----------------------------------------- A1, C1, D1, A4, C4, E4 are all strings Enter MPG in A2 Enter litres/100km into A5 Yep looks like the online calc i was using sucked.. Over 3384km of driving during the past month i'm getting 28.5 us mpg and 8.32 l/100km not as low as it could be but driving at 100-120km/h doesn't help i'm sure. -- Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai/ More information at http://www.talkaboutautos.com/faq.html > Yep looks like the online calc i was using sucked.. > [quoted text clipped - 5 lines] > Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai/ > More information at http://www.talkaboutautos.com/faq.html At speeds in the 100-110 KPH range on the highway, you should be able to get over 35 mpg, if your car has a manual transmission. |
