So yeah, I just wanted to point out to anyone reading this forum that your mileage will depend on where you live (in addition to a variety of other things of course). When I drive to the cottage (mostly highway, although the highways I drive on our probably considered just as busy as an average city road to some here!) I can get 7 L/100 (33.6 mpg). I'm sure if I lived in some tiny town I could easily double my mileage. Without knowing the exact location and as well as the conditions that people are driving in, the numbers you find posted here are nothing more than a range of something you could hope to achieve given the same conditions of some random person on the internet.
Not sure what you mean by "based on an online calculator", but in these sorts of situations where you suspect a car's fuel mileage is dropping, the first thing you should be doing is keeping a good log of gas usage and mileage over a period of time and doing the calcs by hand. Ignore the gas gauge - it may simply have changed calibration.Last 2 weeks, my Elantra Touring 2012 started having major fuel mileage issues.
Then..... it dropped to 22 or 23 mpg based on an online calculator. This weekend, I drove open road with no traffic (45-60 mph) before 7 am to avoid hitting breaks. I only got 95 miles before I blew through a quarter tank.
Have your rear brakes checked. They could be stuck. It's happened to a lot of members. Are you noticing excessive brake dust on your rear wheels?I bought my 13' E last October with 15k on. Now it's up to 34k and even though I haven't changed my driving style and am driving more cautiously as I started noticing my poor mileage (I actually drive more on the highway now--80% highway driving and 20% local), my MPG steadily dropped from 38 to now 33-35. I know this may not sound bad, but my range seems rather ridiculously bad.
When I fill my gas in, I completely fill it in, and my range comes up as 400 miles. By the time I need to refill (around 3 bars left), I've only driven about 230-260 miles. I live in a cold climate and all, but is this normal? I don't even crank up my heat!! I used to be able to get at least 320 miles only couple months ago. I have been noticing some rear brake noise, which I suspect could be a problem. I also had my engine light come up in Aug, which the dealer thought was a faulty alarm and cleared, and hasn't come up since. Anyone experienced a similar situation?
FOLLOW UP:Last 2 weeks, my Elantra Touring 2012 started having major fuel mileage issues. Used to get 29 mpg mixed driving. I'm a telework employee and drive during non rush hour for personal reasons. Out before 6 am and home before 6:30 am. Car sits all day.
Sometimes I could get 130 miles the first quarter tank of gas. Only had to fill my car up twice a month. Then..... it dropped to 22 or 23 mpg based on an online calculator. This weekend, I drove open road with no traffic (45-60 mph) before 7 am to avoid hitting breaks. I only got 95 miles before I blew through a quarter tank.
Somethings wrong and I don't play around with my cars. Going into dealer tomorrow morning.
My car is 4.5 years old, 43400 miles. Well maintained (oil change, tire rotations, emissions testing, etc). Only driver and it sits in my drive most times.
I'll see what they say. But I don't want this turning into a costly repair, so if it's $90 tomorrow better than $400 in 2 months. I'll post the mechanics diagnosis on here.
What I told mechanic in notes for my appointment: no pulling, tires at 31 psi resting, not running hot, idles well, no brake noise, no dashboard lights, and dates of my last oil change-tire rotation-fuel induction service-emission test-cabin air filter.
I don't need another fuel injection service as I've been told I had 2 done: one at 22,000 and another at 30,000. Mechanic said don't worry about it until 60,000. He looked over my services and said my car is up to date on everything. The following was done and recommended until my 45,000 service which will be oil/filter and multi point inspection.
1) he put in an entire bottle of Hyundai brand fuel additive (looked like a Techron bottle)
2) told me to stop using low end - no name brand regular gas stations (which I do)
3) told me to drive current tank to empty and fill up with high octane gas from BP or Exxon
4) after emptying tank a second time, fill up with mid range gas from BP or Exxon
5) keep using mid range gas from BP or Exxon until 45,000 service
6) told me to track fuel mileage with online site like fuelly to discuss at 45,000 service
How much did I pay: $12
note: I'm a woman and I just don't want to worry about my car so for piece of mind, I will pay money to have a trained person fiddle with my car and give me advice. My father's advice to me was always. "don't buy a car you can't keep on the road". I can afford to drop in on my mechanic if I'm worried and I do.
I'm happy with my morning service at the dealer :laugh:
Although the MPG readout on the dash, has never been very accurate, it was Way off on my last fillup. The dash read, 40.8 actual was 35.2!?!?
