    Any car, any brand, will not perform it's best until the engine is fully broken in. 1800 miles is not enough. Just breathe deep and wait until around 2500 miles. :)

    During the break in period, I think it is good to get some highway miles on your engine. Also, if you have a heavy foot, or drive alot in heavy traffic, mileage will drop rapidly and cold weather is also a culpret. I'm still breaking in my Tucson as well. I changed the oil at 2000 and will again at 5000, then I'll switch to synthetic and follow the 7000 mile change interval. I'm told you can pick up a 1/2 mpg improvement in addition to reducing engine wear. Never run synthetic or blend until after the engine is broken in or the rings will not seat properly and you may never get good mileage.
  • i also have a 2007 v6 awd tucson, 15mpg is standard if you do all city driving and live in a cold climate. I have 12,500miles on my tucson now so i'm past the break-in period. Winter and city driving kills the mileage on this vehicle.

    The best i've ever done in the summer is 23.5mpg when i did all highway driving on a tank. In order to get 30mpg you would have to be driving 60 miles/hour on a flat road in 68 degree weather and never fluctuate your speed and it might be possible in the v6, not sure about the 4.

    I've tracked the mileage on every tank of gas since i bought the vehicle 1 year ago. It did improve slightly after the first oil change, but more due to the warmer weather as it got close to summer.

    I think message #86 gives some realistic insight we often forget when talking mpg for any vehicle. I think this is why the new government standards for mpg reporting by the manufacturers are tougher now. When I say I get 21.3 mpg city, it is under these conditions: 2007 FWD V6 Tucson with one person no gear, little heavy throttle, flat ground (I live near the coast), average temp in the 50s – 60s, (I live in the South), air pressure high, ( I live at sea level), 80% of my driving is commuting 7 miles to work, (3 stop signs, 4 stop lights, 50 miles/hr for about 50% of the distance, ave. speed 29 mph, trip time 15 minutes. I can get 27mpg highway with two people and no gear if I do not exceed 60 mph but go higher speeds and mpg starts falling (location and temp same as above). I reset the trip computer at each gas fill (regular) and verify mpg by calculating miles divided by gallons at the pump (usually pretty close). It is fun to compare mpg with others but there are many factors to consider before you take any of this for gospel. I'm thinking the accurate average city rating for the vehicle is 15 – 22 for the FWD V6 with one person and no gear. My window sticker said 20 city, 26 highway (17 and 23 mpg city range). The same 2008 model now says 18 city, 24 highway. Be as careful comparing mpg with other models and manufacturers.
  • Thanks so much for confirming what i thought. I really thought I was crazy and people kept telling me I HAD to be getting more mpg than I was.

    I live on the East Coast so yes to cold driving, although I do garage it overnight and never drive with a cold engine. I calculate every mile and gas stop. I really do not think it's going to get much better and with gas prices the way they are I am considering trading it in already at a loss to but something better on gas.

    Thanks again for all the imput.

    You can take the exact same car and run it through several different drivers and get different fuel economy.

    A coworker complained since day one about the fuel economy of her Elantra. It is mecanically identical to mine. I get 32-34 on the highway, she gets 25-27. Combined driving I consistently get 30, she gets 22.

    I only had to ride with her one time to understand the problem. Gas, brake, gas, brake, gas, brake ...

  • jlflemmons got it right in post 89. I live in a cold climate have at most a 5 minute commute to work, all city driving so my mileage is pretty bad.

    My buddy bought an 08 tucson fwd (see my specs in post 86), but he drives all highway to work, even though he's still in the break-in period not even 5000miles yet, he gets closer to 18-20 mpg. I saw a huge jump after break-in so he may get even better mileage this time next year.

    I agree 15 mpg is pretty bad and if i had known thats what i would be looking at for mileage for 6 months of the year i would have bought something different. I've also had my fair share of problems with a 1 year old car which doesn't help.
  • I've got 11,500 miles on my loaded '06 Limited V6. I drive in urban traffic conditions 22 miles one-way to work and some limited highway weekend miles. My avg is now 19.8. Sure, I could be getting in the high 20's or even 30's BUT with a MUCH lighter vehicle that wouldn't have all the features and space of the Tucson and I really wanted 4WD. My vehicle weighs about 3,500 pounds and there's just NO WAY you can pull that much weight and do better mpg-wise.
    As far as the above posting about re-routing the cold-air intake, sounds good but you're really screwing with the computer, messing up your emissions and will probably burn your valves. I'd stick with stock and not risk voiding my warranty.

    Here is another perspective so don't trade in your Tucson yet. Let say you are getting 17mpg and drive 10,000 miles/year you will spend $1764/year on gas at $3/gallon. If you purchase a similar SUV, say the Honda CRV or Toyota RAV4 you might get 2 to 4 mpg better mileage (RAV4 is smaller, CRV has a 4 cylinder). So, let say you can get 4mpg better at 21mpg and 10,000 miles/year you will spend $1428/year on gas for a savings of $336/year. The RAV4 or CRV will cost you at least $3000 or more to purchase over the Tucson so it will take 9 years before you break even on the gas savings. If you put that $3000 in a simple investment that earned 8% a year in interrest, the earnings over 9 years would pay for the gas milage differance of 4 mpg and you would still have the $3000 left!

    Toyota is a good car, but in my mind, inferior design because you have a stupid tire hanging off the back, side opening hatch and it is smaller. I can't say anything bad about the Honda CRV except I think it is a bit ugly and they think a lot of it and charge accordingly. It is also only a 4 cylinder. Both these autos have half the warrantee and you can't beat the fold flat seats in the Tucson or the nice storage under the rear compartment lid, or the full size spare under that, or the great mp3 player, all the features and built in options and nice up-right seating position. I think that is why many of us purchased the Tucson, good value and a very comfortable and safe vehicle.

    I can understand your concern about modifying the cars intake for better performance – my wife doesn't like it either. But, I am an engineer and I like to tinker. The safest and least disruptive modification you can do to a modern gas engine is to improve its air intake. It does not have any negative effect on the computer or emissions because the computer senses the air flow increase and adjusts the fuel/air mixer and timing accordingly. Every auto manual warns you about diminishing performance with plugged air filters, I'm simply going the other way. All the automotive performance web sites sell high performance filters and assemblies from makers like K&N. Here is a link to WIKIPEDIA that tells you all about hood scoops and why they improve performance:
  • I really hope you will post your results if you modify your vehicle. We may all want instructions!

    I am getting 23-24 mpg on mostly highway miles. At the price of gas, we can all use improved performance.
  • I have a 2007 Tuscon with the 4 cylinder engine. My commute to work is about 3.5 miles. When I just go to work and do not do any highway driving, I get 17-19 mpg. I had a 97 crv that got 23-25 for the same distance, I have take a 125 mile trip and I got 21.7 on the hwy with the Tuscon. I am heading to Maryland next week and will drive about 700 miles. I will repost my results. Other than the gas mileage, I really do like this car. :shades:
  • I purchased a new 07 Tucson in June 07. I normally avg about 335 miles to a tank full of gas. My avg mpg on the highway has topped at about 22 mpg on the highway. I have been so impressed with the vehicle (the way it drives, the comfort) but have seriously considered trading or selling it due to the poor gas mileage. I have the 4 cylinder model and it is depressing. This thing reminds me of huge Olds I drove back in the late 70' never could make it past a gas station without needing a fill-up.
    LOOK very closely if its comfort you want.....if not, pass on the wont deliver the MPG unless you have deep pockets ! It LOVES gas !!
  • Well i'm in the same boat as tusconstar above, but i've had my tucson for over a year. I get worse gas mileage (v6, awd, cold climate) but i felt it was ok since the truck is really quite comfortable and nice to drive. But things have started going wrong with my 1 year old tucson and the dealership is a royal pain in the butt to deal with. So this weekend i started shopping around, unfortunately it looks like after a year of driving the vehicle has depreciated by $10,000.

    I'm looking at the 2009 toyota matrix, hopefully it will be greener pastures.

    I traded in my 2006 tucson for the mileage issue and gas prices these days. I just made a trip of over 500 miles and averaged 36 mpg on the trip and got 40.26mpg in a 285 mile leg of the trip. I really liked my tucson but I am glad I got the 2007 elantra for the mileage that im getting. :)

    Haven't calculated that for a long time. But mine (05 v6 GLS FWD) had only around 20 mpg after 5000 mileage. It sucks and won't buy any more Hyundai.

    I recently drove across Canada from Kingston Ontario to Vancouver BC in a brand new Tucson GL 4cyl auto 2wd. The vehicle was found to be very comfortable (great seats), quiet, has good driving dynamics & excellent brakes. I found 4 things that I disliked -- just-adequate power, racous engine at full throttle, slightly odd accelerator position & poor fuel economy. The vehicle load was 450 - 500 lbs including passengers & we cruised at the highest tolerable speed that policing would ignore (10 - 20 kph above the posted limit).

    We did not drive with economy as a priority, but neither did we try to beat the hell out of the car. We simply drove as circumstances required to get "there" from "here". The absolute best milage we noted was right on 25 MPG (Imp gal. --- about 21 MPG US gal), with 22 - 23 being more common & less than 20 as we ground our way through the rockies. My Chrysler 300C is better than that & my 3.2 L Chrysler Concord is a bunch better!! We didn't notice any particular improvement in performance or economy as the trip progressed over the 5000 km total, so I'm not convinced that break-in is an issue.

    There is ample cruise power at any sane speed, but passing on 2-lane roads requires planning & care. While it climbed the mountains without becoming a mobile road block (1 vehicle passed us in the Kootenay Pass), it sure worked hard at continuous full throttle in 3rd gear for many km in the passes. We were able to maintain at least 80 kph (50 mph) in all passes, except for 2 brief drops back to 70 kph at the 2 steepest points in the mountains.

    I came away from the trip with considerable respect for the beast & I am considering buying a 6 cyl Tucson to replace my Concord which is nearing the end of its economically viable life. However, with gasoline at >$1.30/L I might buy a used 300C for the same price -- it's cheaper to run than the Tucson.
  • My 2007 Hyundai Tucson, which I bought new, is only six months old. I only have 1800 miles on the car and drive mostly in town. The literature estimates 22 mpg for city driving. My car is getting a deplorable 12 mpg. Has anyone else had this experience?
  • jlflemmonsjlflemmons Posts: 2,240
    1800 miles in six months???!!!

    The problem is that your engine is probably never getting to full operating temperature, and as such is running rich. May I suggest an oil change first, because I would bet you have fuel in the oil by now. Then, at least once a week, get the thing out on the road and cruise above 50MPH for at least 30 minutes. What you are doing will not only cause the car to get miserable gas mileage, you will shorten the life of the engine by constantly running it cold and with a rich fuel mixture.

    Another point is that your engine will need at least 6000 miles on it to fully "break it in". After that point you should see your gas mileage steadily increase.

    I really don't mean to sound rude, but NO CAR will get decent mileage if only driven for short trips at in-town speeds.

    Your vehicle is still in the break inn period. You will not see normal milage until about 5000 to 10000 miles. My 2007 Tucson V6 is getting 21 to 22 mpg regularly in the city and 24mpg highway and has 9000 miles on it. Be aware that it you frequently use hard exceleration on these vehicles, the milage will plumet quickly.
