I drove down ocean parkway in long island which is a fully leveled 14 mile strip with some light dips and bumps in the road. with cruse control on a steady 55mph i was getting an average MPG (Which was reset just before starting the 1st mile) of 33.1 MPG. I assumed there could have been a slight decline going from west to east on the parkway, so i did the same thing coming back and reset the AVG MPG before the 1st mile, coming home i Averaged @ 34 - 34.1 MPG... i had about 1/3rd tank of gas the entire trip.

Ive read that people who have their new Patriots have to experience a break in period before they start seeing decent MPG. My ride has less than 200 miles on it and im already seeing fantastic fuel economy.

My question is how accurate do you think the built in Vehicle Information Center is as far as the Avg Mpg? you guys think my numbers are accurate? these numbers beat the EPA stated fuel economy for our Patriots so i find it hard to believe.

I think it's too soon and too short of a distance driven to assume this will be your AVG. I know EVIC isn't spot on when it comes to AVG MPG numbers. The best way to check is to use your pencil and paper or Fuelly and take your total number of miles driven divided by total of number of gallons used. The reason you got those numbers is 55 MPH set with the CC on the flat surface probably at sea level. I've never broken 30 MPG myself but I had bigger tires, lift and the basket most of the time. My highest MPG I ever got was 28. Track a few tanks. That will give you a more clear picture of your MPG.

agree with tjn,
too limited to get accurate reading,
would check by the tank full,
reset tripometer at fill up,
next fill up divide miles driven by gallons used,
at first may want a calculator handy,
after a while you get used to the numbers and can estimate in your head

i really wished it would show the instant MPG or real time MPG. thats what i was trying to figure out, not necessarily my average MPG city and highway from a full tank to an empty tank. for future trips i was trying to figure out what the most efficient speed to travel at would be.

My Mitsubishi Lancer got the highest MPG when driving between 60-65mph. any increase or decrease in speed between these figures would decrease fuel economy.

Im getting a wireless OBDII Sensor to work with the Torque App so i can view my Real Time MPG along with a few other cool features.

What does flat surface at sea level have to do with MPG compared to flat surface above sea level? If the Evic is Semi accurate and i reset the AVG MPG while driving 55mph in CC for the 14 miles of flat leveled surface, and it reads an average of 34 MPG just before the end of the flat leveled surface, wouldn't that mean i averaged 34 MPG on that ride?

Also i want to add that while driving at 55mph in cruise control, and then resetting the avg MPG, the Avg Mpg started at like 45mpg and moved fairly quickly down to 35 than 34 than 33.9 than 34 than 34.1 etc..

I made a 10 hour trip from houghton to traverse city and averaged 28MPG at trying to use cruise at 55mph on the way there and 26 MPG at 62mph on the way back(confirmed with tank calculation and OBDII). I've also made an offroading trip up to copper harbor and back and managed 30MPG including the offroading parts(measured using OBDII). I don't know if the temperature was just right or the hills but that's the highest I had ever gotten.

That should be almost point on to what its supposed to be. im guessing slightly cooler weather may improve MPG as oppose to scorching hot? the 14 mile strip that i drove was completely leveled out. if you search up ocean parkway long island NY in google maps its a long strip of highway minimal cars going along the ocean. i stayed @ 55 the entire time even with everyone riding my bumper. ill have to take a photo or video sometime of the trip and the MPG on the evic.

I was able to get 24 mpg 80% city driving with premium gas this last fill up. The car only has 1,800 miles on it so I hope it improves more. I'm gonna try regular this time.

I have only filled up Regular, isn't that what we are supposed to use? i wonder if premium vs regular has significant impact on fuel economy. i cant imagine the MPG difference would justify the price increase though.

I know the FD2's are supposed to use premium when offroading and that the VVT is supposed to adjust more drastically for more torque or something...FD1 here so I haven't looked into it that much.

air density at various levels would affect performance/mpgs
but being on LI dont think you have to worry about that.
affects more so those living in mtn regions,

So going back to the original question,

does that 34 mpg seem accurate with all the variables i listed? Was i in fact getting 31-34mpg along that 14 mile strip or is there something wrong with my EVIC?

For those who have an external ecometer &/or an OBDII connector with app to show instant MPG, do you find that the factory EVIC MPG is accurate enough compared to what the Ecometer/OBDII reads out?

As the others have stated, you simply can not get an accurate tally on a 14 mile trip. And 34 mpg sounds extremely high. Mine is between 18-26 depending on the conditions and the time of year. The only accurate way is to do what others have said. Fill your tank, reset the odometer, and use up close to the whole tank. Refill to full. Take the total miles driven and divide by the number of gallons used. You simply cannot go by some short little trip or any instant MPG devices. They are nothing more than gadgets.

Ehhhh. your all probably right but it was a nice thought. i guess i will have to wait for the OBDII module to arrive so i can track real time.

Taking the OBDII Module Vs an Ecometer. which in all of your opinions would be more accurate in showing real time MPG?

Thanks everyone for the input.

both should be similar as both get their info off the cars cpu,

Go OBDII, cheaper and the apps can update(to be more accurate and functional) and you can diagnose problems. I have diagnosed many peoples problems by plugging in and checking on my phone.

When I got my first one it was a cloned one($8), it worked but I had to pair it every time I started the app so I got a new one like this. It works awesome. It was $20 when I bought it so I don't know if the one I linked you is a clone or not but it's worth every penny either way. Cloned ones have a MAC address like: 11:22:33:44:AA:BB

I just did a +250 mile trip from Central New York to Central Pennsylvania and back with my new 2014 Pat Lat FDII. I was pleasantly surprised to have averaged 25mpg both ways, speed limit driving, four and two lane highways, big hills little hills, stop and go through small towns, etc. I believe it may have gotten even better were it straight highway on the tank. City is averaging 17-19 so far this end of winter, but hoping for maybe +20 on non-winter fuel?

Maybe its just that great northern air! I just drove from Marquette to Calumet and got 29 mpg!
