MPG - Help!

5659 Views 43 Replies 15 Participants Last post by  CWH5
Hello everyone, I barely have 275 miles on my 2010 V6 AWD Venza and I am concerned with the MPG that I am getting on the car.

I am already on my 2nd tank of gas. The 1st tank gave me an average of 13MPG. A quarter in my 2nd tank and the computer is reading an average of 10MPG :eek:

I do around 50 to 60% city and 40 to 50% Highway. What surprises me is that I am getting this type of MPG eventhough I am really being light on the pedal.

Is this normal?
Is there something I need to check?

Please help!

Thank you in advance.

wait a few weeks while your engine breaks in
That definitely should NOT be happening. There is probably a malfunction somewhere that is causing it to suck gas like it grows on trees. (running rich, faulty fuel injectors, bad spark plugs?!?) Take it to the dealer and have them inspect it. And get some fuel reimbursement :p

A new car still shouldn't be sucking that much fuel no matter how new it is. My brand new Camry has been averaging 28 MPG in 70% city/30% highway and it only has 300 miles on it. I for one wouldn't want to waste that much gas waiting for the engine to break in....and the break in period is 1000 miles! :eek:
Maybe he have been riding with the hand brake ON this whole time. :D

anyway, dealer should be able to find out why.

:facepalm:
You said "the computer is reading an average of 10MPG :eek:"... don't go solely by the computer average instead, do your own math. Fill up the tank, drive as you do, fill up the tank and calculate the average mpg yourself and see if if it yields a different result than that of the built-in computing average.

1. Try resetting your Average MPG to zero the next time you get gas, in case your reading includes some long idling at the dealer when it was being prepped.
2. Does your Current MPG reading go up to 90MPG when you are coasting? If not, take it to the dealer.
3. Is the shifter in full automatic? If you have it in sequential mode, you might be driving around in 2nd gear (or worse).
Get it checked-out at the dealer. I've averaged 20.8 since day one. That's 90% rural driving with moderate stops and starts.

Road trip this weekend. I'm curious about my highway mileage.
Even when I drove like I stole my car, my worst was around 14mpg and that's a V8.

When I fill, the mpg get reset and zeroed but quickly get up to 15mpg and above.
Breaking-in a vehicle only adds 1-2 mpg, if anything. Something is wrong.

There is no way break in will make near that much difference. I noticed MAYBE 1mpg better after breakin. I average 22.9 combined and as high as 27.4 highway, and have never gotten under 20mpg on any tank. There is NO DOUBT a problem / leak with his car.
Thank you all for your responses. I will be taking the car to the dealer tomorrow to see what they say. I hope they do find something and address it. I really was expecting much better MPG from the Venza. I'm basically getting the same MPG I was from my 2001 Sienna V6.

1> Yes, I did reset the average MPG to zero on the 2nd tank and it's reading around 12MPG now :eek:

2>Yes, the MGP reading goes up 90MPG when coasting.

3> Shifter is set to D (Full atuomatic)
Question; So when you step on the gas lightly (RPM 1.5 to 2), what does your current MPG reads?

Mine shows 3 to 6MPG.
^ that is not the correct question. When I cruise setting around 70mph, my RPM stays around 2 but that MPG moves quiet a bit and it depend on the road. MPG is like the more sensitive of RPM.

3 to 6mpg display really say that you are pressing MORE on the gas.
The only other easy thing I can think of is your tire pressure, but with your car being so new, I wouldn't expect that to be a problem.

I'm all out of ideas! Let us know what the dealer says!
Maybe you just got an odd-ball inefficient Venza that gets worse than Land Cruiser mileage. Like I said before....go see the dealer. Tell them everything you've done to make sure it's an accurate reading.
