Toyota Matrix: MPG-Real World Numbers

    30-31mpg is OK if driving in cold weather and using gas that contains ethanol.

    Those 'chips' on ebay are just a 5 cent resistor in a fancy box.
    It tricks the engine computer into injecting a bit more fuel to slightly increase power (expect REDUCED mpg!).
    There's no simple way to increase both power and MPG.

    A cold air intake might increase power slightly only at full throttle.
    The stock air intake is cold air, with slightly more restriction and less noise.
    If you're trying to increase MPG you won't be spending much time with the throttle to the floor!

    To save fuel:
    keep the tires fully inflated (I run the fronts at 36psi instead of 32psi).
    get the wheel alignment checked
    don't use oil thicker than 5W-30
    check for dragging brakes - feel for a hot wheel after a highway drive with minimal brake use
    always keep the overdrive enabled.
  • Yes, it has been cold since I've had the car. Any guestimates about what could happen with warmer weather & warm weather gas?

    Hmmm...just a fancy resistor huh. The comments/feedback people have posted sure make you think it's more than that & it CERTAINLY doesn't mention it will LOWER mpg's. :(

    Sounds like the cold air intake would go unused 98% of the time with me so that purchase won't happen.

    Thanks for the other tips.
    I knew about the tire pressure & alignment suggestions but not the oil or dragging brakes. I'll have to check it out.

    Now, if only I could figure out how to collapse & store the collapsible cargo cover thingy I'd be set! :confuse: :shades:
  • My mileage drops about 4mpg in the winter, in Wash. DC.

    Some of the buyers on Ebay leave the feedback before they use the device long enough to make a meaningful test.
    The rest are placebo or just wishful thinking.
  • your car is a 2003 its not going to get as good of gas milage as a new car getting a diagnostic cost money get over it

    Has anyone who heard a clunk,pop or knocking noise when turning the steering wheel tothe left or to the right? SEE Toyota Technical Service bulletin# TSB3248. My 2009 Matrix 1.8L has already experiencing this kind of problem. I went to the dealer and they quoted me nearly $450.00CAD with taxes. Badluck for me, because my ODO already passed the 60K basic warranty so Toyota won't covered this problem. Is this a new Toyota quality?I'm not expecting this kind of problem,
    usually steering shaft a trouble free. I guess not many Corolla/Matrix owner whot got this problem, that's why is not worth to send this issue as a recall. I will send a letter to Toyota Canada, just to let them know what kind of problem I'm having with. :cry:

    I have had the same issues with my 2009 Matrix that I purchased in the fall of 08. Highway mileage is 16 to 17 mpg (if I am lucky and stay at 55 or 60 with the cruise control on). Toyota and the dealer handed me the same answers, the way I drive, the type of fuel, a break in period, the computer does not see any problems and on and on (my ML320 gets 26 mpg on the highway, da!). As a last resort I am taking it back this Friday to do a gasoline consumption test, and if that does not work then I am going to park it in front of the dealership with signs all over it stating the issues and the lack of results.
  • My car is doing this now. I have just under 56K miles on the car 2009 base model Toyota Matrix. I bought it new. My water pump was replaced courtesy of Toyota last week, and one of the bolts that holds the air bag bracket in place was loose and had to be tightened, but neither of those fixes took car of the sound I have when turning the wheels. What did the dealer offer as a solution to the problem?
  • mantechmantech Posts: 28
    The solution is, I have to pay for the steering shaft assy' approx. $270.00 for the parts and
    $200.00 labor. The Toyota Canada said: It is difficult to established the life expectancy of a component and predict when a failure occur. There are many variables that will contribute to their durability. :cry:

    Have a 2010 Corolla matrix. It is slighly less aerodynamic than the corolla sedan but same engine and same weight and the epa says the same city mpg but slightly less highway mpg. 26, 32. And 29 combined. 1.8 liter engine.

    I'm getting 22-24, with combined driving. Manual transmission. I don't do a lot of fast driving then braking. I don't rev up extremely high rpm in low gears unless I'm merging into freeway traffic. Normally shift at about 2500 to 3500 rpm. Bit higher on hills. So I don't know why my mpg is so low. Don't smell any gas leaks. Tires have precise psi.

    Just becuase the gas isn't leaking doesn't mean it is being burned. It could be drawn into the cylinder, but not fully combusted. In which case you'd have higher than normal carbon coming out the exhaust (black smoke) or could be entirely unburned and you'd have raw gas coming out the exhaust. I would however check for dragging brakes first.

    Try shifting at lower rpm's.
    "Moseying" along on flat ground I shift at 2000 rpm.

    I have a scan tool that gives instantaneous MPG.
    I found that on a stretch of flat ground at 40 mph MPG is higher in 5th gear than 4th.
