Auto Meter 9105 ecometer Fuel Consumption Gauge

Product works well. I have been using it for the last 3 months on my 2008 Honda Odyssey minivan and have put a few thousand miles on it. Correction factor of 0.93 or 0.94 seems to work for me.It showed me which trips were most wasteful on gas (I was getting single-digit mpg average in the city where I live), allowing me to replace those with bike/scooter/transit.It also showed me that disabling Honda VCM on my engine did not greatly worsen mpg, and was well worth it, for addressing high oil consumption, fouling of both catalytic converters, and non-smooth driving.Also helps as a reminder to keep the speed down on the freeway, as mpg starts decreasing rapidly above a certain speed (or if there is a strong headwind) that makes the little bit of time savings not worth the extra fuel burn.UI is a little confusing, but I keep the manual in my glovebox for reference.If you need more attachment strips, it's 3M Dual-Lock, also purchasable as "Scotch Extreme" fasteners.

The Quality is good but what's lacking is a solid base on the unit. I used two command strips to get the job done and it worked really well in my opinion. It's easy to use after you read the instructions that come with it. Readability is very good and the brightness can be adjusted. Performance well it works. The size is misleading, it is small, I thought it would be bigger but for It's size the readability is very good. I drive a 2013 Chevrolet Silverado LTZ 5.3L V8. I use the instantaneous mpg setting. I noticed when you start your vehicle the meter displays the yellow and red bars and the numerical number is at 0. Once you start moving the red bars disappear then the yellow bars slowly disappear too, and the numbers start increasing. Once I'm in 3 gear the green bars start showing up.

I just purchased an older Expedition that didn’t have the display for mph. This fit the bill to give me this information. Autometer makes high quality products

keep in mind that this is strictly my opinion and opinions are like armpits, everybody has at least one. this device does not do what i want it to do. i bought it hoping it would tell me what my MPG would be no matter where or how i drove my car. instead i had to adjust parameters several times before it got anywhere near what my car's actual MPG should be and it still does not do what i want it to do. i will never again buy a device such as this. as the saying goes...fool me once, shame on you, fool me twice, shame on me. well, you won't fool me twice with this piece of junk. i doubt that amazon will allow this and they might stop asking me for reviews and that's o.k. too, but just putting it in print makes me feel a little better. the only reason this device got one star is because there is no provision for zero stars. if you don't like this review, ignore it, but don't complain to me. like i said, it's just my opinion.

Do wish it was a little bigger but it's pretty accurate for rpm, and mpg lights up decently

Works Great on 2014 Taurus. Simply plug in and mount using the included EZ Pass strips. The newer Fords are known for having inaccurate analog speedometers and I don't know why that is, but when this is connected via OBDII, the speed matches GPS. Only the PI's have the capability to display the digital speed, not the consumer models so this solves that problem.

I bought this for my Honda Pilot.I was hoping I could regulate my driving style so as to increase my MPG.Alas, it seems the Pilot is a stubborn creature, and it was determined to get the same mileage whether I drove normally or like a little old lady.I got rid of the Pilot and got a Prius.It did work as advertised, however, so it easily earns 5 stars. It took about 3 tanks of gas to get it calibrated, and it was kind of a pain, as the OBD port is not meant to have things plugged in and pulled out repeatedly. Still, once done, it's done, and gives you accurate readings.It's easy to use, easy to reset, and the display turns and dims to suite your tastes.I've found it just as accurate as those built in to the Honda Civic and Toyota Prius. Of course, the built in solutions have more goodies, but this does just fine with what its got, and it's a heck of a lot cheaper than a new car.I kept this, as I plan on buying an old truck to offset the not-manliness of the Prius, as well as to haul big stuff around. If said truck happens to have an OBD port, this will come in handy.If you are like me, and you require a visual aid to assist you in driving a little less, eh, awesome, this is a great way to get that.

2012 Tacoma 4.0 liter. This gage is quite accurate after carefully tracking the mileage and adjusting the Efficiency calibration number (follow instructions closely). This thing gives you a great feel for how much gas your using at all times and during all conditions. Great tool for the money. It took me about 6-7 tanks of gas to get it dialed in. I've been using the exact same gas pump for consistency. The most recent tank I had the Efficiency setting set on 91. The miles were 245.4 used 14.71 gallons = 16.68 mpg. The Ecometer said 16.7 mpg. The farther you run your tank down, the more accurate the data. Don't expect to get the calibration perfect within 2-3 tanks like the instructions say but that's to be expected with the accuracy. Great product. Highly recommended. I bought one for my son also.
