I highly recommend ScanGauge II, it's like having a vital sign monitor for your vehicle and it also can read and clear codes. Simply using it to monitor fuel efficiency and modifying your driving habits will pay for the device in a few months.

No luck, good discipline is needed. I've been using mine since November 2014 and average 36 MPG on a car that the EPA and manufacturer says shouldn't get over 32 MPG highway. Got 46 MPG on a 5 day cross country trip from Maryland to California on this same 2ZRFE engine, which is the same as a Corolla's.

Not to mention being able to diagnose my own trouble codes.

I love my scan gauge, that being said it won't help that much in fuel efficiency. Well actually it won't increase efficiency at all, but it can help you see your mileage if your vehicle does not have a digital display.

Absolutely, ScanGauge does NOT improve fuel efficiency, what it DOES is help you through changing your driving habits (if you are motivated and disciplined enough) which in turn can improve your gas mileage.

As I mentioned above, I have done this myself, and so have hundreds on the EcoModder forum.

Honestly I used mine for boost pressure / intake temp back in 2011 on the Mini S. Then sold the car and forgot about it for a long time. Then bought a new base jetta manual that didn't have a coolant gauge / boost. So installed and it works for that. It is hard to see sometimes in daylight and sometimes the "fast" refresh rate resets and I have to go back in and update it. But overall a good no hassle secondary gauge. I also now for another car use Torq app with bluetooth obd2 dongle.

I've had one of these in my Tacoma since 2007 or so. Great little device for adding extra gauges like coolant temperature, voltage, and intake air temp (usually pretty much the outside air temp if you're moving), and real time fuel economy. Also can be used as a speedometer if you have oversized tires that throw off your built in speedometer since it allows for tire size scaling on speed.

It's a bit of a hassle to use for any troubleshooting other than reading basic troublesome or clearing them. If you want to do more detailed troubleshooting, get an OBDLINK MX and connect to your phone via Bluetooth or local WIFI and you can do all sorts of stuff with various Mobile apps such as graph voltages of upstream and downstream oxygen sensors Vs throttle position, etc.

I feel like most people who drive moderately conservative already, me (ok like a grandma) and or do not modify their cars won't get much use out of this. Otherwise a $15 obd2 Bluetooth reader on your phone will troubleshoot codes and have the same live readings.

Don't let prius drivers see this fuel efficiency device, they'll slow traffic down even more.

This is worth the hundo and change so I can read the Transmission fluid temp on my 17 Nissan Frontier. The ChiCom bluetooth readers are fine with the Torque app, but you cannot get Trans temp with them. Solid deal here.

I'm glad to see deals like this on here. Long ago I ended up going with the ultragauge based on price. I learned A LOT about my driving habits by reading hypermiling forums and then being able to test out techniques using the gauge to measure. Still have it and use it to "get to know" a new vehicle. Squeezing a few extra mpg from a civic HX with low rpm peak torque is WAY different than a Miata with peak torque at at high rpm. All in all a really cool tool to have!

What makes this better than an OBDII reader paired with a smart phone?

Ha, I had one of these on my 1st gen Prius years ago, could monitor my fuel efficiency, but also more importantly, with community forums help was able to customize to decode State of Charge (SOC) of the hybrid battery, plus things like voltages of each of the individual battery cells. Later in the car's life, helped decode error codes for the engine.

Haven't used in years though, current EV doesn't even have a OBDII port...

I had one of these on my 5MT Impreza, and used the "fuel flow" gauge to learn what circumstances the engine would cut fuel flow during engine braking. This made it easy to learn how to decelerate without using fuel. With that, I was able to get my city commute MPG up to 30mpg from about 24mpg.
