It only has phase 1. I'm waiting a month or two for phase 2.
Today I was able to get 900+ miles. I'm honestly surprised I was able to get it because this week I had a lot of idling and city driving when taking my daughters to their activities. This morning I was able to get my best 66.6mpg (realistic 62.6 mpg'ish b/c trip meter off 4+- mpg). On Monday I got 64.5mpg (60.5mpg).
On the way home when I started up my car I had 55mpg till empty, but I know getting out of Orlando city traffic was going to eat up a lot. It actually went pretty good getting out, but I did have to turn off my AC in the rain once I started driving on the highway. It actually felt pretty good b/c no water was getting it I just cranked them down a tad while driving to make sure I have enough to get home (62 miles). Unfortunately there were 2 wrecks that slowed traffic down, so when I was 22 miles away I hit 0 miles. I know there is about a 1.5g fuel reserve, so I wasn't too worried about running out. I was going to stop just as I passed 900 miles, but fuel was $3.44 off the interstate. I decided to just drive by my house b/c it was only $3.04 a gallon. Needless to say I was really pushing it because I almost pumped 18 gallons. I've never pumped more than 17.2 gallons before.
I know I'd be able to get 1,000 miles, but I will not try it till my daughters are done with their swim lessons, because that's twice a week I have to deal with city driving for the next few weeks on top of the other day I take them to gymnastics. I actually drove a little faster when I first started this tank, but it's kind of nice to drive a little slower in the morning. I usually get to work around the same time, maybe 5 minutes more, get to work safer, not rough on my car since I'm not using a lead foot. I rarely have to tap my brakes other than normal red lights/stop signs, so I'm constantly driving, unlike when I'm going in the fast lane. It actually seems to help traffic with less congestion, because people are able to to get over and pass if they want to, unlike when all 3 lanes are moving the same speed, or there is a person like me in the fast lane, lol. If someone is driving slow (but a little faster than me) and wants to pass me then traffic in the middle lane is moving fast enough that there isn't an issue, because they can still easily pass me and then move back over without causing congestion. If there is a slow person in the middle lane then people can move over to the fast lane or pass in the slow lane because no one is usually around me.
Whenever I go for the 1,000 mile tank I'll probably keep AC off in the morning and just crank the windows down just a tad, since it's still super early in the morning and pretty cool still. I'll keep my speeds slower from the start. As long as there aren't any major accidents it should be pretty easy. I basically got two extra days (8 instead of 6) of driving for free, because my fill ups are usually around 680-700 miles with 30+- miles left till empty.
