700\17.2 =40.7mpg

700\41mpg = 17g

Do you 700 mile guys go all the way to 700 or is it a theoretical 700 miles? I averaged 41.666mpg on my last tank (calculated by hand).

That would put me at 41.66*17.2=716.75 miles theoretically. I filled up at about 558 miles.

 

I'm going to easily hit 700 miles as my reminder light came on just briefly at 610 miles and is currently off. I suspect it will come back on and stay on later today. As a 700 mile member...I have always run to the 700+ mile mark (not theoretical). I should easily hit 710 miles or higher depending on my EV abilities and anticipate still having nearly 2 gallons left in the tank. I don't run on empty. The most I ever got in the tank was 15.6. I'm currently at 47.04 mpg assuming 15.2 gallons used and 715 miles on the trip meter. I won't know for sure until I fill up tomorrow. I just figured out how to add my car to the Real Hybrid Mileage Database. I will be posting my numbers from now on. If I theoretically calculated my numbers...I guess on this run I would hit 800 miles but I would be coasting into the service station. That will never happen. I have never in my life run out of gas.

I've learned some more new things about my driving habits and environmental effects:

1. I goes to work in the morning going south...but the winds are generally decoupled so no additional wind resistence. In the afternoon...when the southerly flow strengthens, I actually get a tail wind on the way home.
2. Flat surfaces in general, I have choices on the way to go home but I choose only the flatest route that has a speed limit of 40 miles per hour in the city and 55 on the highway.
3. I let the cruise control work on the flat surface 51-55 miles per hour and usually set at 39-40 miles per hour in the city.
4. On the highway...I let cruise control work with preferred speed 55-60 depending on traffic conditions.
5. I turn off cruise control on 2 of the hills on the way home...and do not let the mpg reader hit much less than 20 as it consummes more gas below 20. I will bring it up above 20 and as the mpg reader swings to 40 miles per gallon and I then again accelerate through the hill to 20 and repeat to get over the hill. Therefore I stay around 55 to 60 miles per hour and use less gas.
6. When starting out in the morning or afternoon after the car has cooled, I use Step 5 to bring me up to speed without using a great deal of gas. Then, I put on cruise control.
7. When the car has warmed (about 3 miles down the road), if I encounter traffic lights or slower traffic than myself, I will ease off cruise and glide down to 40 miles per hour and in EV mode until is is okay to speed up again.
8. I use ECO air only or no air when I don't have passengers are in the car.

The latest tool in the gas saving tool bag, it to set that cruise control on flat surface and let do its thing. I have seen improvement there.

 

I am not a "700 club" member either -- but I have done 682. I think the thing is not to push it too hard just for a very trivial goal. I know I will get to 700 sometime or another when the season, weather, traffic, trip and timing is all correct -- and I will do it without using the last fuel in the tank. It is simply not worth the consequences and extra work to set it as a goal and pursue it.

 

I'm pretty conservative and usually fill up shortly after reaching zero miles to empty. After over 200 miles on my current tank, I'm at 48.0 mpg (displayed) so if I'm ever going to do it, this is the time.

I think a favorable commute plays a big role...15 miles each way on the DC Beltway and some four-lane roads (averaging about 25 mph), with a few hills to recharge the battery after cruising in EV. The hills are such that I have a few good downhill runs after these EV-charging climbs, allowing one to offset the other.

I accelerate briskly to get up to speed and then ease off the gas to maintain speed. I rarely have the chance to use cruise control.

Springtime temperatures in the 70s really helps, too.

 

It's real-world miles traveled between fill-ups. I swung 4 700+ miles tanks last summer. None the first summer because I hadn't figured out "full hybrid mode" or found my new standard commute route, which is a small amount of highway and mostly suburban roads with speeds 30-40 mph for lots of EV time. Even with some solid hills. I'm already edging toward (nominal) 42 mpg this tank and the weather's not really even that warm yet. My next tank will probably get me back in range for 700 mile tanks again. But yeah unless you're well within range of an 800 mile tank, you probably want to keep verifying the math if you care about seeing 700 without running out (or just sweating the last miles lol). Running dry is bad, m'kay?

 

I have been keeping very good records on my mileage. I always have about 2-3 gallons left in the tank. I guess I am a chicken **** to keep going. I may keep pushing gently on my threshold for where I will fill up. Maybe...maybe not. I don't care if I can make it or not I guess. it's just nice to know that I could.

 

I never really pushed my mileage for any sort of thrills. I just drive conservatively, know my way around town, understand the vehicle dynamics of the TCH, and mostly stay well within EV speeds. I am inching closer to 800 miles. I kept my receipt for my 19.2 gallon fill-up. I have shown other Hybrid owners, and they don't seem to disagree too much about the validity of it. I have had friends personally witness 18+ gallon fill-ups with me. The car itself does an amazing job, and I am just the lucky person in the driver's seat along for the ride!

 

19.2 gallons? Must be draining the fuel line and driving on fumes then eh?

 

Or buying gas in SE Georgia, off I-95

(where several folks have been finally charged with short-pumping by qt/5 gal, and likely shorted their customers by more at various times).
