Steve, I'm trying to catch up with you.

That may never happen though.
You are averaging 56.9 MPG.
And that's with 12 tanks.
I only have 4 tanks with 54.5 MPG.

BTW I use cruise control 99% of the time on the freeway (53 MPH).
I don't do the "drive with the load" thing yet.
Maybe that would help.

It is the city miles and short trips that kill my MPG.

Yea, that's hard on everyone.
You might catch up with me soon though.

Monday morning I raised my tire pressure from 32 to 40 psi, (sticker says 30, tire sidewall max is 44.)
Now it's Friday so I have one week of data.

Here is this week's MPGs for my morning commute of 17.2 miles:

Mon 61.3
Tue 63.5
Wed 62
Thu 60.9
Fri 65.3

I have no idea why it varied to much.

This is 97 % freeway at a cruise control setting of 53 MPH.
No hills, but not absolutely flat.
No driving with the load, just cruise control.
Temp about 65 deg, no rain.

BTW my tank so far is at 59.8 MPG with about 70% used.
I may just get a 60 MPG tank afterall.

Hi Kenny:

___From 59.8 mpg to ~ 62.6 mpg or so appears to be an ~ 4 + % increase which sounds about right. You are doing better then great actually!

___By the way, let me officially welcome you to the “Hyper Mileage Club” as currently occupied by Rick Reese (Insight and Prius I), myself (Insight, Corolla, and MDX), Ericbecky (Insight), Hot_Georgia_2004 (HCH), Gshepherd (Prius II), Jjmcubed (HCH), Buzz70 (HCH), Mrkcohen (HCH), Livvie (HCH), Texashchman (HCH), Videian (HCH), Kabel (HCH), Rpdog (HCH), Jinno (HCH), and Brian Maher (HCH). To belong to this unique but exemplary group of “characters all you need to do is maintain > EPA combined estimates tank over tank over tank. I know quite a few more Insight’ers and I am sure many know even more HCH, Prius I and II, as well as Diesel and SI ICE automobile owners that belong to this club as well but I haven’t seen them post over here just yet? I only hope I didn’t miss anyone given the many real mileage database overrides and actual combined EPA estimates of the non-Hybrid’s listed …

___The official motto? Let me steal a line or two from the unofficial motto of the US Postal Service …

Neither snow nor rain nor heat nor gloom of night stays these Hyper milers from beating EPA estimates on their appointed daily commutes and leisurely drives …

___I spend entirely too much time on the Internet I think

___Good Luck

Thank you Wayne.

I have no patience for the cry babies who say they can't get the EPA estimates.
We are proving they can be met and exceeded by a significant margin.

Kenny,
It is interesting to see the variation in the same trip over time. My round trip to work this month varied 74.4 to 83.6 so far.

As far as "Hyper Mileage Club” goes...
I'm a little worried that when winter rolls around, that I will not be able to keep above the EPA estimates.

Looking back at my data I show that I had a few tanks in the low 60's and even one *GASP* 58 mpg tank.

These trips down to Chicago aren't helping either. Too much time going 65-70 miles an hour on the interstate are dragging my tank mpg down.

NICE ADDITUDE GUY.

That is really a solid way to win friends and influence people.

A+ on your mileage

Hi Eric:

___Since Lamewing popped this one back to the top; I thought I would add a comment or two.

___Why not pull that Naperville and back run at < 55 mph the next go around. I haven’t missed a 100 mile segment in over 8 weeks and I am sure you will gain your first if you just slow her down a bit. If it is less then 75 degrees F, you can leave your WAI and Radiator block installed as well. There has been Easterly/Westerly wind directions vs. the normal North/Southwesterly around the bottom of the lake as of the last week or so which does not help but 100 + mpg over your segment is still quite doable. Call me before you make the run unless you have already left for the weekend and I can give you a few tips about how to handle the terrain after Rt. 132 (Grand Avenue Exit) on I94 out to I55/I355. The killer climb really starts on I55 from the I294/I55 toll booth and you can bypass some of it by taking I88/I355 instead.

___Good Luck
