Stats and Standings: Beginning July 2, 2007 - Gas Savers

rh77 · 07-19-2007, 04:27 PM

Hey FETC Challengers...

Here's the new spot to report weekly accomplishments or tank updates. As soon as I get off my lazy bum, Cycle 3 updates will be posted. Good luck!

I filled up last night. I travelled 388.0 miles and used 4.78 gallons for 81.17 mpg. I'm going to Hybrid Fest 2007 and I'm leaving about 6:30 pm Friday and coming home Sunday. This highway trip will pull the numbers down a bit but I'm hoping for 75 mpg on the tank by the time I get back.

jwxr7 · 07-24-2007, 07:07 AM

filled this morning. 606.3 miles on 8.713 gallons = 69.59 mpg. I fell below 70

, I blame the 200 miles of highway driving I don't normally do that was on this tank

(55-60 mph min with no EOC ops + some wot to 60 mph merging with semis). Yeah, excuses excuses.

s2man · 07-25-2007, 02:22 PM

Commish, does this mean we don't need to report to our team captians anymore, just post it here? Here's my latest:

Porthos, Team OPEC Busters. 07/23/2007, 445.116m on 13.11g for 33.93 US mpg.

Not as good as last week, but still better than my pre-mod PB. Mods this tank: 40psi in tires, partial grill block, shaved passenger mirror.

That's right -- with several teams, updates are based on actual GasLog data (easier and more accurate). Which reminds me, current stats/standings should be updated in the next day or so...

Keep up those great tanks...

brucepick · 07-26-2007, 02:35 PM

Commish,

Since you're getting the data from the Gaslogs, I have to ask -
Per each car, are all miles equally weighted? That is, are you totalling up all the miles and all the gallons then dividing? That method weights all miles and gallons equally for that car.

Or the alternative would be to grab the mpg values directly off the gaslogs, and average them. That method weights each tank equally - so a short tank of only 4-6 gallons and maybe 100-200 miles would have as much "weight" (significance) as a long tank of 10-20 gallons and many more miles for that same car. If the short tank was unusually high or low mpg for whatever reason, then the short tank skews the results.

I had to ask....

rh77 · 07-26-2007, 06:57 PM

Oddly, no -- it doesn't. The tanks are averaged regardless of cumulative distance/consumption.

Manual calcs of the baseline use the same technique.

As I think about it, this is an excellent point. With the data extraction that I receive, it would be simple enough to implement the cumulative procedure.

If everyone is cool with the new plan, it will take another week to get an approximate stats/standings published.

Standby for a poll...

Jim Dunlop · 07-28-2007, 07:37 AM

I agree. The only way to do it and be objective is to do it per total miles...otherwise some joker with really good MPG could fill up 3 gallons at a time to increase his/her team's stats.

I myself am considering 1) "calilbrating" the lower end of my gas gauge (i.e. when needle was at 1/8 it took 9 gallons to fill), then 2) making a drop down in fill up volume by waiting until the needle hits 1/8 and only put in 4-5 gallons of gas (the same amt every time). This will lower my vehicle's average weight by 20 lbs. or so and potentially increase FE.

LxMike · 07-29-2007, 10:47 AM

Sg ws showing 37.x and when i refueled i made sure top click it at least 2 times to stay consistent and recorded 318 mile- 7.70 gallons of gas. 41.28.

CO: what do i ned to get a cd??

You just did it. Congrats. PM me.

rh77 · 08-05-2007, 09:56 PM

Hey competitors...

Cycle 3 is almost over -- so here's the "mid-cycle" report

Sooo...

Sorry about the delay in the report. With the new cumulative percentage, the 90-day averages had to be manually calc'd and that takes some time.

Without delay, here we are, as of July 30th:

1. Team OPEC Busters: 6.4%
2. The Right Lane Rollers: 5.5%
3. Team "Leftover Bananas" 4.0%
4. The GasMisers5: 3.9%
5. Team Slow Burn: 2.4%
6. Team Feast & Famine: -3.2%
The spreadsheets are attached...

For the Cycle, this is the last week folks. TCs: ensure your team has 5 members, all of which have a 3 gallon fill reported by this Sunday Aug 12 at Midnight Central Time.

The new calculation method takes the total miles per total gallons.

Best FE!

Commish

Bananas are 3rd! Go Bananas! Must get in 2nd place!

Commish

Let me know if you need help with writing a script to "automatically" calculate the information. It seems like you shouldn't have a problem as everything needed is stored in your gaslog DB.

brucepick · 08-07-2007, 08:03 AM

Been getting between 31-32.4 mpg steadily for about a week now. I have a couple new tires coming in, should be going on the car Thurs or Fri a.m. They will allow another 4-5 psi so that should be a good thing.

This a.m. when I got close to work I realized that the spare piece of coroplast in my car would probably be perfect for a short version of jwxr7's Kamm back (see http://www.gassavers.org/garage/view/272 ).

So I built it. Sorry, no pics yet. It's short, only 6" from the roof's rear edge but hey, better than nothing. Maybe it will help pull Team Leftover Bananas up into second place!

It took an hour + ten mintes, including time to duck into Home Depot to buy a coroplast sign to get a bit more material. I always have duct tape in the car nowadays! There's a Home Depot and two thrifty gas stations right outside my work entrance, very convenient.

Go Bananas!
Ya gotta watch out for us, we're a slippery bunch!

OPEC Busters, I think this guy is talkin' some smack on this competition. And I ain't gonna take it sittin' down. This weekend I'm puttin' in the new ignition system and wheel bearing, for sure. And the LRR tires will be right behind that.

Bust 'em up, OPEC Busters!

DaX · 08-07-2007, 12:55 PM

Let's go Slow Burn! Way to go on the best % jump so far James. We are missing Driver #4? ...so we get a zero calculated into our average?

Ya best be quick with that work. Per the Commish's post #11 above, this round ends "Sunday Aug 12 at Midnight Central Time."

Anyway, nothing improper was intended when I said we're a slippery bunch. I just can't resist a pun, ya know? I hope we'll just s - l - i - d - e into the 2nd place slot.

bbgobie · 08-07-2007, 01:36 PM

Dang... Dragging down the bannana's. Gonna have to drive around in circles for no reason! Just like burning off the extra turkey you know you shouldn't have eaten after thanksgiving!

jwxr7 · 08-08-2007, 05:53 AM

new fill this morning, 528.45 miles on 7.410 gal = 71.316 mpg.

Bill in Houston · 08-08-2007, 06:55 AM

Two tanks in a row over 28 mpg! Okay, for most of you that's nothing, but for me, it's a first...

Maybe not worth a CD of cowboy songs, but I'm happy. :-)

Bill, that is good. I've wanted to ask if you are using your air dam now?

Sounds like maybe you are driving quite differently now?

PM address. All members, especially from Texas, need Cowboy Songs.

Thanks! I am not using the air dam right now. With the belly pan on, it seemed that maybe the air dam would be doing more harm than good. I have an interstate trip coming up that will be a good test of my aero properties, and I will make a judgement on the dam after that. That test will be 70 mph, A/C blasting. No technique allowed when the family is on board. If I end up putting the air dam back on, I hope to motivate myself to A-B test it with the belly pan in place.

With my family having been out of town, I am able to coast a little longer/slower, P&G a little more, time lights a little better, etc. So, I think part of the gain is attributable to technique improvements.

I'll PM my address. I'm looking forward to the CD. Thanks!

Nothing improper taken, Bruce. I was just trying to stir the teams up ;-) Good luck with your mods.

LxMike · 08-08-2007, 04:32 PM

arggg! battery died on me last week. Then brake light was staying on and had to disconenct battery at work till i could get home and found it was a lil rubber piece that is on the brake pedal. now my scangague is all messed up so i'm not sure how good i am doing. currently at 110 mile with needle just under 3/4 tank left. going on a trip to the drag strip friday if weather cooperates.

s2man · 08-09-2007, 07:35 PM

I've just entered a new Personal Best in the garage. 473 miles on 12.6 gallons for 37.47 mpg. Mods on this tank were XcelPlus Lubrilon engine treatment, and lower oil level in engine.

Oh yeah, Go Team OPEC Busters!

Good work, Man -- hail Porthos!

How is it going with the heat? Today, something melted on the hatch latch and it's busted

. I mean, it's not any hotter here than many parts of the Country, but lately it's been noticeable...

bbgobie · 08-10-2007, 01:47 PM

Stupid question. But 12 Midnight means Sunday night right?

Might have to make a trip to Hamilton Sunday morning to go check out a used road bike, which means 1hr hwy each way. Last ditch bannana tactic!

landspeed · 08-10-2007, 05:30 PM

Latest tank - 567.5 miles 10.346 gallons 54.84 MPG(US)! (for 149% over EPA). This is my best ever tank, and the last 3 tanks have each been my best ever tank

Go GasMisers 5!!

brucepick · 08-10-2007, 07:29 PM

Arrrghghghgh! Several short trips needed to repair broken side glass on wagon - slid on wet road. The rainy days also took their toll, tank was 29.04 mpg. Last tank for this FE Challenge for me; wife and I are off for the weekend in a rental car with a/c; ours have no a/c.

I still say - Go Leftover Bananas!!!
