CleanMPG Fuel Economy Challenge V - Spring 2009

1/8 of tank to go (dummie light came on coming home) 395.7 on the ODO
SG says 21.8 MPG:eyebrow:

I will fillup by this weekend to have this tank in this challange and start fresh for Challage of the SUMMER summer summer :Banane18:

 

I'm at about half a tank now. Not entirely sure if I will be filling up before the 1st or not. It probably depends on whether (or where) I go fishing.

 

This estimate is going to be low on the miles already. Had two unplanned trips yesterday. Average mpg was around 74. Will post cumulative tank average tomorrow. And oh, remember my SG numbers tend to run 4% pessimistic. With luck, I can multiply my mpg by 1.04. (where is the crossed fingers emoticon?)

I'll probably have another tank in addition to the one I'm posting in a bit, I don't like hovering low.

 

from the record of this tank in the spreadsheet it says I have 2 gals left (plus what I put in the filler neck) and I usually use 1.1 or 1.2 for the trip to and back from work so I should have enough to get to the dino station, but if you hear a loud out cry of NNNNOOOOOOOOOO!!!!!!! in the after noon it will be me running out of gas

odo is at 422.3 and the needle is just at the start of the read line for Empty.

BTW the SG still says I have 6+gals left

:Banane18: gotta flap my wings FAS'ed

 

I won't be filling up again for this run as I only have just over 200 miles on this tank and there are only 2 more days left.
That means that third place in Div. B is up for grabs.
There are a few people that are within striking distance if they have one good tank left.

 

I'm giong to go ahead and fill up this weekend.

Finish up this run, start the next one fresh, and with a good run so far (almost 38.0) I might be able to edge up the 1.23% I need to reach my goal of 150% for the run (with over 4000 miles already I won't be able to go up enough to catch anyone).

 

I'll fill up once more, but I'll just crack 160%....for the next run, all blood sweat and tears will be shed

 

Well, that will put you ahead of me for this run! well done! you may need more than blood, sweat , and tears to beat me this summer though hehe

 

I made and only put in 19.052 gals. This is suppose to be a 21 gal tank, I think it is only a 19. If it is a 21 then I still had 3+ gals left but the needle was on the bottom of the red line. I wonder how far I can go under the line.:eyebrow:

Ok here are the numbers:

19.052 gals (most ever filled)
445.4 miles (longest tank)
23.38 MPG (most EVER!!!!) that's 156% over EPA combined :woot::Banane18:

The Summer gas must be playing with the SG as the number were way off and the Change at fill up went from 20.1% to 39.4%

Up more 2% to finish the challange but no change in status. I end on 140.81%

Now if I can string more of these tanks together

 

Nice work, Jason!!

I would bet that needle can go quite a ways under the E mark. Mine went a good 4 needle widths under it (as in, that's the space between the needle and the E mark) before it finally started sputtering. That's why if you check the logs you'll see I put 17g (yes, I stuff) into a 14.5g rated tank.

Even my Insight with a digital bar fuel gauge works the same way (though I can't see anything below the bottom) -- after the last bar goes out I can still travel about 2 bars worth after that before she starts hesitating.

 

Nice work Jason! i find most vehicles have another 2 gallons or so once the gauge says completely empty

 

If you can find out the PID for your fuel tank reading, there is a way to KNOW where empty is:

1.) Program your SGII with that query and start monitoring it.
2.) Fill a small gas can with 1 gallon of gas and keep it in your vehicle.
3.) Watch your gas count response. When it stops changing you are nearly empty.
4.) Dump the 1 gallon in the tank and immediately refill.​

For those who are adventurous, you can take it beyond that point and discover true empty. However, you will be vacuuming up all the junk in your gas tank sump onto your filter and reducing fuel pump cooling - potentially affecting longevity of your fueling system. I highly recommend against it.

BTW, it would be a great idea to mark your empty PID response count on your gas gauge with a permanent marker.

 

I just entered a hypothetical tank based on the miles I have driven so far, and seeing as drummerboy just entered what appears to be his last tank on the challenge I should win if the SG is accurate enough. I will be filling and entering the actual numbers by Sunday.

ETA: I deleted the hypothetical tank for the time being to avoid any confusion.

 

Yesterday I removed all aerodynamic helps, inflated the tires (only one lost a little pressure) and washed the car. This morning I put back the rear skirts (now a little closer to the wheels) and the upper grill block (modified so I can open the hood

I have to leave this after-noon for a little trip and come back tomorrow morning (directly to work . I will not be able to do the whole trip with the remaining tank so I'll fill-up (*) when leaving today. I won't be able to report this last tank for Spring challenge before tomorrow evening.

Odo says 1153.3 km and guessgauge between 44 and 45 l ie 3.8 - 3.9 L/100 ie 60 - 62 mpg, so it should be better than my current average, but worse than my last tank : got more city/traffic driving than usual.

After last tank report, crazy me will subscribe to summer challenge into div A

When back from the trip, I'll fill-up (*) and will report this first summer tank.

(*) I'll fill-up at top these two tanks and all following tanks. For 1st top fill-up, I'll enter gas volume of 2nd tick as usual until now. I may not do my longest tank attempt immediately, as I will have to carry the car to the garage for a maintenance. I'll ask about going from 5W40 to 5W30 this may be, with the next aero help I'm preparing (full hubcaps), helping me enough to achieve a kilo-tank.

Denis.

 

Well... I made my final fill. I didn't catch anyone (like I thought that would happen), but I did manage a new record and met my goal of 150% for the challenge.

332.7 miles, 8.595 gallons.

38.7 mpg!

That finishes me off at 150.05%

It's also the first time fueleconomy.gov gave me the red flag saying I got too much FE.

 

Just filled and entered my last tank for this challenge. It seems that drummerboy has also entered his last tank. I was just able to squeeze by him. I was able to pull a record tank for my last one, so I think that helped.

608.1 miles
14.709 gal
41.342 MPG

 

The time has come, the walrus said, to pay the piper; to mix a few metaphors.

I have entered my last tank, and I am a pessimistic estimator. Actual numbers were 75 miles and 0.57 mpg above my estimates.

601.6 miles at 9.399 gallons = 64.007 mpg. Still, i tbrought my average down .3. Since Monika drove 80 mil at 43.2, that means my 521.6 was at 69.11. That puts me at 214 and some fraction % of EPA.

I did some back of the envelope calculations, and Andrew needs something better than 70.4 on a tank of more than 775 miles to pass me. C'mon Andrew, lets see what you can do, I know it's going to be really close (unless he just blows me away! )

This has been a great challenge.

I tell you what, if you want to get a phenomenal tank, compete against Wayne Gerdes for a weekend (our two days weren't on a real weekend but on my day off so it still counts), but handicap him, put him in a car that can only compare to an HCHII with him at the wheel.

 

I filled my tank before 12 hoping it would combat your fuel-efficiency rampage, but I was shy with a 159.42% compared to your 159.7%... I guess I will just have to try harder next time... good job, man, you did great.
