:eek: I was going to say that you could have stretched it, but then I did some conversions...
16.9 gallons x 3.74 liters/gallon = 63.206 Liter capacity...and you filled up with 63.17. Yeah, so close--you should have coasted down a hill or something! :D
Good job though, I only got 598 miles this tank, but I was running B100, driving in the city, and doing some towing.
Cheers!

Nope...not even close...


...it's 3.7854118 liters. :D (Source: Google)

Edit: WHOA! Excuuuuuuuse me! Our very own "Unit Conversions" page lists 3.78541178.

Gads, you guys are too accurate. I was tired and was off by .04...don't remind me that I'm a pilot and I need to have these things right for fuel calculations!
So...63.17 liters divided by 3.7854118 liters/gallon means he put in:
16.687748476929247169356845139015 gallons...
So, 797.4 gallons divided by 16.687748476929247169356845139015 = 47.783558165584929555168592686416 MPG.

Still with me?
47.783558165584929555168592686416 MPG x 16.9 gallons in the tank (wish we had a more accurate measurement).
= 807.5413299838530948234921640043 miles before the tank ran dry.
That's 807 miles, 2858 feet & 2.66777693208801646351104 inches. I suppose you could coast another half mile or so if you were either going down hill or doing 100 mph when you ran out... Don't even get me going on what was in the filter, IP and lines! What this proves is that you chickened out and could have EASILY have done 800 miles! BTW, I'm on a mix of Bio and ULSD, driving to southern Utah tomorrow and coming back Saturday--I'm going to try 55 MPH and see if I can break 900. :)

OK, off to bed, I feel ridiculous right now! If any of you are so utterly lacking in having a life and check my work and find something is off, I really don't care. :p

So, the answer is I should've continued to make the 800 mile mark. Then either walk 3 miles back to the diesel station or try for the next one which was about 20 miles further on. And before we all start about turning back and driving back to the station, I was on a motorway, and to get back I would have to u turn 5 miles up the road, travel about 10 miles back to the last junction, and then 5 miles back up the motorway to the same station I just filled up at. Non of the above were particularly inviting prospects, given that I wasn't certain whether the tank was absolutely topped off when I last filled up.

So I made the right decision. And this current tank I'm up to 725 miles, and no light on yet, so I think I'll crack it with this one. Besides, I'm already a member of the 900 mile club from last year.:D

.... Significant figures..... eeesh.


I never posted here but my best in my 2000 Jetta was 815miles on some amount of fuel to put me at 53.9 MPG. I was only 25 miles into the low fuel light at the time.

This was with the vnt17 installed and goes to show that all the big turbo guys who complain about their poor fuel economy are just wimps. Slow it down and it will be there.

Ugh!!!!

I hate you guys...so very very much. LOL (Cartman impersonation.) I think there should be a 500 mile club for people with automatics. I hate my tdi for about 2 days after a trip to the gas station.

YOU'RE A PILOT??? and you screwed up a fuel volume-density question????

Didn't the Canadians crash a 747 due to that way back when???

And I only had to rib you on this because I'm an A&P-avionics tech that does 747 fuels every day. And you know us avionics techs-making pilots obsolete. LOL.

Yes...well...*cough* That's because we want you avionics techs to keep your jobs... :D
Meanwhile, I'm not flying 747's--yet. But soon I'll start flying the diesel twin!

I've heard of this aircraft. But is it turbo prop or turbo-diesel(i.e. piston)? The reason i ask is th elink you posted said turbo diesel but also said jet fue powered.

I've run Jet A in my Jetta on more than a few occasions but I always mix it2 to 1 with Desel No.2 and add a Cetan-lubricant fuel additive. Jet A has no lubricants and it's really hard on the injector pumps.

A co worker drives older (read that OD) diesel VW's exclusively on sumped Jet A. (how's that for low coast fuel? cheaper than E85 OR B100 lol) But every year he as to rebuild his injector pumps.

All this leads me to the question of I woner what they're doing to overcome this problem on the plane?

In fairness, I must tell you this...prepare to laugh...

So I was being "trained" in how to do fuels for Atlas Air cargo. I typically work on Cargo360 and Singapore Airlines.

Anyway, Atlas does everything in kilograms and litres. But the fuel truck pumps out in gallons. You have to match your calculated required gallons to what the meter on the truck says within 200 gallons.

No biggie right? The fuel sheet has all the multiplier factors. Besides, I just use a T1 36x scientific to do all the work for me right?

So this old guy mechanic was going to show me "how it's done."

First of all, he did the math 3 different ways, using 3 different fuel densities.

I'm like ***? He said "sometimnes their fuel density is off." and I'm like "and what? you have a barometric tube in your head that automatically calculates fuel density for you?? Yeah nevermind the computer, you just "know."

So he corrected my calculated required fuel by 6 gallons (I did't carry the 4th decimal point, I rounded.)

When it was all said and done, he starts telling the fueler to add fuel in 100 gallon increments. About 250 gallons later, the Flight Engineer comes out yelling at him.

He overfueled by like 3000kg. We were like another 100 gallons away from being over max TO weight.

The punch line to this diatribe is that hte F/E said to him "geee, I wish someone here knew what hte F---K they were doing!" I'm so glad he was holding the fueling manual. LOL

He threw down the manual and looked at me and I siad "hey, YOU'RE teaching ME, remember?"

Always do your own work, the other guy might be an idiot.

I wouldn't, unless you have a spare gallon or two in the trunk and are willing to risk running it dry.

1 US gallon is by definition 231 cubic inches, which works out to 3785.411784 cubic centimeters. One liter is by definition a 10-centimeter cube.

This reminds me of the number pi though. People memorize it out to outrageous number of decimal places(cause its fun) when in reality. Pi to like 20 decimal places is enough where you get down to the point that you realize everything is made up of molecules and they arnt even round os it doesnt really matter.

My record was pi memorized to 130 decimal places.

I bow to the mega-nerd. I only know it out to ten digits.

Actually, I know the exactly correct value for pi (to an endless precision and as many decimal places as you want)....it's

circumference/diameter of a circle. :D

well, i don't have a pic yet to prove it... (once i get my new computer i will) but my low fuel light came on at 820 miles and 843 miles on it now. probably 1.5 gallons left... wooooohooo! :D i would go for 900 but it will be just short trips now. and this tank wasn't all straight highway either! :) just kept speeds down for the most part to 55-60, but some 65-75mph

I wouldn't have believed it if you told me, but the RocketChip DOES improve fuel economy. So much so that I went from 51.2 MPG on my last tank to a new record of 54.75 MPG! And on top of that, I managed to go the magical 800 miles! 808.7 miles on 14.772 gallons of diesel. Honestly, if you have a mainly stock A4 like I do, get the Stage 2 chip. I got this doing anywhere between 65-70 on the freeway, and about 50 miles of city driving. I just don't have the words, I am stunned. Happy, but stunned. :D

:eek: Are you serious, or just distracting me while someone sneaks up behind me with the straightjacket?

BTW, I'm a bonafide member of the club now.

813 miles

Just posted in the 700 mile club, then I saw this. I was so excited!!!

A picture is worth a thousand words. How did I do it? 50-55mph some rural hiway, the rest major interstate. I do not know my exact mileage as I had to get fuel at a commercial prepay pump so I did not get to fill up. Bummed!!!!
