70 MPG US (3.3 L/100 km) challenge (non-hybrid gasoline and diesel cars)
 
1 Attachment(s)
I'm going to record a 70 MPG tank (someday). This is an invitation to anyone else to take up 70 mpg as a challenge, too. Score at least one 70 MPG tank or single run average anytime, year round, and you get inducted into the 70 MPG Club. There are vehicles on EM that have done much better than 70 mpg on a single tank, but only a few. And to my knowledge, only basjoos's "AerocivicLB" and funkhoss's "The Little Car" have ever achieved a Lifetime Average of 70 mpg or more. Their prize is community legend. For the rest of us, to commemorate our rare status, we will get digital prizes, such as being added to "The List of Winners" below.

THE LIST OF WINNERS (in no particular order):

1. FTA (Full Tank Average)

Lupo 3L --> 2L ('00 VW Lupo diesel)
PaleCivic (96 Civic DX)
His Benny ('06 Honda Insight, dehybridized)
PaleFit (08 Fit Sport)
Winter-beater-Metro (00 Chevy Metro)
BlackFly (98 Pontiac Firefly / Chevy Metro)
Mirage #2 (14 Mitsubishi Mirage SE)
Sport Coupe (92 Ford Tempo GL)
AerocivicLB (92 Civic CX)
The Little Car (00 Chevy Metro)
Nut Wagon (91 Civic Wagon DX)
Daox's Paseo (97 Toyota Paseo)
ecoDrudge (07 EU-spec Ford Fusion TDCi)
Even Fancier Metro ('14 Mitsubishi Mirage)
...others...?

2. SRA (Single Run Average)

Swarthy (14 Mitsubishi Mirage DE)
Black & Green (98 Honda Civic DX)
GreenTDI (11 Skoda Fabia Estate)
K-sight (00 Honda Insight, de-hybridized, with a K24 swap)
Smart Car Diesel ('06 Smart ForTwo Diesel 6MT)
Lupo 3L --> 2L ('00 VW Lupo diesel)

... others ...?

TWO PRIZES
Full Tank Average (FTA) gets this picture of a hat:

I'm guessing de-hybrid-ized cars don't count? :D

Shaneajanderson 07-02-2019 01:39 PM

At this point I'll be glad to get my Metro to 50 by the end of summer, right now averaging 38 mpg, but I drive lots of hills and the engine needs a ring job about 40,000 miles ago, I think I have more blow-by than compression.

Even at 38, it has cut my fuel costs nearly in half over driving the Buick I had, and my pickup would cost me nearly 4 times as much if I had to drive it every day.

Hell yes they count. Let's get the unofficial EM 70 MPG Club off the ground with some former hybrids in the mix!

fusion210 07-02-2019 06:14 PM

Heck, I'm just trying to hang onto #10 of 10 in the top hybrid list!

Good luck, looks like you've done it once before.

Frank Lee 07-03-2019 01:41 AM

If an extreme P&G short fill counts, I could be in with .38 more mpgs!

Yeah, back in 2014, but that one has always had an asterisk in my mind because it was a short tank. I want a full 10-11 gallon tank.

Okay, that'll count too. a full tank gets a picture of the hat, and a single run gets the below picture of a bumper sticker. Both are exclusive! Get the Ford into the 70 mpg club!

Do miles flat towed behind another vehicle count? :thumbup:

funkhoss 07-03-2019 06:54 PM

I just updated my fuel log.

Do I qualify? :D

Yessir. And you have not failed to get a 70+ mpg tank since December! Also you are at like 149% of EPA. Pretty amazing. My best tank was probably 130%.

You guys are driving on clouds or something??
I can't even hit 50 mpg on my 1.3 mt yaris

:) yes clouds... or "propulsion farts" to be technical.

It's mostly just radical hypermiling. I reset my trip MPG gauge last week to clock my new effort at 70+ and have been as high as 75 since. At 70.1 right now. The mods are to make it easier while driving more "normally" ... have you modified your Yaris much? Which Yaris chassis do you have? Manual transmission?

jimhs 07-05-2019 02:59 PM

Hi,
It is a 2007 yaris hatchback 1.3 manual transmission
Tires are pumped to 45psi and half of the top grille is blocked.
Last tank returned 47mpg (us) 80% country roads and 20% city

19bonestock88 07-05-2019 03:06 PM

I could try but I don’t see me *ever* getting a 70mpg tank... a single run, maybe... pic of UG count?

Ecky 07-06-2019 11:00 AM

I'll do my best. I have weeks or months of tuning ahead of me before I can dream of another 70mpg tank.

Do you do the engine off coasting technique? Pulse & glide?

The 70 MPG CLUB has an "SRA class" ("Single Run Average"), for which you get a picture of the bumper sticker! :) Pic of gauge readout encouraged but optional. Honor system!

The meaning of "single run average" at the heart of the 70 MPG CLUB's "SRA Class" is very flexible... if the run feels like an accomplishment, then it is. Haha. Test out techniques and see what you get.

I have a 28mi trip on which I can usually average in the mid sixties with diligent hypermiling, maybe I run the tires up to 75psi (theyíre about trashed anyway lol), remove the seats and go for the record?

Go for it. I am finishing some work on the car this month. Should finally have my wheel well skirts fully attached today. The driver side is on now. They'll be better and look cleaner than ever.

jimhs 07-06-2019 06:26 PM

@California98civic

I do eoc and p&g,but moderately, approx 10% of my most common 40 mile roundtrip commute.

Well that's the secret as to why you're not breaking 50 MPG. Good and frequent use of that technique is the way to get a car such as a Yaris up closer to about 60 MPG on a tank average. and there certainly would be trips that you could do that would get better than 70 MPG.

slowmover 07-06-2019 10:22 PM

Nice as a stunt.

Now, let’s load the vehicle according to design and see how things go.

The wusses can use the GVWR as limit, and the hairy-chested can use the axle/tire/wheel limits.

Ton Miles Per Gallon

as that’s a valid concept.

Shuffling an individual around bereft of gear or goods lacks meaning. Just “means” he does it with the air conditioning a motorcycle lacks. But he can’t account for unused capacity re empty seats and cargo space. IOW, it’s no test.

Make the test[s] real.

Vehicle scaled weight against published shipping weight (curb weight) for any test.

Loaded to limit, is the real FE test.

66-75% capacity for regular driving as the baseline.

I'm taking a 4x8 utility trailer full of crap down to southern Vermont tomorrow. I bet I still get significantlybetter economy than your truck, despite being loaded infinitely higher than the car is rated for.

It's a great idea ... let's create a category & run a competition. Seems to me Ecomodding trucks along the lines of Ton Miles Per Gallon would be brilliant.

teoman 07-07-2019 05:20 AM

That is a hair above 4l/100km. (4.035)

My car is rated for 3.7 l/100km highway.

Best i could do on the highway was 4.3.
Best tank 5l/100km

I should be able to get 70mpg on the highway. No way in the city (atleast my city)

Maybe I should have specified U.S. gallons. I think you may have miscalculated the US MPG's equivalent to liters per 100 km. I think 70 MPG (US) is equal to about 3.4 L/100 km. Are you maybe thinking of English gallons?

Nonetheless, if you want to make it 70 MPG in UK gallons because that's what you use, then go ahead. You still win the picture!

Slowmover, above, seems to be interested in a standardized test, and seems to think that that's the only serious test. But this is really just a challenge for individuals and not a test. An individualized instead of standardized challenge means that whatever your personal baseline has been becomes the legitimate context for determining success.

teoman 07-07-2019 12:40 PM

We use l/100km over here.

Taxi drivers and such use pennies/km. Which makes no sense as fuel is highly dependent on the USD and our pennies (kurus) varies a lot. So what you measure today is meaningless tomorrow.

On a road trip i just might be able to average that. But it will be hard, and very slow.

My submission for the 70MPG challenge (SRA class)
 
3 Attachment(s)
I wanted to try and see how well I could do on the trip from the grocery store (Walmart in Sutton, WV) to my apartment (in Glenville WV), but last time I hypermiled the route I only averaged 67.xxMPG... I checked tire pressure at the gas station next to Walmart, they all were really low, so I ran them up to 60psi (tires are wasted anyway and I really wanted to succeed, I normally do 55), and set off... I note the trip as three legs, Sutton to Heaters on WV-4, Heaters to Burnsville on WV-5, and Burnsville to Glenville on WV-5, for 28mi in total... I set personal bests on every leg of the trip and totally smashed my goal of 70mpg at the end...

Leg 1 ended at 99.5mpg avg
Leg 2 ended at 92.2mpg avg
Trip ended in Glenville at a total average of 77.4mpg!

Car was loaded with myself and GF, and a weeks worth of groceries so it kinda fit Slowmovers criteria of the car being loaded for the test lol

mpg_numbers_guy 07-08-2019 01:36 AM

Wow! Absolutely amazing! You have officially CRUSHED anything I could've ever done in the Civic, even with it's smaller engine and whatnot! Heck, many Insight owners would be enthused to get that kind of mileage! Awesome job!

19bonestock88 07-08-2019 02:29 AM

Thanks man, really it’s just pulse and glide and reducing aero drag and rolling resistance wherever possible... engine size doesn’t seem to matter much?

jcp123 07-08-2019 02:55 AM

70? Ha. Not with the amount of freeway I gotta do. Even when I had a special commute which would have been GREAT for this, I was high-50s. *sigh*

Do I get to use my 18-wheeler for that? Because ton-mpg makes this thing look like a star, and I drive waaaaaaaaaaaaaaay more miles in this than in any car...:D

Is this at 50-40 mph pulse and eoc?

California98Civic 07-08-2019 02:07 PM

I'm after it! Just recorded a 62 mpg tank that averaged about 72 in the last 200 miles because I started hypermiling the car more aggressively. Probably would have been a 58 or 59 mpg tank. Just refilled, now I have my wheel well covers back, and this is gonna be my 70 mpg tank!

Leg 2 was 40-30 EOC

Leg 3 was 55-40 EOC and then some in town at the end...

Thanks for posting back.
How do you keep battery voltage up?
Mine drops to 12.3v if i eoc too much with the headlights on

mpg_numbers_guy 07-08-2019 04:19 PM

^ when I do EOC I bump start the car 90% of the time to avoid further 12V drain from engaging the starter. LED headlights cut headlight draw in half. I still see 12.3v every now and then, and sometimes 12.2v, but most of the time it never goes below 12.5v.

A deep cycle battery, either AGM, lithium or maybe a supercap setup, is in the works when my almost new 12V goes bad down the road.

19bonestock88 07-08-2019 05:18 PM

^ same. My FLA battery is fairly new and hasn’t had even the slightest issue starting the car, and I don’t consistently hypermile enough to cause a consistent battery drain... admittedly since I left my day job and am getting divorced again I’ve not always felt up to it lol

jimhs 07-08-2019 06:12 PM

Hi,LEDs are technically illegal in the uk
..
I was thinking adding a solar panel, to charge the battery just after I park the car, but they don't work during the night:D
