well with the added ethanol, would gas addatives help with better milage or would it actually hurt more?

My baby lovers E10. Never saw a change buying E10 in SE PA. Still getting 31.5-34 MPG local.

Automatics..... already have inefficiency engineered in. Can't do alot there.

Manuals.... I don't downshift to slow the box. Unlike a diesel, a gas engine can't defuel in to the same point that a diesel can. Coasting and brake pads are far cheaper over the long run.

Saw a good show yesterday on making fuel at home for $2.40 a gallon using a whiskey still, at a rate of 5 GPH.

yeah plenty of people say they get that kind of mileage. doesnt mean it's true. oh and adding mods doesnt guarrantee lower mpg , and having no mods doesnt add up to being able to get 41.5 mpg.

Does anyone know of a link on how to do this?

So what's your point? That saying can be said for anything. For all I know you might not even live in Cali or even own a Scion. You might only have a Geo Metro for all we know, but do you answer every post on this forum the way you did mine? No, you don't (even though many of your posts are thoughtless and only meant to flame), so stop being a hypocrite.

I noticed you didn't comment regarding my MPG calculation methods... is that because they are correct and that I go beyond what other people do to calculate their MPG? It basically sounds like you have nothing to say at all in this post. So go cover your head in the sand and keep on pretending to only hear what you want to hear. Some of us know how to drive a car to maximize mileage... you don't, so get over it.

this thread is still interesting...even if i was a little off about what we were talking about..

I think some of your points are valid, and some aren't. If your methodology uses the same conditions at all times (e.g., same pump, same time-of-day, same weather, etc.) some of this could enhance your mileage beyond reality. For example, what if you are using a gas pump that consistently delivers more gasoline than advertised? If you stay with the same pump every time, it'd be no wonder you got exceptional fuel economy readings.

Personally, I tank up at a variety of stations, times, and conditions. In other words, I fill 'er up when needed, wherever I am. I make only minor concessions based on price, since saving a nickel often ends up costing a dime (especially in these times of higher fuel costs).

Without prejudicing your anecdotal findings, see my post at https://www.scionlife.com/forums/viewtopic.php?t=119078 for an example of a well-documented fueling log, where I am putting my money where my mouth is.

In short, my manual '05 xB gets about 29.5 in mostly city driving (with lots of short 3mi trips) using regular gasoline and a mostly stock car. Do you have any plausible explanation as to how yours might be getting 12MPG more?

Wow, how come so many of these threads seem to devolve into a lot of angry arguments about MPG? Gets a little painful to wade through them so I apologize in advance if my questions were already covered in another post -- I did try searching. (If it was please post the thread. Thanks)

Why did gas companies stop posting what type of mix they use at the pump? (I’ve never really looked at anything but the price before; I’ll try to remember to look closer the next time I fill up. Got a full tank now so it’ll be awhile. ) Do any companies still do it? If there are mixes out there with more than 10% ethanol I would rather not use them now.

Anyway, from my own non scientific experiences, I pretty much agree with Tomas’s explanation for variety (or lack thereof) in regional fuel mixtures. Assuming that’s true, does anyone know a site that compares different companies on the local level? Or is that pretty much a pipe dream since it can very by the batch? In which case has anyone in the Los Angeles area done the trial & error thing? Any recommendations?

I'll stay away from the mileage controversy, except to say that the first tank of dealer supplied gas came out at 30.4 mpg with mixed city and freeway driving.

Definitely expect lower mileage from winter blend or E-10, for a couple of reasons.

1 Ethanol has fewer btu's per gallon than gasoline by a wide margin. Less energy in a full tank means it'll get used up faster doing the same amount of work.

2 Ethanol has excellent anti-knock properties, so manufacturers can blend really crappy low energy gasoline with ethanol and still get the octane rating shown on the pump- again, lower energy in each gallon.

This is offset slightly by the fact that ethanol gives up free oxygen as part of the combustion process, giving a cleaner and more complete burn to the gasoline component of the fuel mixture... oxygenated fuel...

Part of the reason our little boxes perform as well as they do is the high compression engine- 10.5:1. The Owners' Manual calls for 87 octane, which is midgrade around here. Sure, it'll run on 85 octane regular, but that's only because the computer and knock sensor back off on the ignition timing, which means poorer performance and reduced mileage...

And so far as different brands are concerned, it's hard to tell, given the cross marketing agreements so prevalent in the industry, where different refineries can supply their gas to a variety of branded outlets, and that can vary from one load to the next . Modern oil companies' competition at the refinery and pump level is, uhh, marginal at best....

At least with ethanol blended gas, you'll never have to add gas line antifreeze...

And you're helping poor starving companies like ConAgra and Cargill stay in business...

I seriously want to know what the hell you guys do to get 40+ mpg in your whips. Mine is CONSTANTLY at 26-28 mpg with varying driving conditions. Even a complete highway run (non-stop on one tank), and I STILL saw no better or no worse than 27 MPG.

Velheru

One thing that those instructions didnt tell you is that when you fill up, let the pump fill and auto kick off. Dont try to "top it off" as you dont actually know how much you are over filling and will make the calculations inaccuarate

Subcompact Culture

Here in WI, all our unleaded contains ethanol. I know our 87 octane is 10%. I consistantly get 31-32 mpg. Last tank I got just a hair over 32 mpg. However, when I fill up somewhere that doesn't have e10, I get better milage. Best milage I've had was 38 on non e10. Best with was 33.

Ethereal_Dragon

ALL we have around here is E10... I don't even check anymore, cause EVERY gas station I have been to in the Chicago suburbs uses E10... And our LOW grade is 87 octane.. mid is 89, and high is 92... I THINK...

All I have to say is that I am pretty hard on my box, and I regularly get 30+ mpg... I fill up ONLY on Sunday's, cause
1. thats my only day off
2. to see how far I can go on a tank

I have NEVER had to put more than 9.5 gallons in. I got 311.9 miles on 9.4 gallons my last fill up. That is all city driving too...

I can agree with ApostolicFire with the getting 40 mpg... Not sure if anyone noticed, but it was goin 60-65... HONESTLY, how many of you flaming on him drive that speed on the highway?? I know I don't. The close-ratio trans doesn't exactly HELP fuel exonomy on the highway when your going 80-85 as MOST do. When I am at 80-85, the engine is running at 4000-4500 RPM... Going 60-65 I think it is closer to 2000-2500... I will have to check on my way home from work today.

EDIT: OK, on my way home, I found out I was incorrect by quite a lot... 60mph is 3000RPM ON THE DOT... 65 is about 3200-3400... Couldn't get to 80 cause of traffic...
