Fuel Economy

[marcus]

FOUND OUT! something...its quite interesting as well...

1/5000 (1 part acetone 5000 part fuel ) mixture will give you better fuel mileage up to about 27% gas savings. may be worth to try that doesnt sound much to mix with fuel..hmmmm interesting..

Acetone will certainly help your FE, at least at first. Then it goes downhill as your engine goes downhill because Acetone eats through just about any non-metal parts like gaskets, seals, hoses, tubes, etc.

It is not worth it, especially for any length of usage.

[marcus]

it does but i dont think it will do it on that mixture.. too small of an amount for it to do it.

How about we mix you a nice glass of ice water with 1:5000 lye, and then have you drink one glass of it every day?

Trace amount or not, some things just are not safe in any quantity.

[marcus]

nothing will happen then coz "lye" doesnt exist on my dictionary...lolz.... but i see what you mean.." dont drink acetone "...hehehhehahahaha

I wouldn't feel too bad to about 30 MPG around town. If commited to save on gas, anyone could simply drive less. If I take lots of 40 MPG two-minute trips while you make 30 MPG on longer commutes but bike or walk at other times, we might still be comparable in overall fuel usage.

Thanks for the response! Got the message. Makes very good sense to me. I am very impressed by your pragmatic, balanced, and down to earth attitude toward this subject. Also, I fully understand that hyermiling is a subject very different from basic day to day fuel economy. That is why I have edited the subject of Post #1 of this thread to "Fuel Economy in General". I regret that I have not been able to change the name of this thread accordingly. You know, I did use the word "practical" in Post #1223.

I am glad that the Yaris is a fuel economical car in its own right and almost everybody who pays attention to responsible driving can achieve a reasonably good level of F.E. with it.

Though inevitably a few (certainly not all) very exotic hypermiling techniques may give rise to some safety, legal, environmental, warranty and wear and tear concerns of a varying degree, I still think that it is good to know that such techniques exist. It is up to the good sense of individuals whether to try them. For me, I bought the Yaris for its good F.E., amongst other things such as comfort, flexibility, resale value, ease of driving/parking, and of course, reliability.

I am personally addicted to achieving good F.E. but will not give up comfort and relaxed driving to achieve the last little bit of fuel saving.

For academic interest, I still try to know more about not only the easy/practical but also the advanced/exotic fuel saving techniques, though I for sure will not put every one of them to actual use.

Please post more here.

My friend, before you proceed, please note that this is a very controversial subject. Please read these threads for some reference:

I personally do not think the "saving" justifies the risk (or uncertainty, to say the least). However, I will always try to keep an open mind towards this kind of things. If you have further reference materials, please share them here.

This one is about acetone being a solvent, especially of plastic materials:

34.6MPG mostly city.

BTW - I tried the acetone thing in my Tacoma. It just plain didn't work. I used it on a 1000 mile trip. On the first half I didn't use it on the second half I did. MPGs were pretty much the same. 19MPG HWY. Pitiful actually!

[marcus]

yah i wouldnt try acetone either..but it might come handy during emmision testing..

Well, all, my hypermiling efforts have finally led me to reach my goal of achieving 50 MPG with the Yaris!

I fueled up today with 10.383 gallons after 540.9 miles.

That is 52.095 MPG.




The miles represent 4 commutes over the mountain to work, letting the wife run errands twice, running my own errands twice, taking the parents out to dinner, one trip over Donner Pass (9,300ft.) to Sacramento (sea level) (230 miles round trip) and a lot of running around inside Sacramento.

Never forget that in order to roll down a hill you must first use lots of fuel to climb it, or you must climb it once you've gone down it. There's no such thing as all downhill in a mountainous region.

id say its almost a figure of speech...high km run =downhill..but im sure that was not the case...
