Here is what I'm talking about if you don't know already:
http://pesn.com/2005/03/17/6900069_Acetone/

I'm planning on doing this after I figure out my stock mpg. I've got a 91 crx dx auto, and I just got around 40 mpg so I'm going to make sure I get enough miles to average and then compare, once I get the money I'll swap to an hf tranny so yeah, I'll be at the junkyard tomorrow looking for that stuff. Anywho, anyone tried this? Anybody got some opinions on this?

i doubt it makes enough of a difference to offset the cost of the acetone, but try it.

man that **** is cheap and i don't know where you live but the gas here just went up to 2.92 a gallon so if it gave me an increase of just 10% it would give me an extra 3 miles pre gallon and the artcle said 15-35%. not only that but if it does work like it says then it will also help your engine in the long run.

i have a 89 hf tranny if you are interested email me speedracer84@msn.com , my pm on here doesn't work well.

there is a reason they use acetone in paint thinner.. and have you ever gotten it on anything plastic or rubber? incidentaly your fuel lines are made of rubber.. and guess what.. acetone eats rubber. thats right eats. probably a bad idea. unless you have stainless steel fuel lines and metal fuel injectors.

go here. http://www.coleparmer.com/techinfo/chemcomp.asp

then choose natural rubber and acetone.. and see what the chart says.

for natural rubber: "Softening, loss of strength, swelling may occur. not recommended for continuous use."

for plastic: "Severe Effect, not recommended for ANY use."

cliffs notes: acetone would be in gasoline already if it were a magic mpg increaser.

probably NOT a good idea to put acetone in the tank. will damage hoses and possibly the O2 sensor.

No offense, but I don't think you read too closely the tests they did on this EXTREMELY diluted amount of acetone not doing crap when they stick all the plastic junk in there. In any case, there are plenty of things that are good and are not done for the sake of money. Would an oil company really want to give people the ability to buy 15% less gas just to be nice? They haven't expressed interest in that yet...That is like saying if you could build a 100 mpg car then they would be all over, but VW has been doing it for years and they won't even sell them in the US...

I would have to say not to do it.

We'll try this on my site once it's running. When we have 5 volunteers for a controlled study, we can do it.

Sounds like a deal. I would also point some of the doubters to the statistics from all the people who have tried it that are linked up on that first page. I'll look for the specific address for it now...

i guess i came off a bit harsh on my first post, but what i meant is that in countries where gas is quite a bit more expensive, i.e. the rest of the world, it would probably be added to the fuel already. there are chemical engineers that work for oil and gas companies that determine the proper mix of all the chemicals that will produce a clean burning fuel that will not react with internal engine components.
i agree that you would probably be using them in a very low concentration, and the result of which might have a very small impact on your fuel system, but it might not. you would probably get better results by spending $350 on a wideband o2 logger and a chipped ecu to lean out your mix across your entire rpm range. or you could buy a diesel car and convert it to burn used cooking oil.. then you would never have to buy gas again.

i respect the fact that you are trying to get higher mpg, dont get me wrong. ive done plenty of research into the topic as well. its great that adding acetone works, its just the why and how it works, as well as side effects involved are things not to be taken lightly. unless you have lots of money and spare cars lying around, which i personally dont.

SVOboy

I was going to grease it up before I went to honda, I just can't afford a clean diesel right now and going to college I will have no place to make the crap anyway. Once I'm out if I get a job I'll prolly try to import a lupo and run it grease, but we shall see how much that costs, haha. Anyway, my plans right now are to swap to a manual hf tranny and d15z1, so hopefully I can at least git in the 50s. But do you have any links to this o2 snesor business, i've not heard of it yet? No hard feelings, of course.

sanimalp

this is one of the few wideband tuners available http://www.jegs.com/cgi-bin/nc...r=361 i am sure you can find one cheaper like on ebay or something, but you use them to tune a car's air to fuel mix. usually if you turbo your car, you need one or atleast need to get tuned with a wideband, otherwise your car will run like ****.

what i was saying is that if you get one of those widebands, and then get your ecu chipped so you can program new fuel maps for it, then you can use the wideband to datalog your o2 readings and using those numbers you can adjust the fuel usage of your engine so that you are running lean (less fuel), but still safely lean. granted you already probably run a touch lean from the factory, but with a wideband you can get crazy and lean it out perfectly for your engine.

there are also places you could take your car, like performance shops, and tell them what you are trying to do, and for probably like $300 or $400 they could tune your car to run lean in all your rpm ranges. of course that is just for tuning time, they would have to chip your ecu to allow modifications which will probably cost extra.

and as always, the link for THE do-it-yourself engine tuner, http://www.pgmfi.org .

a free way to make your car get better gas mileage is to gut it. like take out all the interior plastic trim and seats etc. the more weight you lose, the less work your engine has to do to get that mass to 60 mph. and the best part, its free.

another way to get better gas mileage is to buy a vaccum/boost guage, and when you drive around, keep it at the zero point, where vaccum and boost are both evenly balanced. you can do that even without a turbo car, you just wont get much deflection in the guage itself. that just tells you the point where your engine is doing the least amount of work against itself. if its is creating a vaccum or creating boost pressure in your vaccum system, it causes the engine to work against itself. at the zero point it is in harmony. so if you take a long road trip and try to keep it at zero vaccum/boost, even if it is probably at 55 mph, you will get the best gas mileage out of your engine. i believe the equilibrium point for the d15 is somewhere around 2800 rpm.. so if you drive around there it will be about 0 vaccum/boost.

Don't forget, the z1 engine runs a wideband o2 sensor. My understanding is that the real benefit (in mileage) of the z1 comes with the ECU/o2 sensor combo. It's the only civic obd1 engine running a wideband o2 sensor. Odds are it is already leaning itself out based on this alone.

So swap in the z1 and the HF tranny and you'll be good to go. Hell, we can even have a contest to see who gets better gas mileage. By the time we're both done with our swaps gas will be around $3.50 a gallon.

ALL this just to save MAYBE $5 a tankfull. Perhaps a slightly better paying "mac" job would be even more efficient?

sanimalp

whoa. that is something i didnt know. that is cool. i wonder if you can chip that ecu, because it would make a great candidate for a boosted car, and much less drama than converting a narrowband ecu to wideband. ill have to look into that.

Firstly, it is a "mcjob." Secondly, it's not about being cheap, it is about petroleum indepence and blah blah blah environment, at least for me.

Bare, I understand that you don't want to build for fuel economy, and that's fine. you'll be the first in line when the new H3 comes out. You can afford gas. That's great. That's wonderful.

I actually work at home. my civic hasn't been driven in over two months. My Fiance's CRX has been filled up 3 times in 2 1/2 months. We don't drive that much.

I can afford gas.

But I still choose to build for fuel economy. Why? Well, first of all no one else is doing it, so the parts are cheap. Second of all, it's fun. why NOT build a car that saves you money? Why NOT build a car that can get 60+ mpg? With family and friends in far off locations, road trips are a must. Why not save money while making the trips? And while we're at it, why not reduce our dependance on foreign oil?

I figure with all of your boosting, adding turbo, and throwing in oversided injectors someone has to lower the average back down.

might as well be me, Mac.

SVOboy

Woot.

Check out the CBR injectors that everyone is throwing away with their ITB projects, they are a 270cc High impedence (I think they are High Imp anyway)....

Here is the trick reason for using them, they have a 4way spray pattern as opposed to the single that our stock injectors spray.

This means finer droplets, which evaporate more readily and thus burn more completely! A more eficient burn ='s more power and economy in one fell swoop.


I like the power/economy combo. I know I will never run with the big boys, but I can go faster longer!

This sounds like a good idea. Do you have any moe info? The CBR is the motorcycle, right? Do you have any idea what the stock injector size is for the Civic VX? Which CBR should I look to take the injectors from?

Anyone know where you can buy 100% acetone?

i just bought some at walmart and i'm sure you can get it at walgreens or cvs or whatever drugstore you have in the area.

Yup,

vegaskurt

Autozone in the paint area has acetone.

Which cbr has those 4 way injectors? the 600 or the 900?
