Re: Boost gas mileage 15-35%

My third tank has just done identical mpg to my average. Some snow, but long trips in this tank. My conclusion so far is that acetone does nothing at all for mileage.

Re: Boost gas mileage 15-35%

Year: 1986Make:
Model: Chevy
Engine: k5 blazer
Fuel:93 octane
Mods: 406ci high performance engine with only 500 miles, 35in tires, 9in lift, dont forget the 2500 stall...
Driving type/styleaily driver
Before average mileage: TBD (for sure under 10mpg)
After average mileage:TBD

I just got my truck done and didtn think about how much gas was going to be untill I started to drive it. Jesus I should have built a 305ci or something...Anyway...
I just filled up and will take my MPG on just gas alone. Then try it with acetone. I will let you know...
Even if it does not improve MPG at least my engine will be clean as hell...

Does anyone know if BP stations have alcohol in thier 93octane stuff?

Re: Boost gas mileage 15-35%

It depends on the area. Northern Ohio does.

Re: Boost gas mileage 15-35%

Well MPG is roughly 6mpg. Now for the acetone. I put it in last night and drove for a while, coldnt tell much of a difference. I will let you know later if I see improvements or problems

Re: Boost gas mileage 15-35%

That is very bad mpg, it is bound to come up whether you use acetone or not. I think that is the problem with stuff like this anyways.

Stangbuster, nothing personal at all, but would like to take your truck for an example and even thought the circumstance may not be yours at all it does illistrate the point. Next post.

Re: Boost gas mileage 15-35%

k-5 with new 406 engine 500 miles and first tank or 2 gets 6 mpg.

2nd tank gets 7, 3rd tank gets 8, ect. mileage settles at 9 mpg and we all think that it is from the acetone, I'll pick on myself now. next post

Re: Boost gas mileage 15-35%

Here I come with a blazer that has averaged 18.5 for a number of years and just happen to be getting 16-17 for the last few monts (do not know why)

I here about acetone and try it and lo and behold after the 3-4 tank the mileage comes up to 18.5. Am I to conclude that it is the acetone? haha

Re: Boost gas mileage 15-35%

So your saying that new engines dont show their true MPG untill they have been in use for a while? If it makes a difference, I have changed the oil 4 times in the last 500miles. MOBIL 1 synthetic and fram filter.
Yea that is horrible mileage. Well, I had it built to make power and it takes lots of gas to make lots of power. I get what I paid for I guess...

How do I post pics on here? PM me PLEASE!!!

Re: Boost gas mileage 15-35%

BTW I still cant tell a difference with 1/2 tank gone. Maby it does not affect high performance applications because they are already making such high hp/tq numbers in the first place.?.?.?

In your application stated, I would think the acetone made a difference by cleaning carbon deposits out. I was wondering what year and model your blazer is.
I have a 93 s10 blazer(4.3L) that gets bad MPG also. I always end up ruining O2 sensors when using SeaFoam(the best) and other claimed engine cleaners for some reason. I think as it cleans out the motor the deposits coming out the exhaust collect on the sensor making it read lean, in turn dumping more fuel into the motor, then eventually it will start boggin down on the highway and running like shit. I have tested this numerous times over the past 5 years during my ownership of two seprate yet identical 93 s10 blazers. That is why I am weary of trying it in a FI vehicle like my 93 s10.

That is not really my point (although I would say that the mpg will continue to come up a bit) Your mpg is really irrelevent whether it is good or bad. The point I was making was this,,,

It would be wrong to conclude that acetone (or anything else) is causing a mpg variation until the variables have been eliminated and a true baseline mpg has been established and a nice repeatability can be had.

I had already established a baseline because of prior testing and know what my low and high mpg is. It varies, but for the most part you could remove my fuel gage and I could guess the gallons to fill tank within 1 gallon very easily. It is that repeatable.

If I had started my acetone testing during a 19 mpg "season" and lo and behold I use acetone and my mileage happens to start dropping to 17 (like it will normally) then it would also be wrong for me to conclude that the acetone reduced the mpg.

My bazy is a 95 LT 4 dr with 175,000. I have owned it for 100,000 and have tested nearly every tank of fuel for mpg (I do on all my vehicles, I know I'm a freak) I thight mine did exactly what the sticker showed. 18 and 23 hiway

Re: Boost gas mileage 15-35%

Ok I see what your saying now. Btw I just changed another variable, because I got different tires. The boggers were way too agressive tire for how much im on pavement. I think it auctually has less load on the engine without them. It looks like I will have to start my test over or do it backwards.
ABOUT POSTING PICS? <------Someone Help!!!

Re: Boost gas mileage 15-35%

My 4th tank update is again one of my lowest recorded mpg. It is at 15.71 and 1-2 below my average. I am done testing with ethanol fuel and filled up with 90 octane clear gas and still added the acetone for now to see if it does any better on the clear gas. I believe it to be a complete waste of time and money, ok maybe learned something new,,,

My vote so far for ethanol gas would have to be from 0 to 10% LESS mpg, but is probably right on 0 % realistically as I cannot blame a reduction on the addition of acetone. hoax so far.
