anything less than 93 octane?

So if I started running 87 or 89 in my truck it would run lean and ping right? I run 93 in it right now and I'm thinking of starting to use that shell V-Power with nitrogen in it, but I'm skeptical about it.

Not necessarily run lean, but the fuel would start combusting before your pistons reach TDC....that's where the pinging comes from. If you have an 04 your truck does not have a knock sensor that would back off the ignition timing to prevent it.

I'm just gonna keep running 93 or 91. Would hate to be cheap and eff up my truck.

Lots of members run the nitrogen stuff in their trucks with no negative results. I run it in my DD and Have had no problems.
 
I haven't found any referance to this increasing octane ( I may be blind). Will it help me run my 93 tune on 91 or 90 octane fuel if I do 3 oz per tank?

I found this article which was written last year. http://www.brightgreen.us/lubedev/smartgas/additive.htm

Just picked up some acetone at Autozone from Klean-Strip. Looked at their website to confirm that it is 100%. I have about 9-10 gallons left in the tank so gonna put 2 oz in and see what happens on my 35 mile drive to work and 35 miles back.

Hope I'm not jackin this thread but it seems the topics seem to be parallel in nature.

The guy who wrote this article is at best misinformed and at worst is a complete idiot.

He freely mixes terminology and concepts that are unrelated and gets them wrong and then throws in big business conspiracy to try to lure the reader into thinking he has some sort of credibility. What a wack job.

"Great mileage takes work and the cooperation of a good open-minded mechanic in your area. Preferably an older mechanic who remembers what it was like to work on real cars before the Judas computers that deliberately kill our mileage on new cars."



​
Judas computers? Bwaaaahahahahaha! What a jerk-off.

"Because acetone burns so slowly, it can in tiny amounts raise the octane level of the gasoline. Your car's computer is no dummy. It may detect that the fuel is burning with insufficient flame velocity if you add too much acetone."





​
Gee, do you think if I should go to Dodge and tell them that my truck doesn't get good gas mileage and I think that they need to replace the flame velocity sensor? He mixes the concepts of fuel burn rate as equivalent with octane rating. These are not the same concept whatsoever.

Acetone is a strong solvent in the ketone family and Xylene is an aromatic hydrocarbon. So in plain English, the first one makes a good carburetor or fuel injection cleaner and the second is an octane booster (Xylene has around a 117 octane rating). The benefits these people are seeing is likely due to getting their old vehicles back up to OEM specs by doing maintenance and cleaning up their fuel systems, etc. However, the concept of using a solvent to assist with gasoline vaporization could have some merits. This might actually work to some degree but I doubt it would be much. It couldn't hurt to try though. Our trucks don't get bad mileage because they are craving acetone, they get bad mileage because they have 500+ cubic inch motors....

One thing is for sure, do not spill acetone down the side of your truck. It will remove the paint if left on there for any significant time.

Let us know if you see any benefits.

My wife is in charge of R&D for Chemical Manufacturing Corporation she is a Ph.D. chemist. When I asked her about acetone her response was much the same as yours. Her company manufactures a lot of commonly known products and component chemicals for companies like Proctor and Gamble, NASA, BASF and many others.

Her specific comment about acetone as a fuel additive and its impact on fuel mileage was that the biggest opportunity for improvement was the mental attitude of the person putting the acetone in the tank. If they hope it will work it will, if they are skeptical it probably won't. So in her opinion it is the driver using the acetone that makes the difference.

You may be on to something: we could maybe put a book or audio cassette series together. We could title it Willing your way to great gas mileage and a greener Earth. It would be a form of Zen mechanics. We could sell beads that people could hold over their motor and pray that their mileage improves while chanting. This could be the next big thing!
 
So the people on the site who have documented gains and professional race teams over the last 40-50 years are just using Zen?

Show me some documentation. There are only anecdotal references. No documentation using anything even remotely close to controlled conditions, and certainly no one that has been able to recreate the results using the same controlled conditions.

Its just rumors and wistful thinking, in my opinion.

With the issues we have nationally with consumption of foreign oil, I think there would be a major effort in this direction if there was a shred of evidence to support the rumors. Lets just call it urban legion and let it reside with the guy with the hook that gets left in door handles on lovers lanes.

93 octane or less

I have run 89 and 87 in mine but I detuned my VEC 3 for it as I had program cards for those octanes. (I got lost in the middle of Illinois and all I could get was 87). It ran fine. I dont know how well ti would work without the downtuning. I'd be worried it would detonate.

has anyone dared to put, or accidentally put any gas with octane less than 93 in their truck? what are the affects if any to the engine?

Basically, yes. I don't believe that race teams use 1 - 2 oz of acetone to increase their fuel mileage. That's just nonsense. They may use acetone for its volatility or solvent properties, so that the fuel system stays clean and the injectors keep a consistent spray pattern throughout the race. The reason that race motors don't get good mileage has everything to do with the rediculous cam timing, extreme rpm, and the need to have high power to weight ratios and nothing to do with 1-2 oz of acetone.

The people that have documented gains seem to be doing very small sample sizes (5 mile runs, etc), which violates standard scientific method, and proves nothing. If I run my truck on a slight down grade for 10 miles, or go with the wind for 10 miles I bet I can show a 10-15% increase in mileage.

Now, that stripe of missing paint below the gas cap, that may have something to do with acetone....
