gas milage increase tricks

[cheezhead1952]

good day!

 

i've been reading a lot of chatter lateley about 2-3 ounces of acetone per 10 gals of pump gas giving anywhere from 3-4 mpgs, to 5 + ,phs per gallon claimed.. is there anything to it? or is it like the old fable of moth balls in the tank and the tooth fairy????

thanks

I gained up to 5 mpg and up to 10 extra hp by installing my billet grille! At least that's what the manufacturer says.

 

I'm going to put some "racing" air in my tires next! They say I'll pick up two tenths in the quarter mile!

Dude, tried the racing air, didnt work. What you really need to do is put some airplane propeller grease on the front of your truck to cut down on wind resistance. That'll shave off a good second in the quarter easily!!

well isnt that assuming that i would be getting 14 mpg when u dont even know what engine i have teh the truck so dont assume. K&N says up to 2-3 mpg increase FLOWMASTER also said that their exhaust system will make the truck gain horse power and fuel efficency so in my case i gained up to 7 mpg i did the math so just dont critizize shi7 when u havent even tried it.

WOW, I was thinking of getting one of those billet grills...Now I'm DEFINITELY going to get one.

Currently I only have the K&N Intake on my '06 Z-71CrewCab 5.3. I think what some may be getting a bit carried away on is the "Instant" fuel mileage through the digital display. When I first put my intake on, I went out on the highway and at 70mph I reset the fuel mileage. It went straight to 24-25mpg for about 2-3 miles, then started to come down over the next 3-4 miles. So for the first say 10 miles I averaged about 23mpg according to the computer. Now when I took the exit, turned around and went back, it dropped to around 18. Overall, I average 17+/- w/ most of my driving back country roads w/ mixed highway/city at 60mph. And that is w/ a VERY tentative right foot.

Good one guys i guess u guys just cant face the facts these companys have a dyno test on almost every product they sell why do a dyno test if they arent using it to sell there product they are the facts gm tbi units are very touchy to air and fuel the stock airflow of the tbi unit is 400cfm so any increase in air will affect the engine and when gain some more hp

But if you notice on thier specs, the usually say a gain "UP TO" such and such horsepower, which means from 0 to whatever number they put there. And as for on a dyno, you can get great figures, but when you get on the road with the wind resistance and everything else, then stuff changes.

i have gained up to 7mpg with a flowmaster force2 cat back and k&n air intake system its costly in the beginning but worth it in the end

Thats a 50% increase in mileage, do you have any bridges for sale?

He meant to say "I gained up to 7 dB..."

This thread has gotten very funny. Someone here has got to know how much more power must be created to yeild an increase in efficiency noting all other factors are the same.

Acetone will not do it, but dimethyl ketone will.

Acetone is dimethyl-ketone and it is not a silver bullet either.

I know, I just wanted to see if anybody would catch it. Acetone is also known as 2-propanone by the IUPAC classification. I would not try anything like that in my gas tank.

I am in the market for an intake and an exhaust, but I am skeptical of what the manufacturers say I will gain and what I will actually gain in power. I have been researching for some time now and I can't find any side-by-side comparisons of exhaust systems, headers, or intakes. This fact alone tells me that none of them actually live up to the hype touted by their manufacturers. Another reason to be skeptical is simply, If you can open up so much more horsepower by simply adding a more free flow intake and a better exhaust, then why doesn't the truck just come equiped with better parts stock? Aftermarket parts may add a minimal amount of power, but not as much as they are claimed to, and certainly not enough to justify their price tag. If anyone knows of a site that has comparison of brands, please let me know.

That is very true the other reason they say that you will gain up to this amount of hp is because the engine makes diffrent horsepower at diffrent rpm's all cars and trucks are diffrent they dont come exactly the same from the factory but they do claim that you will gain up to that amount of horsepower at the stated rpm. As for the dyno i dont know of anything else as of wind resistance that would effect the truck enough to notice a big power decrease from dynamometer to the road

Not to mention what it can do to some of your seals and hoses too. It is nasty stuff.

There are plenty of test that have been done.  Is the K&N flowing more air, yes.  But is it stopping all of the dirt a paper filter would, NO.

 

Take a read of this :

Why was the K&N test done with fine dust and the others done with coarse dust? HMMMM....Kinda skewed test if you ask me. I've never had any problems with my K&N but then I clean it often. My truck does run better with the K&N system but it is loud.

Good paint thinner and degreaser though.

No arguement there and good paint remover too with some types of paint.

go out and buy a intake and exhaust if u want to save money
