Improve gas mileage by using octane booster?

my friend bought a bottle of octane booster, it cost him like $3.80. So since its like 80 cents more then a gallon of gas, wouldn't it help by buying a bottle of that and putting it in with ur fill up and u'll get mpg equal to that of 2 gallons or more?

idk i think i'm gonna try that. You get more performance and supposedly better gas mileage. But idk what that will do in terms of engine wear. I started using 87 octane gas so who knows

well one of those bottles isnt anywhere close to a gallon.

eh I think octane boosters don't help at all, I tried using those in a Honda accord I had with a CAI and it did nothing but waste my gas faster, no I wasn't gunning the motor down either. Since I put my CAI on my 04 S recently my mpg went up by 3-4 mpg, I use 91 octane from Shell

Rollas are made to run on crap gas. Anything higher than 87 is a waste of money, unless you have to worry about detonation.

Be cheaper to put in higher octane gas than ocatane boosters. If you have a higher mileage car or one that has significant amount of carbon built up in the engine - you might get better gas mileage with higher octane gas. Otherwise - if your car is a good tune, low miles, and pretty clean on the inside - just a waste of money.

Note how the octane booster boost the octane rating - does it mention increasing the number of octane "points" or increasing octane "number'. Reason - one octane "number = to 10 octane "points". So if the booster is supposed to add to a full tank of regular gas and boost octane by say 10 points = then your 87 octane would be 88 octane. Would have been cheaper to spen the extra 10 cents per gallon to get 89 octane. Also - most octane boosters are parabolic compounds - that means that at a certain point - adding more booster will result in no net change in octane. Depending on the blend of gasoline and the amount and type of aromatics used to boost the native octane - adding a booster may be ineffective. ie. if added to 87, may add 10-20 points - added to 89, may add 5-10 points - added to 93, may add only 0-5 points.

well but that doesn't man I'm gonna make my car run on crap gas hehehe, I like to take care of my car and it even gets Mobil 1 synthetic oil every 2700 miles, yes call me whatever you want, my car deserves the best if I want it to last a good while without problems

i thought it would improve gas mileage, and i meant like u add one bottle and that equals to like 2 gallons of gas, or so i thought guess not

I think you are misreading the bottle or something

to me octane boosters are just a rip off, best way to improve gas mileage or keep it good is by oil changes, air filters and regular maintenance and tire pressure plays a huge part too.... oh and the 5 tons of crap on ur trunk or back seat too hehehe

it dosnt do shit on my car, ive tried it a couple times

...wow...2700 miles? Talk about throwing money down the drain D. I run non-synthetic oil...and using BG Motor Oil Additive...my oil is still pretty clean at 5,000 mile.

You don't need to be changing that often.

You're not doing your car any favors by running 91/93 octane..

My old rolla has 182k on it -- it's still getting fed 87 octane..runs beautifully.

well I do drive my car pretty hard and not as in guning it but as in lots of miles, I bought it back in january with 29,900 and now I have about 36k on it, I drive a lot.

all i know is my car's mpg is unusually low of 14mpg... 18 if im lucky... idk... i dont gun it as much as i used to... what could be wrong?

18 mpg? wtf dude, u romp on that gas every corner or what? lol

I got a similar situation. I don't think I've ever gotten higher than 26 mpg, about 60% of that city driving and LOTS of coasting. Average about 22-24, sometimes as low as 18 if I let it idle. But there's loads of traffic where I live, even the quiet one-lane country roads are now packed from 7am to 7pm.

octane boosters do not work.

They will put a fine powder in your combustion chamber...less bang...less power...more money.

All of these things are "snake oil" remedies (ask your grandparents)

i dont... a full tank only lasts me a week and i usually fill it up around 10 gallons at a time... (full tank) and i only get 160 miles a tank...

wow dude that sucks, I get almost 400 miles to the tank, how come ur car is getting so low mpg?

Yes I run Vpower from Shell, only fuel I use.

I'll try midgrade then, eh not like I really care, the car just runs pretty smooth on 91

Ok...you have a problem.

My 4.7L Iforce V8, in a gross weight 6300 lbs truck gets 18 and about 390 miles to 21.4 gallons of gas.

On the subject of gas, I prefer to run Shell simply because of it's effect on my bike, when I can afford I'll use premium, simply because I seem to have a tendancy to lose a little more than a mile per gallon on anything else.

Now in the bike it's a different story. The only thing that goes in there is BP or Shell V-Power. More often than not Shell V-power...but always 91 octane minimum. (Even BP I'd rather not use, anything but Shell really dogs the bike down bad.)
