Does adding octane boost bought at a gas pump actually give better milage, every time?

Question

How can you tell which octane boost is best and how should you use that liquid?

Answer 1

I disagree with the other answers. My Opinion on Octane Boosters, and I've tried many Products put to the test. True a cars tuning should be to specs. But over the years I found Adding a Bottle of OCTANE BOOST to a full tank of gas, one thats going to boost your octane 5-7points, will in fact improve mileage, now I have Argued this topic with plenty of assosiates, and in the end they all come to understand that what I'm saying is true, IT DOES work. Fuels today seem to be improving on the market with added substitutes to improve mileage. and also to Improve on the cutting down the pollution and creating enviromentally friendly fossil fuels. I dont think fossil fuels will be much friendlier but we can try to make it friendlier by keeping cars tuned up to keep the emmisions of the by products of the engine down low. You see adding a higher octane now and then will improve the life inside the engine and minimize the risk of carbon build up around the intake/exaust valves, burning off the carbon build up that may generate on top of the pistons.plus the higher octane also cleans the fuel line carburetter jets/ fuel injecters etc... to help keep the engine running at its specified specs like the day it came out of the shop is possible. Regular oil changes are a must, as well as changing the air filter, If you live in the city change it every six months. I swear if you use Octane boosters it does improve the sustaining of horsepower and will in the long run generate more mileage for you. Also you'll have less pits stops to the garage for tue ups or a mates place having to do a heart transplant to your vechile. I hope this helps you understand the in's and out's of the engine. It's the heart of the vechile so look after it as you would your own heart.

Answer 2

No.

Octane boost is for performance cars that require more octane.

If your car is designed to use 87 octane, you WILL NOT get more power or more fuel mileage from using octane boost or ANY fuel additive of any kind.

Period. End of story.

Check your owners manual. Use the octane your car is designed to use. If it is supposed to use 92, don't use 87. If it is supposed to use 87 don't use 92.

Using higher octane or adding octane boost is like wearing shoes 2 sizes too big and thinking they will make you run faster. That just isn't how it works.

If you want to get better mileage, check your tire pressure. Coast up to stop lights, take off slow and steady and drive the speed limit. :-)

Answer 3

There is a pretty minute effect but it's generally not worth buying high octane gasoline for the increased mileage.
You should run the grade specified by the automaker, or if it is an old car and you have problems with the engine running on after turning off the ignition, or if the engine pings while driving then you need higher octane.

It is a myth that you should by high octane gasoline for the mileage.

Answer 4

octane rating is a very misinformed topic

the higher the octane rating the slower the fuel burns.

by running higher octane/race gas
you do not gain HP
your car does not go faster
and you do not gain miliage.

octane requirements are determinded by the Physical requirements of your specific engine and its specific tune.

example 1

a race engine with a high compression or TC/SC is going to have a very high cylinder pressure because of this it will require a relatively slow burning fuel in order to maintain a controlled ignition event.

example 2

a N/A rotary motor with low compression will by nature have a very slow ignition event in which case a faster burning fuel/lower octane rating will benifit this engine by producing a faster/more powerful combustion.

You seem to be voicing a illigitement theory, the facts are this; octane is simply a fuels resistince to ignition or slower to burn By using a high octane fuel in a low compression engine with a weak ignition system for example you will actually lose efficiency which will lead to loss of economy and and over time will end up creating an increase in carbon buildup. The key to both Hp and economy is to run the hottest or lowest octane fuel possible while retaining a controllable ignition event there is no benefit by using a higher octane when not required . This is why not all manufacturers reccomend premium. there some cars (high performance SC/TC) that I would reccomend higher octane than the standard premium but it is complety dependent on the specific vehicle.

Answer 5

More octane will not increase mileage. Octane boost will only prevent "knock" in engines that have higher compression ratios. If you are not driving a high performance car, don't bother with octane boosters.

Answer 6

Unless you have the most highest end of cars, the extra octane you pay for at the pump does NOTHING ! ABSOLUTELY NOTHING ! You do not get better gas mileage, you do not get more power.

Answer 7

i've got examine a pair of surveys on that concern and the outcomes have been you will possibly get greater beneficial mileage with a/c off driving around city besides the shown fact that it did not incredibly say how lots. With the cost of gas you need to to top off and write mileage down and run each week or so with a/c off and do same with a/c on and evaluate mpg. The survey did tutor there wasn't lots differance at highway speeds because of the fact the homestead windows down interfered with the areodynamics of the automobile.

Answer 8

It does not do anything expect waste your money.
