I saw on the news about a gas additive which improved gas milage and carbon dioxcide release.

Does anyone here have any comments on these type products. How does this affect the engine/transmission for prolonged use?

Right now I am happy with my milage but I think that in the future I will like to try(or need) a product simular to what was presented.

What experience have any of you had using these products. Are they highly recommnded?

Also does anyone know about the octanes available when you purchase gas at the store? Like I get confused about the 3 choices offered and I have heard not to get the highest number-however why is it available if it is a bad thing?

 

the octane rating is the m+s\2 method
it's only menas the fuel's ability to resist detonation
the higher the # the better it is at resisting detonation
don't buy a higher octane gas if your car does not need it
it's useless proly won't do any harm either
i need to use 91 premium because my 5th gen prelude has 10.6:1 compression too high for even 89 octane

 

Do not use any gas additives. They don't help anything, with few exceptions that you don't even have to worry about.

 

they help clogged injectors and fuel filters. i say use jet fuel.

 

The only injector cleaner that actually does something is the Chevron techron additive. It also happens to be the only additive approved by Mazda for use in their cars.

 

LOL! The closest thing to jet fuel that you can easily find, is kerosene. Fill up your car with that & let us know how it works!

 

Believe it or not, kerosene is a main ingredient of some fuel injector cleaners.
