i dont push it that often but as for the gas my company pays for my gas couse of my communt to the delaware office from batlimore.

 

my last fillup i put 13.962 gals into my tank.... talk about pushin it to the edge

 

93 octane has less contaminants and is much cleaner for the fuel injectors. I've been using 93 in mine. Unrelated to that, I've been getting about 340 miles after using up just over 12 gallons which is about 27mpg and I'm always driving fast.

 

yeah, yeah, yeah use the gas you want. if my company filled my gas tank i might use a higher octane. i have always used the recommended octane for the engine and have never had any trouble with build up. i drove a saab 86' 900 turbo which could use 87-93 octane. it did run much better with the high octane but ran okay on the regular.

i might fill up with premium this week and see if i notice any performance difference.

will let you high test boys know....

peace.....

This issue has been gone over before-- In a car whose engine is rated to use standard 87 octane fuel you're simply throwing your money away if you use fuel of a higher grade. 87 octane fuel containing more contaminants? What?

Look, all octane does is retard fuel detonation-- It doesn't have anything to do with engine deposits or carbon build up. That's the job of fuel additives like Chevron's "Techron" and such. Octane in and of itself has nothing to do with ridding your engine of deposits that can often cause pre-ignition in the first place, and it won't make your car faster.

Unless you're having marked problems with engine knock/ping, you're flat out throwing your money away on fuel that will buy you neither better performance nor efficiency. It's as simple as that.

Why is it so many of you just don't get it? High octane fuel in small cars rated for standard 87 octane represents a wanton disregard for prudence in car ownership and operation. Wasteful, oblivious, ignorance. Impertinence to thoughtful logic couldn’t be better demonstrated.

Read all about it.

Note that a higher octane rating simply allows for more fuel to be shoved into the combustion chamber, thus allowing for a larger explosion and more power per stroke. It has NOTHING to do with the fuel itself containing any more energy than regular fuel does. Geeze. So unless you've cranked up the compression ratio in your engine, high octane fuel by itself isn't going to make your car faster.

For the vast majority of you, all premium fuel is going to do is make you feel all warm and fuzzy because you think you're doing something special for your car (even though you're not). Gas stations and fuel companies really love you guys though, as they're making a handsome profit off of you saps!

 

Just like putting in crappy 87 octane is going to make you feel all warm and fuzzy b/c you're saving a few bucks. But alas, your car knows what you're doing to it. And your Mazda has plans for you my son........dark, horrid, plans that will send you into the deep dark depths of hell

 

This is what I like to see..........

Thank you ProtegeMaster.......

I did not want to spend the time to write all this down.....
