The 06 SS get 17 if I'm lucky, but who cares, it's fricken fast!
The 99' gets about 24.
And I call shenanigans on the guy who says he's getting over 500 miles on one tank and still has gas left over. What did you do, pull the motor and replace it with you lawn mower engine? Come on, if your going to brag make it believable.
[:'(]

 

over here on base the gas tends to have water in it and also some numbers that are not always beliveabel for octaine.
So i mosty use it for the water and to help burn anything that might get in to the motor form the gas.

so in threoy im trying to use it more as a preventive maintnace for the car then anythign else.

 

Okay, I can understand if you don't believe the octane ratings at the pump. Though, I don't see how it helps burn anything extraneous in the engine. Octane is resistive to ignition saving your engine from premature spark due to high compression and it's proportionally increased temperatures. That's it. But, if you know something, I'd like to hear. My friend and I have been trying to figure out these octane myths. I have heard that it's good to put extra octane in your tank if you've got excessive water... But I don't understand why.

 

you kind of answerd your own questions here.
it causes high temps, there fore it causes water to pass threw the system batter. also if there is anythign in the ground tank that can burn saftly it will do so to a point.

But by no means do i say it is a cure all, but i can't get heat here or i would run it in there every so offten also. to do the same thing.
Like i said for the most part it is preventitive for me not that im running down a race track etc. but it dose help the car run better with out the water in the tank.

 

My last tank of gas was probably the best I've ever had at 28.34 MPG.

 

3.8L in town 18-20mpg highway 75-80mph i get 30-34mpg

 

Mickey im curious to why your using 93 octane and octane booster. It seems like people that say my car runs so much faster and better on those who dont understand octane rating and what it pertains to. Octane is the ability to resist knock or pre -ignition. If youve ever driven an old car, say something in the 60's with a v8 and the timing is way too advanced it will have spark kock..thats what high octane gas is made for due to the higher compession ratio of older engines. Puting 93 octane actually hinders performance on a car that does not require it due to it not burning completly since there isnt enough heat to ignite a gas made to be in an engine that can produce that kinda of heat through compression. Your wasting so much money with 93 and an additive, not to mention with imcomplete combustion all the carbon left over that onlt acts like a sponge to the incoming fuel. The amaco commercials are very misleading in thinking that amaco ultimate is what everyone should run in the car to make it run clean. Octane has NOTHING to do with how clean as fuel is, making it sound like something of a lesser octane is a dirty or watered down gas. If you want good proof of how octance works, put some 111 octane in yoru car and see if it even starts, or better yet find someone with a old school car thats had some work done to it to get the compression up to about 12:1 and see if they can tell you what that engine sounds like with anything less than o ver 100 octane

 

yes i am aware of the "old school cars" I have owened and rebuilt several of them . also some that had nice motors in them that when i built them i intend them to be more then normal comp.

I relise that the comp. has a lot to do with heat also. I use it once in a while not a daily thing. normally i use the mid grade as it tends to move faster threw the pumps here and therfore dont sit as long in the undgeround tanks so it has less setteld n the tank and you dont get the crap off the bottom of the tanks HERE

you have to relise im not in the states where the gas stations are regulated and checked as offten. here they tend to check them yearly if that and also just enough to say they are still holding gas.

so i understand what your saying. i do it alot of the time to help it burn a bit hotter then it normally would JUST TO GET RID OF THE CRAP OUT OF THE MOTOR. AND NOT FOR PREFORMANCE .

i have also answerd this in here a few times. if you read up farther you will see this.

Might be wasting money but to me it is worth it from the diffrence i have seen in MY CAR.

not in anyway saying it is something that you or anyone needs or should do for your own cars.
