i was reading on the boards about people running it, some with success some without.

so i got a bottle of octane booster and ran my tank to E, put $10 of 87 in and it ran fine and even idled a tad better, i gunned it up to redline and it was extremely smooth and cruised fine in 6th gear. so i ran that out and filled my tank with 87, only a $5 or $6 difference btw compared to 93. but i managed to get 153 miles at half a tank, im at half a tank now with 93 octane and am sitting right at 93 miles...ran them the same way, redline it on the entrance ramp, then cruise highest gear possible till im out of gas

so take what you want from this, im in Houston, TX btw.

 

Gas is cheap. Engines are expensive.

 

just run 93. stay on the safe side.

 

im already back on 93, i ran 87 just to see

 

Bad things happen over time, not one tank. We know it will burn the fuel and if you don't have the correct fuel available, then you do what you must. The long term health of motor requires the correct octane.

 

I use 91 octane Chevron with techron. Never used lower octane than 91, just to be safe.

 

Yea I wish we had 93 as premium out here.

 

You got 153 miles on half a tank??? Wow that's a pretty big difference.
I usually get about 200-220 a tank with 50/50 city and highway.

 

but i managed to get 153 miles at half a tank, im at half a tank now with 93 octane and am sitting right at 93 miles..

Couldn't be that you have misjudged the 'halfway' point on your gas gauge?

....or are you really claiming that you got 60% more mpg from your 87 octane fill-up?

 

Trolling?

 

why do we have to go through this kinda **** every month?

 

Because there is a naive person born every day?

 

lol no i seriously got that mileage, my word can only go so far online i guess so once again take it as you sit fit.

 

I ran 87..original engine still..and premix..

 

Bullshit buddy. Running lower octane gas doesn't increase gas mileage by over 60%.

 

how the does that equate to 60%???

93 to 123??

nm, i see..sorry i meant 123 not 153 was typing with my num pad

 

The gas gauge is inaccurate. You cannot estimate the real consumption based on that.
Only when you fill up again (and know how many miles you drove since the last fill-up) will you know your exact fuel mileage.

 

maybe it had less ethanol in it.

 

what part of houston do you live in btw?

 

I once got 230 miles on "halfatank"....well it wasn't right on the halfway, but within a half inch.

Then I mis-typed and got 530, because I had nitrogen in my tires.

S

 

i didnt know they were inaccurate lol ive just been guessimating by taking my trip meter and dividing it by 8 when i reach half a tank. i know its off but i ive been getting my rough estimates from that method

im by hobby btw

 

Even still, there's no way a change in octane (+ or -) is going to net a 32% difference.

I'm not calling you a liar, I'm saying that your methodology is flawed (using the fuel gauge, presuming you are driving exactly the same and under the exact same condions.)

 

LOL, a trolling Mod

 

Not agreeing but if you take the miles gained plus add the money saved???
