What Octane Do You Use In Your 4.0L V6?

Now, I don't claim to be any kind petrolium engineer (I only claimed to have worked in a gas station, ) but I am quite sure octane is not gas. Octane is a component of gas (not to be confused with octane rating which is gases resistance to detonation,) right? So, wouldn't it be possible for my claim that octane could be seperated from the gas? I heard this from our gas delivery guy, it could be wrong, but I tend to believe him as he had worked in the industry for decades.

 

mmmmmmmm........gas fumes..........


.......delicious!

 

Yeah, you may be right.

 

I usez 1 millions ocatanez in my Silverados... but that's because it's a piece of shit... and the extra octanez yo makes it foshizzle better...

oh... and Balboa, you are a douche

 

I filled the last two tanks with the 91 and I did not notice a difference in economy. I need to do a more precise measurement just to see what the deal is.

I paid on average 3 bucks more to fill with 91, may not be much but it bet it sure ads up over a few years.

 

No, No, No. You misunderstand. Let me make this more clear for you. ready?




You ARE the douche.

 

I was just doing you a favor and clearing up what you may not have understood. No where did I call you a douche. Others have and I was just pointing out the grammatical statement that pointed to you as said douche. Feel free to read the post saying that you are infact, a douche.

 

What gas type do you have to put in the v6? i heard 89, can someone confirm that?

Thanks

 

I use 87.

 

i have never used nothing below 89 oct.i usually burn 92/93 oct. but the damb prices r $3.00+ a gallon now.

 

SSSSEEEAAARRRRCCCCCHHHHH!!!!

manual calls for 91, but down to 87 may be used w/ decreased (see retarded timing) performance.

i've used 87 since day one. tried 91 for 6 fillups last year when gas was cheap...no difference in mileage or butt dyno...
