What Octane should be used?

[My01yuk]

Trust me, I'm not concerned about the $5, but if there is no gain why do it? That's my point, I could use that $5 for somethinig else(Beer). I see your point though, but as long as there is no gain in using higher octane, I will stick to lower octane. In the end I think it's a matter of personal preference.

I say...always run 91 at minimum unless you drive a beater...whether it calls for it or not...if it requires 87, typically, 91 wont cause any damage

Just waisting money bro. Higher octaine fuel does NOTHING for you without a high compression motor

peace of mind knowing I'm putting the best quality stuff in my vehicle possible...


why get an Escalade over a Tahoe? Just better quality...


whether I see a difference or not, its nice to know Im using the best quality possible for a mere $5


I also only use Royal Purple Oil...which is why Im 15k miles past due...and theres no issues... (and yea...even with RP, I shoulda changed it 10k ago)

$5 is not a waste of money...$5 is a joke lol....Im sure you piss out more then $5 of beer per week..




you wont get knocking as easy with 91..thats for sure...
plus, I'm tuned for 91 anyways...so I have to run it now

And the Escalade has a higher compression engine then the Yukon/Tahoe

I get a mileage increase that makes the $5 a tank worth it.

SteveK there is no way you get better mileage, unless something is messed up in your engine.
Using 91 (when the car does not call for it, or need it due to mods) is more likely to cause MPG loss to be honet, at a more expensive rate. Not only is this info all over online, I have witnessed this with my Tahoe too.

X2. Just because it is a higher octane does not make it better gas. A higher octane fuel does NOTHING for you with these engines unless you have a tune that calls for it. High-octane fuels only become necessary when your engine has a high compression ratio which these engines do not. Octane is NOT a measure of power but of the fuels’ resistance to ignition from heat. The octane rating is the fuel's resistance to spontaneous combustion under compression. The higher the octane rating, the more compression it takes to make the fuel spontaneously ignite.
A high compression engine requires higher octane fuel to prevent detonation. Detonation is a condition where the fuel air mixture ignites while being compressed before the spark plug fires. Detonation can cause serious internal damage to an engine.

None of you guys will ever keep your vehicle long enough to see 91 vs 87 do any good or bad to your truck...thats all there is to it

If you wanna pay an extra $5 at the pump...do it...if not, dont...(unless you own an escalade which comes with a higher compression engine)


Do you want to spend the extra money on 24s? or keep stock 22s?

Wanna spend more money your "gucci stunna shades" or some regular sunglasses?



If you want to spend the extra money...do it...if not, dont...like I said...NONE of you will ever keep your truck long enough to see 91 cause damage to the truck

Escalade engine = Denali engine = L92 engine

The gas fuel door calls for premium fuel, manual calls for premium fuel.

I drive the same routine every week. Same highway miles, same city mileage. Refuel less than a tank a week. I measure with the pump gallon number and the mileage on the odometer. Don't know what you want me to say, I consistently get different numbers with different gas.

I kind of agree with that. But when I think about that I can't imagine someone thinking another person is "cool" becuase they use higher octane gas.
Nobody will even know you use it unless its the guy in the station, or due to a decal you installed or something.
People can see the Gucci shades and 24s though......
And may even think that your a badass!

And also SteveK you have a Denali, same engine with an Esky, so you have a reason to use it since it calls for it.

Nah...Its about you and what you think...If it makes you feel good that you use the most expensive gas, most expensive oil, most expensive vehicle...thats all that matters


Most people that spend money on getting the top of the line model of a vehicle will spend the money on the more expensive gas and oil just because its the kind of person they are...just because they can


Im not rich...but it makes me feel better about myself when I pull up in my Denali and load it full of premium...right next to some broke ass punk in a busted ass civic complaining about the price of half a tank of regular...I just think to myself...what a loser

And the Denali and Escalade dont have the same engine...or...didnt...at least the NBS didnt... you say they both run the same engine in the NNBS?
