    2011 ESV Platinum escalade-Gas question

    Hello,

    I'm new to this forum as I just got my 2011 escalade today! I'm sure this question ahead popped up several times, but I just wanted to know what octane everyone uses? The Cadillac dealership said they use 87 in all their vehicles but as I went to the gas pump, the gas door says premium or E85 (not available in my area), is it really okay to use 87 or does it have to be premium? I just sold my QX56 which use to give me problems if I used anything less than 93, just curious. Sorry to annoy anyone but hope

    ----------

    Hopefully you all will welcome me with open arms! Lol

    Welcome with open arms. There is another thread open about this. The answer is, 91 is preferred, but 87 will work in a reduced fashion and is not recommended.

    91 octane here in California.
    Chevron only.

    Hope you realize that the same truck from the same refinery delivers to several "brands" gas stations every day. And the source can change as often as monthly, depending on prices, contracts running out... Your Chevron can be selling the same fuel as the mobile down the street, and the no name gas station down the street.

    If you're really concerned with "better" fuel, google top tier fuel.

    OP,
    I'd strongly suggest you do a little reading on what octane rating is, what it can and can't affect, and under what conditions it actually makes a difference. Realize that "premium" doesn't mean "better". Higher octane fuel is more resistant to igniting under the heat of compression. It contains no more hydrocarbons (power content) or detergents than lower octane fuels. In a nutshell, if you're not planning on much full throttle/near full throttle operation, towing, or racing, 87 is just fine.

    I have owned five (5) ESV's to date. I have always run the 93 octane in my vehicles.

    Operated my '07 for 200K and only used 87. No problems.

    I figure since I spent 80k on a vehicle, I should go ahead and spend the extra few cents every fill-up on the higher octane gas. 93 is all I run in my Escalade, Denali and both Infinitis.

    Not saying I know what's right but my experience is as follows:
    Got the 07 EXt with 50k miles. Drove 3k miles on 87 octane. started getting increasingly louder ticking noise for the first 5-10 minutes when the engine was cold in the mornings. Switched to 91 octane and the ticking noise gradually went away to where I don't notice it any more. No difference in outside temperatures. I am personally sure my 07 wants 91 or better

    Open your owners manual, it will tell you what to use. There are non Escalade owners here that will give you wrong information, that may or may not damage your truck, listen to Escalade owners, not Escalade want to be owners.

    This always been an ongoing question. The manual say premium gas recommend. 87 octane will run fine, but will reduce in power and some knocking. If you can live with the knocking or don't want to go fast, 87 is fine. If you want to be safe than sorry or have a lead foot, then use premium.

    Why not just bump up slightly and go with 89 octane and see if that helps with the knocking & pinging ?
    Also to smooth it out add some Marvels Mystery Oil to the motor oil and gas. Probably 12 oz for the ESV gas. Really quiets an engine and smoothes out the response.
