    Fuel additive?

    2012 owners manual says use fuel additive every 7500 miles. Does anyone know what brand and type is recommended?

    if you notice in your owners manual there is a *6 next recommendation, which states only if TOP TIER detergent gasoline is not available, one bottle of additive is recommended.

    check out this thread on post #11 for further details

    Kia recommends Techron. Compositionally it's 40-70% light saturated hydrocarbons (probably C5-C10), 10-40% medium hydrocarbons (>65% C10), and the balance a bunch of alkylated aromatics. Essentially stuff that will dissolve carbon buildup and gunk, but not wash out motor oil.

    STP and amsoil are similar in composition. I tend to stay away from other brands that contain alcohols and/or ether amines etc, which are a little harsh.

    I usually run a bottle a tank or 2 ahead of when I need to get an oil change, so that anything that gets cleaned out and picked up in the oil will get drained out sooner rather than later.

    Question: If you already use Chevron gas all the time (with Techron) do you still need to do the additive at service intervals???

    If you're not using a Top Tier fuel all the time, the Kia TSB recommends a bottle of Techron with every 7500 mile oil change. It doesn't hurt the engine or anything if you do use a bottle every oil change even if you use a Top Tier fuel. Compositionally, adding it probably raises the octane # ever so slightly, but not enough to affect anything.

    Since we (most of us anyway, except for a few EXPERTS) don't really know how much Techron is actually IN Chevron gas, I just put in a bottle with each oil change, at 3k miles. I have noticed that my little Gertrude (Soul) seems a bit peppier after I put in the Techron gas treatment. It's like Candy to her!
    The smallest bottle of Techron that they sell, is for 12-15 gallons of gas. That's plenty for the little tank on the Soul.
    It may not be the only gasoline additive out there, but it's the only one recommended by KIA. That pretty well settles it for me.

    Any difference in performance is strictly placebo effect. There's nothing compositionally that burns with any more power than plain old gasoline... Worse, actually... Stoddard solvent is like kerosene, smoky and slow burning, as are the alkylated benzenes. But they're more greasy than gasoline in order to dissolve up deposits.

    Only in the Bay Area, would you put stoddard solvent in your car. How did that get into this conversation anyway?

    I thought we were talking about Chevron Techron. Eh?

    If KIA says that's what we should use, then dang it, that's what we should use.

    Case Closed.

    That 10-40% medium hydrocarbons in Techron *is* the stoddard solvent (which is why I put >65% C10 hydrocarbons, which defines stoddard as opposed to plain kerosenes)...
