The manual says "86 or higher"...leading me to ascertain that 86 is the lowest, minimally acceptable, octane-rated fuel for suggested use. (It also suggests using premium if there's knocking or pinging) The higher the octane, the slower it burns. My truck manual calls for the same fuel, but I've always noticed that a tank of 92 octane will last longer than a tank of 87.manual must of lied when it says 87...
all you guys running premium are wasting your cash..
i got a buddy that runs premium in EVERYTHING he owns, even his lawnmower.. He thinks because its more expensive and is called "premium" it MUST be better. People with that mentality annoy me (no offense to anyone like that on here though)
Here is a question to anyone running premium. Do you know the difference between premium and regular? I mean as in what happens inside your engine when the gas is ignited..
