    I always run 93 octane here in Pennsylvania and always look for 93 where ever I travel to. It costs a bit more, but I'd rather play it safe. Turbo motors tend to perform better with higher octane levels. Higher octane also reduces detonation which is very bad for your engine.

    93, the savings is so minimal it's not worth it.

    If the owners manual says "at least 87 octane" then 87 should be safe if not optimum. Modern engines have knock sensors containing piezo-electric crystals that are usually screwed into the block and are calibrated to recognize unwanted pre-ignition. They simply send the info to the computer which pulls timing back or whatever needs to be done to drop knock below undesired levels. So unless you are running something like "white gas" with terrible pre-ignition characteristics, any fuel above 87 should be at least safe and within the ability of the computer to manage. Where I live the difference between 87 and 93 (usually only 91) is about $5.00-6.00 per tank.

    Depending on gas prices, I've used both regular and premium on this car and honestly saw very little difference for daily driving.
