    Simple answer? Nope. Not if you have converters on it. Also, the O2 sensors are adversely affected. Shortens their life substantially.

    C10 is your best choice.

    Why bother using race gas if your car isn't tuned for it? Unless your car is turboed, I don't really see the point outside of pouring money down the drain and if you like to change o2 sensors.

    I dont have cats ...they were removed along with headers ....and o2 sensors where reprogrammed so light doesnt come on , as well as my ecu being tuned ! ...so still wondering which I should be mixing in with pump gas for optimum performance !!

    Not sure how much more you can really squeeze out of the engine with a leaded fuel, I think your best bet would be MS109.

    An engine only needs as much octane to prevent it from detonating. Any higher than that is a waste of money.
    In fact, on street engines, too high of octane can lead to horsepower loss.
    I don't know the magic octane number for these cars, but the ECU will retard timing if knock is sensed, but when there is no knock and full ECU timing is allowed there is no horsepower to be gained from more octane.

    MS 109 can be mixed with pump gas! I ran that combo in a turbo 911 for four years!

    k thanks .... ya know after doing some research the leaded fuels do much well for an engine coating all valves rings and soft engine componants ....only isuue is fouling of cats , and sensors which I do not have on my car ....im thinking of a little lead action here whatcha think ???

    You still have sensors on the pipes, just connected to those extenders.. and the ECU is set so it's not so sensitive to not throw a CEL.. if you run leaded, you can have problems with the sensors, so if you run leaded, run a tank of leaded then a tank of unleaded. I didn't think it was worth the extra hassle, so I just run straight ms109 and the car runs great!
