    Default Gas Question

    I spoke with mechanic today, he believes that Discovery II engine was designed for the lowest gas. He sad there is no need for premium

    Read the manual,

    My 04's manual says to use premium as reduced performance and economy will result if you use lower octane gas. i haven't tried it yet, but i run 87 in my 97 with out a hitch and get better gas mileage out of it.

    I believe all Discos are able to run lower octane gas due to the knock sensor, but they are designed to run premium.

    Man, I have looked into this before, and everything I have ever read speaks about the need for premium as it burns cooler. With the aluminum block and all the talk of the accompanying troubles with it, I guess I have been terrorized into complying, and using the premium.

    I have been dumping tons of jack into my '02's tank for years now, and I guess I do it because it is my wife's DD and the only reliable transportation in the family.

    After reading this, as soon as we get a more reliable vehicle in the family, I'm going straight 87, baby.

    The lower grades of gas have fewer engine cleaning additives, and they are a lot more likely to leave yo with carbon fouling trouble. In addition, the lower octane fuel results in higher combustion temps, which markedly increases the chance of liner failure in the motor.

    If the use of cheap gas costs you a motor or even a valve job the savings aren't worth it.

    Just figured I would drop in my two cents....

    I ran 87 oct in my 99 DI for about 6 months last summer.

    In the fall, I heard a lower engine knocking when warm.

    This truck has never had any problems and I thought I may had spun a bearing or something....turns out I toasted the cat!

    Reg is not worth it! In my 97 DI....179K Original Cat and o2's....always used 91 or higher
