    I drove from CT to Buffalo and back over the past few days in my 80 -- it was a great drive, and comfortable!

    Here's a couple of observations / questions I had --

    - I drove 150 miles at 72 mph on cruise control -- with the AC on the 1st of 4 settings -- and got 18 mpg -- !!

    - The cruise crontrol was on a majority of the time -- at two points, the cruise dropped down 5-10 mph and then corrected itself -- like it was faultering -- is this normal? I was on a flat road --

    - I installed George's LEDs -- amazing! &nbsp:Did the map-lamps and the interior lights -- what a difference! He should make them for the tail-lamps and side-markers!

    - my oil is 1,000 miles old, and when I check it when filling-up, it's still golden, like a fresh install -- !!

    - I was a back-seat passenger at one point and the gear noise from the drive-train is more noticeable than when driving -- this gear noise (like a tank's) is normal, right??!! Also, when accelerating to 60 mph, I always get some odd harmonic distortions from the drivetrain -- again, normal??!!

    THANKS!!

    There are several of us the have it, me too. I think we are the lucky ones, maybe not. No known fix.

    I don't think 18 MPG is normal. I once did a run at a constant 56mph and got 16mpg (and that's allowing for differing volumes in UK/US gallons) I don't suppose you're too worried about getting 18mpg though :D

    I just drove from Oregon to Utah (~1k miles) and averaged 15 [sup]1[/sup]/[sub]2[/sub], and that was great for me.

    I vary between 6 to 6-1/2 mpg :eek:

    Rogue,

    >> 15 1/2 (done properly) <<

    My you're clever. How'd you do that?
    Let me try something....
     ¨÷ ¨ø ¨ü ¨ý ¨þ ♫ ¢Ü ¨ù ¨ö ¨ú ©ö/2

    No, that isn't working.
    Maybe the sup/sub tags... [sup]1[/sup]/[sub]2[/sub]

    Yes! That's it.

    Similar experiences for me two weeks ago to / from Orlando.

    ...annoying harmonics from drivetrain, more noticable in back seat than in DS
    ...MPG @ 60-65 w/cruise & AC: 14 /12 - 15.
    ...MPG @ 75-80, w/cruise & AC: 16
