Just went on a 300 Mi trip last night. Most of the time at 75 MPH. (70 MPH zone, don't send me a ticket). Got about 30MPG I figure. 2 things I forgot to mention:

There is no tranny dipstick so don't look for it.

The Oil need for a drain and filter change is 5.8 Qts, not 6.5 as the manual says. Gillly said so also in an old post and I know because I put in 5.9 and it went over the full mark a little. That's the only mistake in the manual that I know of other than they neglected to tell you to check the battery water level, but that was corrected later with a recall that added a sticker on the appropriate page with that info, and a sticker under the hood (and a new battery in some cases).

Also I think the manuals said to use regular oil but later that was revised to Mobil 1 0W40 to support the FSS extended maintenance intervals.
