The wife and I took the grandkids to Disneyland a couple of weeks ago and rented an '05 Excursion with the V10 (don't know if it was 2 or 3vavle engine). Anyway I was quite impressed with overall performance and mileage. We took the SE route on 395 and mostly used cruize control between 70 and 80 mph. 14.2 mpg hand calculated over entire trip. The V10 didn't have the passing power of my 6.0 but was still pretty impressive. Nice engine.
