Saturday I picked up my new 320. The transaction and delivery went smoothly. The dealers final comment as I pulled away was to keep the speed at or below 65. As luck would have it my GPS immediately put me on the Toll Roads surrounding Austin in my return trip to Houston. Unfortunately the speed limits ranged between 70 and 80 mpg. At 65 I felt more like an obstacle than part of the surrounding traffic. After about an hour of this I began to un-pucker enough to begin to relax. It was at this point that I realized that I was driving in overdrive ( have a 2016 Honda Pilot with a 6 speed tranny) and I had the ECO button depressed. My gas mileage had dropped from the typical 24/25 mpg to 12/13. Yikes. Which brings me to my question.... When towing, is it suggested that OD be engaged, and what effect does the ECO button have.
Bear in mind the most of Texas is reasonably flatish.

This post about Towing and RPM helped me: http://tabforum.nucamprv.com/#/discussion/7113/towing-and-rpm
From the above discussion, on a recent trip, I learned not to drive in overdrive unless on a highway and my RPM's were high enough the car wasn't lugging. Driving in 4th made towing much smoother (I have a 5 speed automatic).

As a kid I lived in northern New Mexico and during the winter months the highway was full of vacationing Texas license plate cars with less then ideal snowy road driving skills. My father [well before politically correct was a term] would roar . . . If God wanted Texans to ski, he would have given them a mountain . . .
Your Pilot owners manual (page 471) says 'D' which includes OD gears 5 & 6 is fine on flatish roads and that the 'D4' button should be used when:
- - Going up or down [steep] hills
- - Towing a trailer in hilly terrain
Your MPG drop is realistic for Pilot size vehicles when traveling above 65 MPH, you should do slightly better in the 60-65 MPH range. Relax, get into the right hand lane, don't worry about folks passing you. While Texas maximum legal trailer towing speed is 70 MPH you can go slower and most states have trailer legal limits well below 70.
From the Owners Manual limited description of the ECO button function, I wouldn't use it while towing as it slows engine response.
BTW, Honda owners manuals seem to have some of the best information on Trailer Towing of any manufacturer. Well worth reading from time to time.

I normally drive between 60-65, and on level ground our Sienna seems happy at around 2300 rpm.

I see that you were driving from Austin to Houston after picking up your 320. Did you get your 320 at Princess Craft in Round Rock? We bought our 400 there based solely on recommendations from people on this forum--it was good advice and we have been pleased with the after-purchase service.
When hubby and I returned home to Dallas with our new T@B, hubby intentionally did NOT take the interstate because he was worried about keeping up with traffic, etc. It was a miserable trip over those bumpy, windy state roads. On a subsequent trip from Dallas to the dealer, hubby did take the interstate, drove about 65 mph, and he said it was the way to go. Easy driving, and he didn't worry about local traffic coming and going onto the road.
Oh, dear, another hi-jack. Well, folks on this forum are helpful and friendly even though not always on track.
