With the HyTi I had, I would lock the fob in the car and use the keypad for entry ... except in Winter when I'd remote start it if needed. I wanted to do the same with the current car but experienced trouble - keypad didn't seem to work. Turns out it was a DOA pad from the factory. Was replaced a couple weeks ago and works like a charm. Interestingly, the first attempt to get a pad ordered resulted in a Fusion labeled carton with an F-150 pad in it! <chuckle> Warranty, so the total was my favorite - zero!
In one of the threads somewhere here, someone posted that they used non-Eco mode as they felt Eco didn't gain anything appreciable in the MPG arena. I was a devout Eco-mode user so I thought I'd see what would happen in the two modes. I actually added a third test mode: mixed.
I made no adjustments to driving - either style or roads or anything. I do not "hypermile" as some do and sometimes will literally drive it like I stole it. Highway driving is 5-8 MPH over limit in most cases. All MPG numbers are from the gas receipts and not the car computer. Dates for tallies begin May 1 and end as of today.
Eco-mode: Eco cruise activated all the time. If added acceleration needed, use the gas pedal.
..... 4 tanks totaling 1670.6 miles; average MPG per tank 43.53
Mixed-mode: Eco cruise mostly BUT turned off when on long uphill areas or needed a bit extra punch getting to speed.
..... 2 tanks - 919.0 miles; average MPG per tank 41.42
Normal-mode: The usual ... Eco is off and not used at all.
..... 4 tanks totaling 1616.1 miles; average MPG 43.98
So one could get about 1/2 mile per gallon by NOT using Eco mode., To me, that makes it nearly a tossup. Mixed mode appears to be a losing proposition. <shrug>
By no means is this anything near sanctioned testing but just a drivers curiosity on a remark from one our other owners. Do with it what you will!
