Does your Spouse support your hypermiling?

[low&slow]

I have been riding my motorcycle a lot more and driving less. My wife has needed to use my car a fair amount recently as I did some maintenance on her SUV or I needed to use the SUV for the extra carrying capacity . Her driving my car knocked my tankfill average in my Jag from around 28- 30 mpg to 24- 26 mpg tankfills. This was with me doing about half the driving for these tankfills. She is wonderful and the love but of wife but definitely not a hypermiler.
Just to see if she would notice, I started doing a few " stealth mods" to her SUV to see if she would notice ( upper grille block, removed roof carrier crossbars, upped tire pressures to 42 psi). So far she has only noticed the higher tire inflation and asked me to reduce it back to the manufacturer recommendation. Its kind of amusing, like Spy vs Spy or Roadrunner vs Wiley Coyote.
