Testing your glide. Are people doing this?

On my IMC (instrument flying) rating renewal last year,
I took off (not in my plane, but a rented PA28)... when
I got to cruising altitude I levelled out, brought the throttle
back then leaned the mixture. The examiner said "There's a
man who owns his own plane."...he was referring to leaning
the mixture, something I'd always been taught to do from day
one of my training. He said a lot of renters fly around with
mixture fully rich all the time. Even a pilot friend of mine
commented that he never leans the mixture because he
"never flies above 2000ft".

That's good to know. On balance, do you see any difference between
owners and renters?
