Meanwhile, my old civic that I put 40k km from 116k km to 156k km, I never had to top it off ever...
Same, I have a bottle of scion blue premixed (55/45 mix in Canada) that I just top off every 6 months or so... only cost me $15 for 3.7L jug.

Hah, I did the same sort of thing as you. Funny thing is I lost coolant from normal driving over the past year (from over the Max to below the Min mark), but after my last time topping it off a few months back (actually past the max again...oops), and driving about 2500 miles for a road trip (about 1900 of it was long stints of highway cruising, the rest a mixed bag of all sorts of driving at my destination) the coolant level hasn't moved a bit, and I didn't burn a drop of oil, either. I expected what happened to you to happen to me. I know the automatics run the engine lower at the same speeds, but I was expecting to have lost some coolant over all of that driving (where only one day was low enough temp to be in the high 80s), and at least a little bit of oil. At 70mph in 6th the engine's only running around 2500rpms, so I could certainly do worse for straining the engine and its systems over a long period, but until they see fit to make the national speed limit 85mph......
Anyway, not complaining at all about not losing fluids, but it's funny to me that my normal commuting and local driving seems to take more of a toll on the system than a ton of highway running putting 2 months of miles on a car in a week.
