This doesn't really directly answer your question, but.....

I rely on the sound (pitch) of engine. (Especially since repairing my
odometer and it now reads 10-15 km too fast!)

In general I:

- don't lug it.
- don't rev past red marks on speedo (if you got em, and if your
speedo is correct!)
- keep revs up especially on hills. This keeps cooling fan spinning at
a more efficient rate. On long hills, I check the head temp gauge.

As for road speed, yes; not over 100-105 km/hr. Sure you can, and i
have (though I didn't like the sound of things and frankly couldn't
hear engine pitch with all the road noise) but why? I just "right lane
it" when I can. I try not to be in a hurry. And I stay off major
routes like I5 when possible.

Don't know if that helps, hopefully it shed some light!
