If you can find it, look for a fuel consumption map for your particular engine.
I wish I could find one. Yes I've seen the BSFC map page here, and searched elsewhere.

I'm familiar with the concept and my toy v6 is probably most efficient in that area also. (What is BMSC?)

I agree with that, but that isn't DWL as defined in the wiki here (sorry I'm a noob & it won't let me post a link):
"In other words, you will back off the accelerator and lose speed (possibly also downshifting) as you climb, and gain that speed back on the descent."
For most cars, when cruising we're at low throttle opening, either backing off, or constant throttle doesn't get the engine close to peak efficiency.

HTH, Jim.
