LA318 question

lol, yes, the low rpm’s help. That’s why I mentioned A1A which is a very slow going route here in Florida. As long as you don’t get hammered with lights when you “Get into town”, you can do very well. In my truck, as long as I’m not in a crowded area where the larger population is, the interstate (I-95) is more relaxed, less cars. I can back the speed down a bit. The best I’ve done in the empty parts of I-95 has been 24 mpg. Nominally it’s 22.
When I lived in Jax, back in the 80s, we'd Roll A-1A up and down the Coast.. Man, the were Good Times!
