LA318 question

At 24-ish mpg’s, that’s helpful here in Florida. At least when you hit the interstate Hwy’s for a trip. My ‘18 Ram 1500 gets 20 at interstate speeds. I can do better going slow on A1A. LOL! But that’s practically leisure driving at 45 mph.
I find keeping the rpm below 2000 is best for mileage. Even my wife's newer Buick.
