Regular or high test gasoline
I have a 24' motor home with a Ford V10 gas engine. Was wondering if anyone has gave it an honest test for gas mileage using high test vs regular. Is it worth the money difference ?

The latest generation of digitally controlled engines can better compensate for fuel quality, but years ago I drove 1984 Volvo, what was 1st generation of digital engine management.
The engine was design for regural, but with 112HP it was struggling on long grades we have in CA.
So for annual trips to Las Vegas I was fueling with Premium.
Thanks to that instead of redlining on lower gear, the engine would pull the grades on overdrive.
I did not do it for fuel saving, but for time saving, but strongly believe that avoiding downshifting saved fuel as well.
Maybe not to degree to make it worth spending extra money, but to consider.
