Different topic.
I just bought a new car that "requires" premium (91 octane) but will run on 87. Is the cost difference in mpg vs cost /gallon generally worth using 91 vs 87?
I know there are a lot of variables, but I will spend more money on "better" gas if it gets me 2 mpg better in mileage. Thought is that it is a net zero between the two, but it is better for the engine in the long run.
I haven't done the math and the car is too new to be able to find a distinction...yet
A possible alternative issue is the with the same cost/mile and better for the engine, it might be a tad faster. Not that is needed to go sub 5.2 0-60.
