OOOOPPSSS! Boy I really said that wrong didn't I. Don't worry, I haven't made that mistake (not yet at least). To clarify I have only run diesel fuel in the car

Speaking of...can anyone tell me the benefits of running 45 cetane as opposed to 40? My manual doesn't reference 45 but the station I fill up (with diesel) only has 45 while all the other pumps in town run 40.
