We purchased a new 08 a couple months back, and were told that with the 08's, you no longer needed to use premium gasoline - that that was one of the major changes that were made. Also, the dealership mechanic ( who was elderly and appeared to be one of those very wise mechanics that know so much more than the young guys) told us that whichever fuel type we chose, to stick with it. don't change, don't try to use regular and then every once in a while fill the tank w/ premium to "help it" ( which is something I would do!). He said that is the worst thing to do, that once we start on regular, stick with it, the engine calibrates itsself to it, or something like that.
My question is 1) is that true that we don't need to use premium (even tho the owners manual has not been changed to state that regular is ok) and 2) is he correct about the consistency in the type of fuel used? thanks very much and p.s. we absolutely LOVE the power this car has. Had a Pacifica previous and it was a dog. ( but miss the interior space.)
