Neither engine requires premium gas. So far I have used regular in my 4.6 and it doesn't seem to suffer at all. The articles say premium will buy you a few more horses, but I don't see any need for it. I have observed no pinging or dieseling that V8s of years-ago exhibited on regular. I don't plan on changing. I have read very good things about the 3.8 engine and it is a bit less powerful, but doesn't seem to lose much in horse, zero to 60 or quarter mile, when compared to the 4.6.Are both the 3.8 and 4.6 liter running on premium gas or is it only the bigger engine that needs the more expensive gas.
If your buying a $40K car and are concearned about gas prices or mileage, your buying the wrong car.Good to know about the premium, save some money at the pump due to the high prices these days
I don't agree....if I could get very similar cars for $40,000 but one has better gas mileage or only one takes premium gas, why would it not be a concern?If your buying a $40K car and are concearned about gas prices or mileage, your buying the wrong car.![]()
