my new Charger SRT-8

hey guys.... i just got my new black 06 Charger SRT-8 from Carmax about less than a month ago.

i got a few questions.

what kind of oil do you guys recommand i should feed her? i used to feed my old eclipse the best Mobile One Synthetic. should i use that for the SRT-8 too?

also, is it normal that i get 12-14.5 MPG for city and highway, i thought highway suppose to be 20mpg.

other than that, i love my car

Stay with synthetic.

i just found the answers to my own questions.

poped open the hood, saw the oil cap says Mobile 1 Synthetic 0W40.

and i looked up fueleconomy.com website, the mileage i am getting actually is normal.

so that's all i needed to know. just wanna make sure nothing's wrong with it.


thanks guys.
