Can I use a 5w30 weight oil [Mobil 1] in my 03 Expedition 5.4 L V8

5w-30 Mobile 1 oil should work fine in your Expy. I use 0w-40 John Deere synthetic oil year around in all my vehicles. I haven't had any problems in the last 10 years.

Thanks..........I didn't think there would be a problem, the dealers want you to come back for oil changes by the public that warranty can be voided if there is damage caused by improper specs, .etc.
