I use conventional Peak 10W30 in my Dakota. Peak has a good dose of Moly and Boron and my truck runs great on it, very quiet and smooth idle with good power and MPG. It burns about half a quart every 2200 miles. I stocked up on the BOGO sale at Dollar General last November. I ran Peak 5W20 in my wife's Honda Accord before we gave the car to her mother, it did a fine job in her car too. I sent 8 quarts with the car when we gave her the keys. Peak is an excellent oil. The local Napa store here sells it in 6 quart half cases.
