Hi there. I am new to this board. I have a 2007 Dodge Dakota 3.7 Liter V6. I am about to send out for my first time oil analysis next week. Anyone here have a recommendation for what oil to use for this truck. I use it for a small pest control business I run and probably use the truck 60 percent highway and 40 percent city driving. I have been using 5w30 mobil 1 truck and suv. Should I go to 5w20 which is recommended?? If anyone has a comment (oil recommendation) on this motor besides it being a dog let me know!
