Hi,
Just purchased a 1988 Dodge B250 Conversion Van with a 318 motor and 130k miles. I am receiving it tomorrow and plan on replacing all the fluids within the vehicle. My question is I believe the book calls for 10w30 but I planned on using a valvoline high mileage oil. Should I stay with 10w30 or up it to the 10w40. The car will be parked all winter in storage until the spring if that matters at all. Thanks
