Getting the old lady's '14 Dodge Caravan ready for her annual trip to California/relatives. As I mentioned in other posts this vehicle has the MS-6395 requirement which I use a loose reference. The last change about 5k miles ago used Valvoline Semisyn High mileage 5W30 that does meet the spec although the van owners manual and fill cap show a 5W20 fill. I have mostly ignored that over the years with 5W30. I have some gallons of Valvoline Euro III 504/507 5W30 on the shelf already. I will be heading to walmart later today so I can easily enough buy another jug of the Hi-Mileage semisyn Valvoline. I have taken to using the Fram synthetic filters because they don't rearrange their pleats like the cellulose filters do. Soooo what say you? Hi Mileage or Diesel oil this go round?
