I have been running Valvoline Full Synthetic High Mileage in my vehicle . The price at Wal-Mart was about $26 for a 5 qt jug. The Valvoline Synthetic Blend High Mileage was always just about 3 dollars cheaper so I chose the full Synthetic. Well just was at Wal-Mart they have the Synthetic Blend High Mileage on Sale for $14.17 and the Full Synthetic High Mileage priced at $22.88. I am thinking of using the Blend and at that price as I am doing 5,000 oci and it is a 1996 Ford Taurus with less than 62K (Great car) I am also thinking of buying several jugs of both and then mixing myself the Full Synthetic with the Blend. I have 3 vehicles that all use 5W 30 Valvoline Full Synthetic HM. Just a thought . thanks
