I second that. It's all about super tech, mobil1 and Pennzoil but valvoline produces great fuel mileage and smoothness every time I use it. Plus the oil stays nice and clean the whole interval. Outside of 1 change with PP 0-20, my wife's rogue has had nothing but 0-20 with max life for 25k. It's a leas but if I turn it in someones getting a well cared for vehicle.
