How does anyone feel about Valvoline oil? I have always used the Duralube (I can't remember if that's right). The 1/2 synthetic if I remember right. My car has about 188,000 miles on it. I don't think using the full synthetic would do her any justic. Since 40,000 miles that's the oil that I have used. And I am sorry to say, I have also used the Fram oil filter, and yes, next oil change I will change over to the Mobil 1 as you guys think is the best.
Any opinions?
