So Friday night I decided to change the edge SN black jug 5w20 garbage out of the Focus as it was getting kinda klacky like valve train noisy with it. Following some knowledgeable members advice to try PYB; I put some PYB 5w20 in. After a day of driving over 65 miles total, the valve train noisy ness is GONE. Here on out in my fleet it will be QSGB or PYB
