I have recently bought about 20 quarts of the Valvoline Syn power 5w30 from AAP for the BOGO. I had previously bought another 30-40 quarts last time it was BOGO. What is the general consensus on the board about this oil. I have yet to have a used oil analysis on this car (2006 Mustang GT 45,000 miles). It has has everything from Mobil 1 to RP in it. All have been synthetic, oil changes usually around 5000 miles. There really isn't a large amount of used oil analysis on this oil. I saw an awesome used oil analysis on a Crown Vic with synpower 5w20 and since these engines are similar in materials used to contructe them, I figured that the synpower would be a good choice.
