Mobil 1 fan here chimng in, switched to Penzoil full synthetic after I let the dealer do the first oil change. I installed a K&N oil filter along with 7 qts of the 5w-20 Penzoil synthetic. 1300 miles later I am still happy with this oil. It's much cleaner looking than the Penzoil dino oil the dealers use. It reduced a lot of engine valvetrain noise & vibration as well. If this oil turns black before the 6k miles mark, its getting changed period.. I don't like when the oil gets dark, it just scares me. Mobil one always went 5-7k and still looked like it just came out the bottle, even on engines with 100k miles. Hopefully the Penzoil will give the same long term results. So far I am very happy. My dad and I used to joke that Mobil 1 syn. "made" oil, and not caused the engine to burn it. We always seemed to get the same amount or more we put in when we drained the old oil.
