I bought a 2005 V6 Mustang and I have changed the oil for the first time yesterday. I don't know much about oil so I just took it to Wal-Mart and got the Pennzoil 10W30 bulk. I wanted to get synthetic, but I didn't know what kind of oil was in there before so the guy at Wal-Mart said that since 10W30 is on the fuel cap the oil must not be synthetic and that I needed to get the regular oil. They said I would have to goto a shop to get my engine drained if I wanted synthetic oil. However, before going in for the oil change I noticed that my fuel filter was Motorcraft, which I later found out is a performace filter. Anyways, after changing the oil I noticed that the car is not as responsive as before.
So what should I do in this case? Does the type of oil have an effect on performace of the car, or could it be just me?
Thanks,
Igor
