Should I use synthetic oil?
I bought my first Jeep last October and pretty much loving it other than a few things I have to keep taking it back to the dealer for, but that's a different topic. I'm trying to learn the do-it-yourself basics because I don't trust my mechanic since he blatantly lied to my face about changing the oil the last time. My friend gave me a crash course in changing oil and I was just wondering, is there a benefit to using synthetic oil? I'm told royal purple is a kick *** oil to use, but I'm also told once I use synthetic I must only use synthetic. Also, for oil filters, does it matter what kind? I used Fram last time, but I notice K&N has an oil filter also, and I'm told that it is also a great brand. Any information would be greatly appreciated! I drive a 2011 Jeep Compass 2x4 by the way.
