I'm about to do another oil change on my 7M-GE, which has about 53-54k miles on it. I've been running Royal Purple 10W-30 for what I'm guessing to be around 6k-7k miles, I could be wrong, but it looks pretty dark in color. I put in a Wix napa oil filter when I did the change, so should I look at getting a new filter as well or should this one be good? BTW, this was my first "full synthetic" oil cycle, so I'm guessing yes?
