I bought a 2011 lexus is250 from a dealer about a year ago with 48k miles on it and I am looking towards getting my first oil change from the dealers. I did some research and some people say that you get the first oil change is free and I was wondering if that's true for my case. Another question is what type of engine oil does the Is250 use and should I use synthetic oil? *Im a new car owner*
