Alex De nice truck,I had a 2013 Limited and lived it. Getting your oil changed at the dealer is fine. The synthetic bulk oil they use is as good as any you can buy yourself. Some people have a fixation on what a great oil is just like some think there's only one brand of gas to use because it has some kind of miracle formula. On my last four Ram 1500's from a 2009 to a 2015 I put about 130,000 on each one before getting another one every two years. They each went into the dealer at the end of every month for oil change at around 5500 miles and regular service. They never had any issues of any kind. I usually went through three sets of tires on each truck, I traded the 2015 for a new 2019 Laramie Sport 4x4 last January and today I only have 19,000 on it since I'm now retired. And it is also being service at the dealer.
