My 13 started reporting a need for an oil change at around 1500 miles. I thought, "NO WAY!", but I had it changed at the local dealer anyway as I was about to drive from CA to OH with stops going and returning. That was in July 2015. In October 2015, I made another trip cross country to FL and return via a CO. The idiot light came on again on the return trip. I went to a Ford dealer on Aurora/Colorado Springs. The informed me that I was running the wrong oil and not enough oil with the BOSS intake system mod. In short order, I was back on the road and had no more problems. Also, about that same time, I had started hearing a scrunching sound. That was solved with a lube job.
