I just turned 800 miles. As this is my first CTD, how far did you go before the first oil change? With all the other stuff I have had new, I usually go about 500 or 600 miles, before changing the oil. (and filter)
That varies widely and the first message is often too early. The computer uses time, mileage and style of driving to decide when to post the Oil Change Required message. In my case it came on at 1200 miles. The reason was because the build date of the vehicle was Feb. 07 but I purchased it new in Sept. 07. The message was primarly because of time. There are no sensors in the oil itself as some of thought.Ram3500Dually said:At between 2000 and 3000 miles your truck will TELL you to change the oil. I would wait till the message comes up.
