Gentlemen in- the- know: Last summer, had my oil changed on my 2010 3500 coming home from a cross country trip and the tech guy (Wall Mart in Cody WY.) reset my oil change indicator to 5,000 mi. instead of keeping it at Ram spec of 7500 mi. How can I get it back to factory spec?? Read an archived post that solved this problem for a 2017 model, but no work for this 2010.
Any help would be appreciated.
