Just got a new 2015 FE 350. Manual says basically go easy on it for the first few hours. As far as oil change it says change after 1 hour, then 3 hours then every 15 hours. What is the significance of the 1 hour change? Some guys say you can go 200-300 miles before the first change. I like to stick by the manual and my thought is if they tell you to do something it must be for a reason.
