Happy Thanksgiving. I finally got the new F-350 I ordered back in September of last year. This is my first pickup and first diesel. I usually break in all of my gas vehicles and do the first oil change at 1k and then again at 5k to flush everything out. Is this necessary on a diesel? I know it can’t hurt but I’m just curious on everyones thoughts about this. Also, Advance Auto has Mobil Delvac Extreme 10W-30 on sale. Is this a good oil for this engine? I will not be towing heavy but I will make trips to the Home Depot and long road trips to Florida with cargo in the bed. This is more of a toy for me than a work truck.
