MPG drop after oil change
Got an oil change 2 days ago and I’ve noticed a significant drop in mpg. It is about a 5-6 mpg drop. The truck is a 2024 1500 3.0. I’m concerned they put the wrong oil in. It’s been about 200 miles and the oil is already jet black. This is my first diesel so I’m not sure how common this is. Should I change the oil again or could it be something else?
