I gotta give the place 2 stars because the staff is extremely nice. If that weren't the case I'd give this place 1 star because of their lack of knowledge.
I have a 2008 6.4L diesel and it calls for 15W-40 in hot AZ weather. Newer ford diesels call for 10W-30. I should've checked to see they put in the right oil but when my wrench light came on and read a p012f DTC I knew immediately they put too light of oil in.
