I'm a mechanical engineer and pretty decent under the hood of a car. Recently I bought a Ford with the 6.0L powerstroke diesel. After some googling - I decided to check out Precision Auto and I was very happy with what I found. They have the experience I was looking for and clearly know what they are doing. I also got the impression they run a clean, honest, hard working business so I'm not worried they're gonna waste my time. I would recommend them to anyone in sacramento looking for advice or service on diesel trucks.Reply: Thank you Thomas! It was wonderful to meet you and talk with you about your fascinating line of work! We hope to see you and your diesel in the future and appreciate your trust in us.
