Mike at Monster Diesel was very helpful and did a great job finding the low power issue on my 6.4l Ford, complete vehicle inspection, and oil change. We were on vacation, from out of town, and took a chance by choosing his business, based on previous reviews of other customers. Simply stated, Monster Diesel knows what they are doing and how to treat customers professionally, efficiently, and with honesty. I would recommend you give them an opportunity to earn your business and respect too! Well done, Thanks. - Keith I. (5 star review on Google)
