Recent Review: It went well. The gentleman who performed the review was very thorough and very helpful. However, due to the cost we did not award the contract to Superior. They were about $1800 high. However, with regard to our experience with Superior, they have been our oil supplier for years. They also have provided annual maintenance and service for the same amount of years (about 40) and we have had no complaints whatsoever. They were previously known as Montour Oil Service Co.
