We have been using 502 Soluble Oil for all of our cuttin, machining, and pressure drilling applications for several years. We like it because it works and we can use one product for all of our cutting oil needs. We are in the process of expanding our manufacturing facility by 22,000 square feet, and Troco's 502 Soluble Oil will continue to be an invaluable part of our future.

Interesting you ask about our experience with Calcium Sulfonate grease. As the Cat dealer in the coal mining area of Appalachia, we have been supplying bulk calcium sulfonate grease to our customers for over ten years now. The first bulk customer we had did it at first because he reduced his grease consumption by 24% as measured and reported by him. Then Cat offered better warranty terms on large loader pins. IF a customer used calcium sulfonate grease on a 992 with an auto lube system, Cat would warranty the pins for 10,000 hours. We did not have one warranty claim from those customers using the calcium sulfonate greases in the ten years the program was ongoing. Most recently, we had a large mining customer with a Komatsu PC5500 shovel. He was having to replace the pins in the large excavator once to twice a year. July of 2013 will be the third year he has been using our grease and is yet to have a failure of a pin on either of his PC 5500 shovels. Calcium Sulfonate greases offer some of the best value out there for a mining or construction operator. When you ask a Cat dealer what grease you should use for “Extreme Service”, they will tell you either a synthetic grease or calcium sulfonate grease. The calcium sulfonate offers the best value without a doubt. If you have anyone that is doubtful on calcium sulfonate greases, have them contact me and I can tell them more.

I would like to take the time to personally thank the team at Royal MFG / Wright Oil for helping us with our switch to synthetic oils and extended service drain intervals. This has been instrumental in many ways by helping us improve the efficiency of our operation and reducing our overall cost of maintenance. They have also been involved with oil sample testing on our fleet to ensure reliability and sustainability was delivered. Thanks again!

Thank you for your help in getting some information sent over to Mr. Rocamontes at Leo’s Truck service. He was extremely pleased with the way the rod and main bearings came out on my truck after 1,012,000 miles on it. I told him I had been using the same oil since I bought the truck in 2007 with 350,000 miles. This is my third truck that I have driven over a million miles running the same oil with no break downs due to poor lubrication. I have been using the 20W/50 diesel super supreme plus for the last 14 years as well as the 10W/40 blend for my personal vehicles and am extremely pleased. I have recommended it to all my trade friends and have successfully converted them to the Royal Manufacturing brands.

Steve Fryar PF&E Oil Company
We have been an ADC for Royal Manufacturing / Wright Oil Company over 7 years. The expertise of producing the highest quality lubricants and greases coupled with great pricing enables us to be extremely competitive in a very tough market. The vast majority of our customers have changed from Delo, Shell, Castrol, etc. and are now Wright Oil users. Some changed due to pricing alone while others recognize the superior additive package in the Wright Oil. We use Wright Oil and grease exclusively in our company fleet of trucks and my personal vehicles.
Charlie A. Lile True Transport, Inc.
True Transport has used the products listed below for over 5 years. • Royal Diesel Supreme 15w-40 Ultra CJ-4 • Royal Ultra 865 Marine Grease • Royal Diesel Supreme Plus-SAE 40w We are very satisfied with these products and their consistent performance in our 18 wheelers. The Royal Ultra 865 Grease has real staying power with its great lubrication and anti-corrosion properties that we need in the Gulf Coast region. Also, after switching to Royal Oil from Shell Rotella T, our consumption dropped considerably. We also appreciate the good service we receive from Kapalua Fuel and Marine out of Corpus Christi, Texas.
