"I started using AMSOIL in the spring of 1983. Using AMSOIL SAE 30 Diesel Oil and the AMSOIL By-Pass Oil Filter, we run 900 hours between oil changes on the 160 PH Case and 700 hours in our 120 HP Deutz Allis air-cooled. I used the AMSOIL 20W-50 Synthetic Oil in my Massey 510 combine on a 2-year oil change schedule. I am very pleased I was introduced to AMSOIL Products."

I used AMSOIL Synthetic Engine Oil, Synthetic Multi-Purpose Hydraulc Fluid, and the AMSOIL 80W-90 Synthetic Gear Lube in my two Deere tractors, my 855 Steiger, and my N6 Allis combine. I also use the AMSOIL By-Pass Oil Filters and change oil once a year. Our farm uses nothing but AMSOIL and we are happy with the results. There is a large difference in performance between petroleum oil and AMSOIL, as well as a lot of money and time saved.

I started using AMSOIL in 1975, and right off I could see the difference, so I put it in everything on the farm. I use AMSOIL 10W-40 Synthetic Oil in my 6 tractors -- 3 Internationals and 3 John Deeres -- and in my Massey combine. We use the AMSOIL 15W-40 in our two semis, a Mack and a Detroit engine, along with the related AMSOIL Synthetic Lubes in the transmissions and differentials. AMSOIL 75W-90 Gear Lube is in the irrigation gear heads and this has lowered the fluid temperatures considerably. We are 100% AMSOIL and plan on staying that way.

The AMSOIL Multi-Purpose Synthetic Tractor Transmission and Hydraulic Fluid has not been changed in our two large tractors since installing it in 1982. One of our irrigation engines runs all year with no oil change using AMSOIL and the AMSOIL By-Pass Oil Filter. AMSOIL 75W-90 Synthetic Gear Lube is used in the gear heads on a 5-year change period. My records show that I'm saving 58 cents on the dollar on lube cost between the cost of AMSOIL and petroleum lubes.

We have been using AMSOIL totally since 1974. We farm separately but do, on occasion, interchange some machinery. Between us we have four large 4-wheel drive John Deere tractors from 200 to 400 HP. We use AMSOIL in all the tractors and the combine, and the AMSOIL By-Pass Filters, too. We change oil once a year in the early spring. We have not figured our real savings by using AMSOIL, but for sure it's a strong 50 cents on the dollar over petroleum oil, and saving a lot of labor on very little downtime. There is no way we could afford to go back to petroleum, even if it was given to us free.
