We're not just an AMSOIL distributor, we know the products and how to use them! Owner Roger Spanske has been with AMSOIL since 1996 and attends AMSOIL university each year to ensure he has the latest information and research on the many products available. He has over 25 years of experience in the trucking and automotive industry, with expertise in diesel trucks and over the road semi trucks.

Roger is a T-1 Certified Dealer, meaning AMSOIL acknowledges that he has an understanding of all the business workings and recommends him to any interested persons locally.

We carry some inventory at our shop to accomodate our customers needs. In addition, Roger can do maintenance and product changeovers for customers who don't want to do that themselves.

I have been using Amsoil products for years. It all started when the transmission burned up in my vehicle that I was driving at the time. An engineer friend suggested I switch to Amsoil because they did numerous tests and the end result showed it was the best product on the market. The manufacturer did not want to recommend Amsoil products due to the fact the transmissions were lasting longer than normally expected.

I decided to become a dealer because the quality and standards are so high. Personal experience has shown I can sell a product I believe in so strongly and have the proof of not only personal use, but that of the satisfaction of all my customers.

My experiences include well over 25 years of driving semi trucks while using Amsoil products. For years I have also used Amsoil products in my snowmobiles, boats, lawn equipment and personal vehicles.

Amsoil products are an easy sell when you personally experience such quality results.

Sincerely,
Roger Spanske
