SLS Associates is an independent dealer and supplier of AMSOIL Products.
AMSOIL Inc. located in Superior, WI is the leader in the research, development and production of premium quality, long life synthetic lubricants. In 1972 they introduced the world to the first API Certified Synthetic Motor Oil. At a time when 3,500 miles was considered an "extended" drain interval, the AMSOIL API SE 10w40 Synthetic Motor Oil carried a drain interval recommendation of up to 25,000 miles or 1 year, whichever came first. That was more than 8 times the standard oil change interval of the time. It is still the recommendation on the AMSOIL Signature Series Motor Oils. Since 1972, AMSOIL has gone on to develop one of the most complete lines of high quality synthetic oils, greases, gear lubricants, compressor and hydraulic fluids along with filters, filter systems and related items. In addition to their own line of premium oil filters covering over 90% of the vehicles on the road, they have partnered with Donaldson, Mann, and Wix to provide filters for applications not covered by AMSOIL Filters. This makes them the largest single source filter supplier in the world. In addition, the ALTRUM Division has nutritional supplements which help promote better health. This makes AMSOIL products the Right Environmental Choice for our vehicles & equipment and our personal health. If you would like more information on the AMSOIL Products use the Menu Bar above.
