U.S. Price Adjustment Effective Aug. 1
"After holding the line on pricing in the U.S. for the past five years, we are forced to implement a minimal price adjustment effective Aug. 1. The costs of base oils and other raw materials have increased significantly in the past few months, while the costs of every aspect of manufacturing and distribution have increased over the past five years. The accumulation of those increased costs requires an average price increase of 6 percent on many AMSOIL products. The renewed strength of the Canadian dollar and relative stability of the exchange rate has allowed us to leave Canadian pricing as it stands."
