Mr Dz Sales & Services Crest Hill IL 60403   Phone: 815-274-9133   Welcome to Mr Dz Sales & Service Featuring AMSOIL As you can see we enjoy Motorcycles here. With the use of AMSOIL's Superior Products, long road trips by motorcycle, van or RV are made easier to enjoy with out the need to look for a service facillity in the middle of a 6,000 mile road trip to change the motor oil of a Highly Advertised Competitor. As many of us have come to be VERY SATISFIED with AMSOIL's High quality products so will you!! I don't let the manufactures terrorize me with their scare tactics, that I need to change the motor oil every 3,000 miles or the Warranty will be voided. In the past five years many of the auto and motorcycle manufactures are recommending oil changes at 4,000 miles or longer. I'm here to support my family, not some greedy oil company that sells low quality motor oil at inflated prices.   Corporate Announcement AMSOIL Signature Series 0W-30 Synthetic Motor Oil is the industry benchmark in lubrication technology.
