We'd like to clear up some confusion. There are many websites on the Internet that use business names similar to ours.
Auto-Rx® Worldwide, Inc. only sells one product and that product is Auto-Rx® Plus. If it does not say Auto-Rx® ( look for the hyphen ) it is not our product.
Modern Engine Design:
Modern engine designs have incorporated aluminum blocks and heads for many years. However, the actual working parts of the motor are hardened steel. This includes crank shafts and camshafts. Pistons are made of aluminum, but the piston rings are made from steel.
Auto-Rx® Plus sees an aluminum motor no differently than a cast iron block. Auto-Rx® works perfectly fine in aluminum motors. That is 99% of the Auto-Rx® Plus business.
