Thank you for visiting our website. Before you start looking for the things that brought you here, I need to tell you about a problem that has recently surfaced. The oil companies are constantly reformulating their products to improve them and to meet new government regulations. The newest oils have the letters SM for gasoline engines and CJ for diesel engines - as of May 2007. These latest formulations contain reduced levels of Phosphorus and Zinc that were mandated by the US Government because of evidence that high levels of P and Zn damage catalytic converters. The problem arises for owners of older cars. If you are caring for a car made before approx. 1995 you may have increased wear on some internal engine components if using these newer oil formulations. One solution has been to add Zn and P back to the oil using an additive such as GM's EOS Engine Oil Supplement at every oil change. In addition, it appears Boron is a good alternative to Zn and P. With the high cost of engine rebuilds, it may make sense to risk damage to a catalytic converter rather than destroy an engine. Naturally, more study is needed on this important subject. I plan to update this part of my website as more information becomes available.
