"Auto-Rx is going to give you a better
opportunity to lower your monthly car maintenance and give you better than even chance to increase your MPG."
Why ? "Because the gold standard is that all engines should have a pressure of 10 PSI for every 1,000 RPM of operation, not more, not less.
After all, you do need some pressure to move that oil along, but only enough pressure, not more. More pressure is not better, it can only result from the impedance of oil flow. Remember that oil flow is the only thing that does the lubricating.
