ZMAX micro-lubricant soaks into an engine's fuel and metal, expelling carbon and other harmful deposits, to increase gas mileage, performance, horsepower, and engine life and to decrease harmful emissions. ZMAX begins as pure micro-lubricant. A proprietary process reformulates it (altering the molecular structure) to create molecules far smaller than those of conventional motor oil.

Both easy-to-use treatments are 12 oz, and they do not replace regular oil. ZMAX is recommended every 6 months or 6,000 miles, using ZMAX will not overfill a normal oil level because it soaks into metal. By properly replenishing ZMAX, an engine receives constant protection.
