New from Rislone is an Engine Oil Supplement with Zinc Treatment, which can be added to the oil in vintage Mustangs to restore ZDDP levels to prevent damage and wear to the camshaft and valvetrain.
Because engines in vintage Mustangs use flat-tappet camshafts, they need ZDDP, a zinc and phosphorus oil additive that has been drastically reduced in modern engine oil formulations.
Designed for engines that require SL/CI rated oil and earlier, Rislone Engine Oil Supplement with Zinc Treatment works with all petroleum-based motor oils, including conventional, high-mileage and synthetic formulas. For best protection, it should be added at every oil change. It can also be used to top off oil as needed to improve engine protection.
Rislone Engine Oil Supplement with Zinc Treatment is sold in leading automotive supply stores across North America. For more information, call 800/345-6572 or visit the website at www.rislone.com.
