How does Rislone Engine Oil Supplement with Zinc (ZDDP) Treatment work?

Zinc Treatment cools and lubricates the moving parts in your engine better then oil alone. The clinging properties hold the oil to metal parts preventing wear and dry starts. Special additives also prevent oil thinning at high temperatures where normal oil fails. The ZDDP creates the sacrificial layer on components where metal to metal contact happens preventing the metal itself from being worn.

What is ZDDP?

ZDDP, also called ZDP, is short for zinc dialkyldithiophosphate, is basically a combination of zinc and phosphorus. When put under pressure, like between a flat tappet camshaft and a lifter, it attaches to the metal surface and becomes a sacrificial wear material. Beyond being an anti-wear additive, it also is a corrosion inhibitor.

Questions to Ask Yourself:

  • Do I want to increase my engine life, but don’t want to brake the bank doing it?
  • Do I have the time and money for an expensive mechanic to tune up my car?
  • Many products claim to protect your engine, but at Rislone we’ve spent nearly a century proving it!
