Cleaner engines last longer and run better. Visco’s CleanGuard™ engine protection technology keeps your engine cleaner and fights all dirt, varnish and even deadly sludge in vital oil ways. Visco’s components slow the formation of dirt at its source and wrap up dirt particles so they will not stick to critical engine components.

A premium mineral engine oil with thermal protection formula that keeps engine running cleaner. Today’s engines run hotter and harder than ever before. High temperatures in the engine lead to oil oxidation and thickening. These engines need more than ordinary oils to keep them protected. Thermal Guard is an engine oil technology that slows down oil thickening due to heat and enables the oil to flow freely to critical engine parts.
