Dr HOM EPM (Extreme Performance) oils are formulated specifically for the rigorous demands and severe operating conditions of racing and extreme performance engine applications. These engine oil formulae represent the absolute state-of-the-art in formulation and additive chemistry, providing unmatched protection and performance no matter the type of racing. EPM engine oils are fortified with a high level of zinc / phosphorus anti-wear additive and a generous dose Tribology German. Tribology German is Dr HOM proprietary additive chemistry that greatly increases the protective film strength of the oil, reducing metal to metal contact, friction and wear. This unique and highly effective additive technology greatly enhances wear protection above and beyond that achievable in any other commercially available engine oil. Tribology German also increases the oil’s resistance to thermal degradation, enhancing lubrication at extreme engine temperatures, reducing deposit formation and lengthening the oil’s useful life.
