About Our Formulas

Our lubricants are formulated and designed to include synthetic components that help provide more consistent viscosities, benefiting today’s high-tech engines and “classic” engines as well. OnGuard formulas always include state-of-the-art synthetic lubricating agents that are far better for engines than conventional oils to reduce bearing loads, oil drag, oil contamination and unnecessary power losses. OnGuard formulations protect internal engine metals while improving power and mileage. OnGuard Engine Oils are an excellent choice for on-the-highway vehicles, providing both oil and fuel mileage enhancement. This also applies to off-road vehicles and severe racing applications. OnGuard Engine Oil products are compatible with all conventional oils and synthetic engine oils.
