10 W 30 Premium Oil Synthetic Blend

For general and extreme automotive use.



SKU: OG 2520-1 Category:


Our 10W-30 Premium Oil product has very consistent multiple viscosity required by today’s hi-tech engines and recommended for “classic” engines as well. Its blended formula includes synthetic agents that minimize oil drag while protecting internal engine metals, similar to heavier viscosity oils. 10W-30 is recommended and appropriate for use in minivans, passenger cars, SUV vehicles and light duty trucks. It’s also recommended for regular use in high-mileage, commercial delivery and similar service vehicles.

10W-30 provides exceptional wear protection, friction reduction, allows extended time before oil changes, provides increased cleanliness, improves fuel economy, enhances piston ring sealing for more power, high temperature capability, oxidation resistance and increases lubrication of hot metals. Its high “viscosity index” provides thicker, more consistent oil films for lubricating engine bearings, lifters and camshaft surfaces. When engines get hot, high temperatures can cause some engine oils to break down exposing the engine to excessive wear. Our engine oils are formulated and indexed to resist high-temperature affects, an important benefit when driving in hotter climates.

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.


OnGuard Engine Oil, Inc. does not warranty any of its products to be fit for any specific purposes, uses or applications. Each vehicle engine manufacturers’ published lubrication recommendations and/or the vehicle’s maintenance mechanic should be consulted and followed when selecting engine oil.
