Synthetic Oil vs. Conventional Oil

The benefits are clear

Conventional oil cannot stand up to synthetic when it comes to longevity and ability to handle extreme high temperatures without breaking down. Synthetic oil molecules are formulated to be uniform giving synthetic oil based lubricants exceptional properties and consistencies at both high and low engine temperatures. Their composition is much cleaner, and has a lower volatility and therefore do not vaporize out the exhaust as quickly.

Synthetics can last as much as three times longer than conventional oil, and have been shown to produce less resistance in the engine and therefore offer more horsepower and overall efficiency for the engine. A synthetic oil blend mixes the two together to give you moderately better motor oil at better cost to you.

Premium Quality

OnGuard Engine Oil products are very high quality, synthetic based formulations. Our products are rated at the top of the ILSAC Specifications Index which sets standards for classifying engine lubricants. The highest rating is API SNGF-5 which all our motor oil products meet or exceed. Onguard produces the best synthetic oil on the market.


API SNGF-5 is the Industry Standard for Our Motor Oil

In 2010 the American Petroleum Institute (API) introduced a new engine oil category called API SN and a new supplemental category called Resource Conserving.

The API SN category is an improvement in the following areas: high temperature deposit protection for pistons, better sludge control, better seal compatibility and aftertreatment compatibility.

The comparison is like this:
