Relyant® Synthetic Blend Premium Passenger Car Motor Oils are formulated to provide engine protection under severe operating conditions. They are blended from highly refined hydroprocessed mineral oils and synthetic base stocks, compounded to provide outstanding protection against wear and corrosion, prevent oxidative thickening and inhibit promotion of engine acids, sludge and varnish deposits. These multi-grades may be used over a very wide temperature range to permit easier cold weather starting and help minimize engine friction at start-up. They also provide added protection at higher than normal engine operating temperatures.
