SWEPCO 306 Supreme Formula Engine Oil
SWEPCO 306 Supreme Formula Engine Oil is ideal for classic, vintage and legacy vehicles with diesel or gasoline engines. It remains one of our mostly used engine oils and a recommendation our Field Service Representatives and Distributors make on a daily basis. SWEPCO 306 was originally formulated for the Tier 1 2002 to 2007 over the road diesel engines and 2004 to 2010 off road diesel engines. These engines could burn 500 PPM sulfur fuel and are prior to most of today’s exhaust treatments. SWEPCO 306 meets or exceeds API CI-4+ and SL/M specifications along with all other major engine manufacturer specifications prior to 2010.
The exceptional anti-wear properties of SWEPCO 306 Supreme Formula Engine Oil fight against friction, heat and wear making it well suited for older equipment and engines. SWEPCO 306 performs well in off-road, racing and classic engines and provides maximum protection against scuffing, sludge, soot, corrosion, rust, shearing, high temperature thinning and low temperature thickening in both gasoline and diesel engines.
Many older engines and seals were designed to use mineral oil-based engine oils rather than synthetics and synthetic blends that are commonly used today. SWEPCO 306 is a high-performance mineral oil-based engine oil that is compatible with seals and materials that are original equipment or rebuilds.
