SWEPCO 306 Supreme Formula Engine Oil

  • Exceeds Requirements For Superior Soot Handling & Improved Performance In New EGR Engine Designs
  • Manufacturer Approved for Extended Drain Service

SWEPCO 306 Supreme Formula Engine Oil is a premium quality, multi-purpose, extended service engine oil specially formulated to provide superior performance under the most demanding operating conditions. Its multi-grade all-season formula means you can lubricate your entire fleet, even new engine designs, year-round, with SWEPCO 306. It provides outstanding wear control, service life, cleanliness, thermal stability and corrosion resistance for most diesel and gasoline engines. SWEPCO 306 is formulated from the very finest high VI 100% solvent refined paraffinic base stocks available and the most advanced additive chemistry, including DIMONYL®, SWEPCO’s proprietary anti-wear additive. Easier cold weather starting with less wear are additional benefits associated with SWEPCO multi-graded weights. Because SWEPCO Engine Oil provides superior performance for a longer period of time, SWEPCO 306 saves money through overall reduced lubrication costs, including fuel conservation, reduction of waste, reduced maintenance costs and extension of equipment and oil life.
