TRUEGARD 5W-20 synthetic motor oil in a 55-gallon drum is a must-have for medium and large-scale operations. Its extreme protective properties can keep engines from seizing under tough conditions, and because it lubricates quickly, it’s ideal for cold temperatures and rough driving. At Keller-Heartt, we specialize in connecting our customers with API SN and GF5 certified motor oils; that’s why we’re proud to carry TRUEGARD 5W-20 synthetic motor oil.
