The Traveller 55 gal. 5W-30 Full Synthetic Motor Oil is formulated for resistance to sludge formation and varnish deposits during stop-and-go driving and maintains outstanding wear protection under severe driving conditions. The 100% synthetic base oils provide exceptional resistance to high temperature oxidation thickening. Sophisticated additives prevent sludge formation commonly caused by moisture and combustion by-products. The exceptionally high viscosity index minimizes cold weather oil thickening, which greatly reduces battery drain and engine wear, even at subzero start-ups. This motor oil comes in a 55 gal. drum.
