The Traveller 5 qt. Full Synthetic SAE 5W-20 Motor Oil is an advanced technology synthetic motor oil which provides high levels of engine protection, even under the most severe operating conditions. The 100% synthetic base oils in this Traveller motor oil provide exceptional resistance to high temperature oxidation thickening. Sophisticated additives prevent sludge formation commonly caused by moisture and combustion by-products. Exceptionally high viscosity index minimizes cold weather oil thickening, which greatly reduces battery drain and engine wear, even at subzero start-ups. This full synthetic motor oil comes in a 5 qt. container.
