0W-20 Advanced Fully Synthetic Motor Oil 5 Qts

Mobil 1 Advance Fully Synthetic oils are designed to help extend engine life in high mileage engines. These advanced full synthetic motor oils feature:
A proprietary blend of high-performance synthetic base oils that deliver up to 20,000 miles of proven protection
A boosted level of seal conditioner to protect engine seals because, over time, rubber seals can harden or shrink, resulting in oil leaks
If your engine contains excessive sludge deposits due to less-than-adequate maintenance practices, Mobil 1 High Mileage synthetic motor oil can help reduce this sludge. For severe cases of engine sludge, short oil change intervals (3,000-5,000 miles) are recommended for the first two or three oil changes as the sludge reduction takes place. (In cases of engine damage that may have resulted from poor maintenance, even Mobil 1 motor oil cannot remedy years of neglect.)
