"Mobil 1
Mobil 1 Annual Protection has been formulated to be the top performer in the Mobil 1 line, offering our longest guaranteed engine protection of 1 year or 20,000 miles, whichever comes first, which is 5000 miles beyond the level guaranteed by Mobil 1 Extended Performance. While this may not initially sound like a significant increase, the overall performance increase required of an engine oil to go from 15,000 mile to 20,000 mile oil change intervals is very challenging. The development of Mobil 1 Annual Protection necessitated a new ultimate synthetic engine oil, formulated with specially selected synthetic base stocks combined with an additive boost to resist oil breakdown and provide unsurpassed wear protection. This high performance formulation not only provides outstanding engine protection for 1 year or 20,000 miles, it also provides excellent protection in severe operating conditions like towing/hauling, hot stop ‘n go city driving and turbo charged engines. When you select Mobil 1 Annual Protection, you’re selecting our best and can count on our highest level of overall protection"
