best oil on the market broke a serpentine belt that stopped the water pump from work she drove it tacked on temp hand red lined for about 5 minutes no other oil would have held motor from blowing 2nd on list is Valvoline. But lasting 20000 miles it's stupid to not pay few more $ even tho I'd change it around 15000 miles motor runs like a top looks brand new inside with 262,000 miles on the car winter I run 5w20 summer 5w30

My Mobil1 savior message

My 2014 Ford Taurus Limited with the 3.5L has lived its hole life using Mobil 1 5W20, and at 137,000 it's purring like a kitten. Change my own oil and use the Mobil 1 oil filter every 5,000 miles, and when it's ready for an oil change, my dip stick still reads FULL. New cars can't match that record!
