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

Simply the Best

I've been using Mobil One Full Synthetic Extended Performance Motor Oil in 4 different vehicles for many years now. The blend of 8 additives keeps engines clean , reduces friction and wear, and protects gaskets from failure. paired with Mobil One Full Synthetic Extended Performance Oil Filters I get 10,000 miles between oil changes. Walmart seems to always have the lowest prices available.

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!
