Well Valvoline is $1.43 and is not any better then $.84 cent Walmart oil. You can buy Chevron Supreme for $1.08 and it blows Valvoline out of the water in terms of UOA and addative package per $$$ I can not see paying a premium for non-premium oil! FOr the same price as Valvoline you can buy Delvac 1300 or Delo 400 and both are much beter then Valveline! It meets the reguirments but it sure does not exceed them!
