There is so much research out there showing 5w30 with lower viscosity protecting turbo engines very well. Changing the oil is more important. As long as your doing an OCI of 5,000 or less, any 5w30 will protect a turbo.
I looked at the thread...I don't get it. What does it show that keeps Valvoline on the avoid list? What was the experience you are referencing? It isn't EP either, his thread is about Valvoline Restore and Protect.
Hey, Gents!
I recently went with Valvoline Advanced 5w30 for my last oil change with dealer under warranty.
So, in 5,000 miles, I will be out of warranty and I will be doing oil changes myself at home. OCI will stay 5,000 miles, but I am wondering which of these oils will best for year round...
3.5 EcoBoost.
Only two choices: Valvoline Advanced 5w30 or Quaker State Ultimate Protection 5w30. Total oil change would have a $4 difference between the two, so the price is negligible.
Which one and why?
