I'm happy to hear it's working for youNope. My car has been "meticulously maintained" and with 20,000 miles on the clock, still showed particles of carbon in the oil filter after running Valvoline Restore and Protect. It also cleaned the top side a bit (it wasn't "dirty) and made the engine run quieter.
Valvoline Restore and Protect is a winner all the way around.
As I said before, if Valvoline Restore and Protect is available to me for $60 per jug, and Mobil 1 0W-40 for $33, I'll run the higher HTHS euro oil every time.
I'm not thrifty either, none of my vehicles see more than 5,000kms per year so the oil that comes out of them once a year is barely discoloured. I'm just not willing to pay twice the price for cleaning when the oil I use is touted as one of the most detergent dense oils going, along with being one of the most robust.
