been using Valvoline high mileage for 15000km now and the oil consumption went down from 1500km per liter to 2200km per litre. My V6 has done over 182,000km now. Seems ok and probably worth the slight extra cost.

My CR went from a 189 average to a 198 average. Not a huge difference but it helped, and I can feel a slight difference.

is your car smoking a lot?
otherwise I think the valves seals needs to be replaced.
