While back I changed my PCV valve and started using Maxlife to see if that would slow down the oil consumption in my Rav. It did and I than dumped in some Havoline on the next oil change to see if it would go back to using oil.--Well it has, not at the same rate, but I will be going back to Maxlife on next oil change (not that Havoline is a bad oil). Changing the PCV valve I think did have an affect also, but Valvoline MaxLife does the job in slowing down the oil consumption for the Rav.
