*I've yet to see a virgin oil analysis of the new Valvoline Advanced 5W30 SP rated - I know ArcoGraphite and others here feel the former SN rated with it's Titanium content and low level of VII's may be the bet available synthetic you can readily find off the shelf at WM , etc. The former SN rated had a touch high ash content - if everything else remains close to the same , the new SP rated should be even lower in ash content that would make this oil even more of a winner (especially for GDI engine owners) ... Your thoughts on the new Valvoline Advanced 5W30 SP rated oil ?
