There was a recent thread about whether conventional oils have any advantages over synthetics. Seemed like a controversial topic but it got me thinking about VR-1, which Valvoline describes as a "conventional" oil but that still gets a lot of positive reviews, including on this forum.
Is there a specific advantage to, say, VR-1 10w30 conventional compared to a cheaper "synthetic" like, say, Mobil Super 10w30? Other than the flat tappet issue, is there any reason one would want to use the Valvoline conventional for a specific application instead of the Mobil synthetic or a comparable, inexpensive synthetic 10w30?
