Wanted to try something fun, exciting and robust in my poor Yaris that gets driven harder than it should this summer. After perusing the oil wall at Advance Auto Parts, the only thing that stuck out was the VR1 now in a 10w30 grade API SL. I read on the bottle the oil is Sapphire Blue - is this to appeal to the RP guys whom think they get something special when the oil is dyed? Anywho, I hope this runs better than the current fill of Valvoline 10w-30 API SM syn - I was somewhat non-plused over it's on the road performance and I had to amend it with M1 racing 4T syn to get the engine to rev smooth. This may go in the sump tamale. Any caveats?
