Thanks for the support Bill, The reason for my statement was in the last year I watched Tim over at well...lets just say a well known toyota engine rebuilder, deny two claims due to the owners firing up their engines loaded with synthetic oils. Regardless though....having to wait for rings to seal is an inconvenience but the real danger with synthetics at break-in is the rings not sealing at all due to glazing. We're talking Toyota here...nothing close to what takes place in a corvette engine at initial firing.
