<x-charset UTF-8>This sounds very much like what happened to me 15 years ago... and 350 miles later my engine was destroyed. At least your running full flow, but since your engine runs hotter and has lower oil pressure why would you stick with the synthetic? 1776 runs too hot anyway. I dont know why this doenst happen to everybody using synth... but Im not the only one who lunched an engine with it.
