Everyone knows the same ole Dino vs synthetic argument. Just had a thought. Why not take an old microwave oven, pour up a cup of Dino In a glass beaker, and heat for a set amount of time say 1 minute intervals and watch for the darkening and smell of burning oil. Do the same with synthetic. That should draw a conclusion if synthetic is really different than Dino. It's not scientific, but it may show some differences, or at least prove the time honored thought that synthetic can handle the heat better than Dino.
