Fifty years ago, my dad sold BG products for Park’s Distributing Company in Charlotte, NC. I used to see how the products worked first hand. He had a 302 small block engine on a trailer and the oil pan hand windows on it. There was a valve on the drain pan. We would add BG MOA® to the engine, start it, and let it come up to operating temperature, then open the valve to drain all the oil out. Then, we would crank the RPM to high and let the engine run! We did this for over 8 hours one time, and the temperature never climbed above normal. Therefore, if MOA was that good, all the rest had to be good!
