WOW. That's pretty cool. It cleans the oil right in your crankcase. That should save a few oil changes..
And it reminds me of a question that popped in my mind just before my vacation. Synthetic oil. Most new vehicles require synthetic oil in the oil changes or you will void the warranty. It's also called Dexos, which is a GM specification synthetic oil, and is the change for the future of oil changes in newer vehicles. So, I'm thinking there is going to be a ton of waste motor oil that is synthetic. I was wondering if anyone knew if synthetic oil can be burned in a multifuel engine, like normal waste motor oil. Not sure if it burns as hot, or hotter, or not at all.
