I am trying to understand. Can someone describe the odor? The 216 in my truck doesn't stink beyond what I'd expect. The perfume is like a hot oil mixed with lube grease, maybe a hint of antifreeze, a bit of exhaust and nothing else. The perfume lasts just as long as it takes for the engine to cool down. Granted, my shop is away from the house. So, maybe my situation is different?
