Heres the thing, the smell of my clothes after riding makes Mama sick and gives her a headache. I have a buddy who's wife is the same way, she gets a terrible head ache too if he brings his clothes in after a ride. She only mentioned it once, and never complains, but still gets the serious head aches. I switched from Yama lube to Penziol. The smoke has gone away considerably, but the stink is just as bad. I want an oil that has little to no stink, cost is no issue. We don't get enough snow here anymore so 4 gallons will last me a long time. tell me what ya think. Thanks Maxdlx ps if you are a dealer of your favorite stink free oil, shoot me a price per gallon and per case
