Yesterday I went out in the garage to grab my gas can to get filled in case I need it for my snow blower. I usually put a splash of carb cleaner and MMO in the can to treat the gas ahead of time. When I picked up the MMO, the bottle fractured into plastic shards in my hand. I didn't even try to twist the cap off yet. It's been in the 20's for the last 2 days or so, but I've never had this happen before. The bottle was about 1/2 full, so I had 16 oz's of MMO leaking thru my fingers with nothing handy to try and put the rest of it in.So now my garage smells like a combination of oil with a hint of mint.So be careful handling plastic bottles left out in the cold.,,,
