Last year… the Blue 20 Wt 3 in 1 oil got too cold in my CZ 22 lr it caused light strikes, EVERY Time. I did not feel it had too much lubricant on the firing pin assy. but it was gummy. Went back to the truck and flushed it out, ran fine. I’ve used Mobil 1 in cold weather and it works great. Also if you have a gun that fowls a lot try Mobil 1 compared to a strait mineral oil and you’ll see the M1 suspends crud from the cracks. Runs ARs clean
