On our school bus fleet the first cold day of -15 with the new fuel over half our fleet would not start even though they were plugged in. and when they did get them started they would run about ten minutes and then fuel lite come on and then shut down on the newer models. and older just stopped. they replace filters. would run for ten 15 minute and shut down again. this was the blended ultra low stuff with the additive. Long story short they had to blend more no# 1 into the mix and add a cetane booster. was a mess. they never had this much trouble before even down to 30 below so. I kind of believe it is more the the manufactures quality (low cetane numbers) Because the (ADDITIVE THAT DID THE TRICK IS THE ONE FOR THE CETANE) cetane rating was only testing around 38 to 40 now its at around 50 and all start right up and run like tops.
