“I have a 1999 ford 7.3 that is the worst to start up when it’’s cold. I have to leave it plugged in if I’’m going to leave for more than 10 hours cause it will not start EVEN WITH STARTING FLUID!!! My friend told me to try Diesel 911 so today i had no other options. i drained my fuel filter and put 911 in and it started right up. I will start using this stuff all the time in the winter. THANK YOU!”
