I have a 2001 Ultra classic with 20,000 klm's and I have always used th mobil synthetic and a friend of mine has a 2002 softail with the same amount of KLM's , he noticed one day riding that mine was running a lot cooler I then suggested to run mobil synthetic , my question is , Is it too late for him to switch , he has been running the HD 20-50 , I dont want him to wreck nothing and then point fingers at the oil.......We run in 100 plus tempatures here in venezuela.........thanks
