I've been running Amsoil synthetic oil in my pick-up for the last couple of years. Motor runs quieter , smoother , and I picked up about 1.5 miles per gallon , I change it out every 10,00 miles.
Anyway....I plan on switching over to Amsoil on the next oil change of my FatBoy. I've read in other forums that the synthetics help both the Evo's and the TC88's run cooler , and quieter.....have any of you Guy's , or Gal's switched over to synthetics in your scooter? If so , what results have you had ???

 

Been running RedLine for over 15K, No problems at all.. Couple of my buddies are now running RedLine, and are really impressed with the difference..... Cooler, Shifts easier, etc...

 

Best move I made was to switch to synthetics. I have a '96 Ultra/Standard and a '94 Ultra. As far as brand goes your going to get recommendations on all brands. I run Mobil 1.
