Hello all,
First post for me so here it goes. Just picked up a 2005 FLHTCUI a year ago and have been using syn oil. Now today I decided to change the oil and thought about the oil cooler I have attached and thought to myself, do I still need to run syn oil with a cooler if I am not doing any heavy traffic stop and go type driving? Cooler only works if air is blowing on it anyways, but if I do nothing but cruising at highway speeds and the engine isn't ideling for long periods do I need to waist the money on syn oil? Isn't the cooler keeping it cool at highway speed?
Thanks,
Electra1
