I live in Central Florida and ride a 2011 Triglide. I changed my oil, at the start of the summer, to the Indian 15w60 full synthetic oil. I also went with Harley Davidson Heavy Synthetic Gear Oil (80w140) in the transmission and primary. My experience so far has been totally positive. My engine is running quieter and maintains a little better oil pressure when it is hot. My transmission is shifting quieter with this gear oil, I was using Syn3 before. We have had an extremely hot summer and I feel this might be better protection for my tri. Has anyone else used this combination? If so what was your experience.
