I really hate asking an oil question, but since I'm fairly new to Harley's, I'd like to get opinions from those who have a lot more experience/knowledge than I do with the Harley brand. I dont want to start a whats the best oil thread, just asking about a particular brands weight & viscosity for the FXDC. I purchased a 09 Super Glide Custom late last year with 6600 miles on the OD (my first Harley and I love this damn thing). I know what the manual says to run, but I have another air cooled 90 degree V twin (2016 Moto Guzzi Griso 1200) that I run here in Florida where it is hot most of the year.
Because of the heat here, I run full synthetic Motul 7100 4T 10W-60 in the Griso and its performed well in that bike over the last four years. Doing some online research, several of the oil manufacturers recommend this weight as one of three options for the FXDC, with the other two being 10W-40 & 20W-50, including Motul's website. I'd like to know if anyone else runs a 10w-60 in their Dyna, is there a reason not to run it in my FXDC?
Thanks,
Rick

I run 20/50 synthetic. I live in Las Vegas, and it gets very hot here. I ran 20/50 synthetic in my 2009 Ultra Classic for 90k miles before I sold it 2 years ago, no issues
OK, it's still an oil thread. What is in it now? 20x50 dino or synthetic will do just fine where you are. Valvoline is good stuff, but whatever you use is up to you. I wouldn't run less than 20x50 but that's just me.

Way, way off topic; but because you're a bass player i thought you might enjoy this YouTube clip. Found it by accident the other day:

The 10W60 isn't going to hurt anything but we typically recommend the 20W50 in most cases, especially in a warmer climate like Florida, as it will give a bit more protection when first firing the bike up and setting off.
We recently developed an entire line of lubricants just for twin applications with a 20W50 engine oil, a gear oil, and primary oil. Worth trying out and we've received good feedback from riders who helped develop it and a few members here on the forum:
