5w40 HDEO vs 20w50

[1WildPig]

I used the 5w40 Mobil 1 synthetic Turbo Truck diesel oil in my previous 2013 Harley Ultra Limited this past year and it worked fine... I've got a 2017 Ultra Limited now that will probably get some after the warranty is out...

Think Delvac 1 is still $22/gal on Walmart.com … buy two and get free shipping …

Has anyone run a 5w40 synthetic HDEO in their Harley during the summer on a regular basis? My gut says it will be fine but just want to make sure.
