Hi folks!
My older brother is a Harley rider and wanted me to ask a few questions on his behalf. He owns an '03 Electra Glide with an 88 ci motor and a '14 Road King with a 103 ci motor. He's looking at Mobil 1 gear lube, and is wondering which to run in his primary's and differentials. He told me there's two different weights, one is a 75W90 and there's a heavier weight, I think he said 75W140, I'm probably wrong on the second weight, sorry for my ignorance on motorcycles.
Anyway, which gear lube is preferred, and what do the Harley riders think on Mobil 1's 20W50 for the motors in his bikes?
Thank you in advance.
