RE: Mobil 1 Fluids
Since you asked about Mobil oils, I like Ultra Jockeys suggestion because using MX4T in the primary will work just fine and at a lesser cost that using V-twin. Of course, it adds another type of oil to stock in the garage. I have one of the dealers preferred packages and so I supply my own tranny and crankcase oil but let them install the formula+ (at their cost, per se').
This last oil change I did switch to the 75W140 synthetic for the transmission since AZ gets quite warm in the summer. I think on the next change I'll just go back to the 75W90 and stick with that. Also, I do replace all the oils at 5K.

RE: Mobil 1 Fluids
I read an article saying not to use Mobils V-Twin in the Primary because of the friction modifiers they put in it. Some say it causes the clutch to slip excessively. Got a buddy that has been riding HDs longer than I have been alive and he said to always use tranny fluid in the primary because tranny fluid is specifically made for the clutches and the chain just needs any oil to keep it lubed. I use V-Twin 20-50 in the crankcase, Mobil full synthetic 75-90 in the tranny and Mobil 1 synthetic tranny fluid in the primary. No wonder ExxonMobil is making so much GD money!

RE: Mobil 1 Fluids
I too have been on the "perfect oil" quest and spent hundredsand hundredsof dollars in the last25 years and came back to Mobil 1. This is not my first TCand I have hadmany HDmotorcycles (and other brands)over the years. I just feel with the experience I have had that the perfect combination for a new HD is...
Mobil 1 V-Twin20/50 in the crank and primary and Mobil 1 75/140 in the transmission.
I am by no means an expert, nor do I sell the stuff...I just know what works.
