Welcome Trex0864 to the HDT forum. When reading your post I noticed you said 20/50 Mobil One for the Harley and not 20/50 Mobil One V-Twin...so we need a little clarification regarding your selection. There IS a difference between automotive oils and motorcycle oils...:s
Unless I'm mistaken, Mobil 1 V-Twin is the only 20w50 Mobil 1 makes.
The closest automotive M1 is 15w50 which some of us will use as well.
Oh yeah, and I use the M1 V-twin as well.
