    When I changed my oil, I used to put SYN3 in all of the holes in my 19 FLHXS. I recently did an oil change and I buddy recommended to use the heavy oil. In the short ride, I've noticed a huge difference in how the transmission and primary runs.

    Can someone tell me if these contain the identical synthetic gear oil? They have the same part number; however, they don't read the same. I used the container on the left but when I purchased it again the one on the right is what I got. Harley says they're the same.

    I only have a couple hundred miles on this lube since doing my 10K mileage service. Finding neutral is much easier warm or cold, no fumbling around with the shift lever, glad I changed it.

    Internet shows $21.95 each, at dealer only, then why did I get charged $23.99 each at Phantom H.D. in Manteno Illinois, bought 4 jugs, do they owe me a refund? the lube does give better shifts, lowers 5th gear whine, but did I get stuck for $2.00 extra oer quart?
