I was not judging the quality of the product...just the price..I thought this must be some good stuff...or is this is just another dealer giving it to the consumer!
All shops in Central fl no longer carry it. I also was disappointed with the performance of the Spectro Heavy Duty Primary lube in my sportster. With exact same miles on the spectro as the prior changes it has 2 to 3x the amount of stuff on the magnetic plug. I will not purchase it again.
No idea how their synthetic gear lubes perform. I did put the 75 140 spectro in my neighbors 07 night train so I will comment on that when I change it again. He did comment that thus far shifting and sound are favorable over the 20/50.
spectro Gl-1 is the best stuff i have used , really made a difference over the fresh harley tranny oil I put in , will never change to anything else , as glider has mentioned u need the GL-5 in the 6 speed the rest use the GL-1 , real smooth shifting
