I've been running the Spectro since my 1st oil change. I change it at 10,000 mile intervals. With 30,000 miles on the bike, The tranny shifts as smoothly and quietly (come-on, it's a Harley!!) as it did when I switched to the Spectro.
Whenever I change it, I have never found so much as a whisker of fuzz on the mag. plug, and it has been as clear and pink as it was when I poured it in.
One of my riding pards, with roughly the same mileage, has had the same results running Redline.
IMO, There is no way you can go wrong with either the Redline SPH or the Spectro Platnium Plus.
I HAVE USED only REDLINE SHOCKPROOF HEAVY in my bikes................. (several street HD's) put many hard miles on them....
I HAVE NEVER FOUND AS MUCH AS A WHISKER OF METAL NEVER---EVER on magnet plugs...
I put a 6 speed into my dyna 2000 FXSD way long ago... Put more than 60,000 miles on it using RED....never ever had metal on the magnet plug.... never had any shifting problems like I heard others having using the same CC gears conversion set that I installed... ???? maybe the REDLINE???
I would think so....
I talk with DAVE the tec/engineer at redline.... He asked me how often I changed the tranny fluid???
I replied max 6000 miles....
he said knowing ME for several years as I was ordering 6 - 8 quarts at a time ,,,UN-OFFICIAL "if it were ME, I would go the once a year regardless of miles..
asking me what it looked like when i took it out? then saying if no dirt or mosture contamanation it could go 2 years before IT need to be change.....
BUT OFFICALLY SAYING:::: follow what your manufacturer reccomends...
I did notice in my 2009 FLHR it reccomends tranny at 20,000 miles....
I use 20/50 redline engine oil
MTL in chaincase
Shockproof Heavy in tranny
I have had such GREAT RESULTS from the REDLINE products I doubt if I would try any others....
even tho' ,,I do like the spectro reports BUT....
