RE: Synthetic oil destroy's engines?
Didn't read the entire thread; so sorry if I jumped on someone elses prose.
However, if an oil is so slippery that not enough friction exists to cause the roller bearing to roll, then how in the hell is it going to wear a flat spot?

This way in the spring, my bike is in good shape from all that skating and ready to ride like a flusy[sm=drooldude.gif]

Good grief, this thing is still alive!

FWIW, HD never "condemned" synthetic oil. They also never said it would void a warranty. They have lawyers and they tend to listen to them really well 'cause there are plenty of ju-ju-brains that'd sue 'em if they could find an opening to wriggle thru.
What HD did say was that they couldn't recommend synthetic oil as they had not tested it in the bikes. That's it. Period.
Plent of idiot dealer/dealer sales-pukes/dealer mechs/other mechs/completely uninformed fools said HD said synthetic would void a warranty. If it wasn't an out-and-out lie, it was because they didn't have the command of the English written word a gerbil has at 3 days old and misunderstood what HD said.
To the old geezers who talk about bearing skate - none of 'em are lubrication engineers, and none of 'em have ever offered a shred of scientific proof to back up their claims. Notice the emphasis on "scientific" proof. What Mabel said Joe said his mechanic said he saw with his own eyes means less than zero. Except maybe the mech oughtta find a new line of work where common sense, logic, and the ability to learn new things isn't a necessity.
Anyway, this piece surely is funny. But then it ain't nice to make fun of those less fortunate.
Put it to bed!

RE: Synthetic oil destroy's engines?
At the risk of being the straw that breaks the proverbial camel's back;
I thought I'd throw in on the whole 'bearing skate' issue.I am an OEM field technician/project engineer, and I work on industrial gas turbine engines, reduction gearboxes, output drives, radial compressors, yada yada...I can tell you without reservation that if ball/roller bearings don't skate with Mobil SHC-824 (SHC = Synthetic Hydro Carbon) at speeds of 10,500 to 22,123 RPM, then you shouldn't lose any sleep overH-D engines bee-bopping around atreciprocating enginespeeds.
I would also like to add that I've read Skip's numerous and excellent posts on lube-oil, and he's got his hands wrapped all around the correct information.Read & heed... He knows what he's talking about.
The issue of leaks with synthetics is not due to cleaningout old sludge. Thecause is the molecular structure of the oil and it's 'wicking' nature. I've converted turbine packages from organic (petroleum, ester) based oils to full synthetics, and they do leak more.(If there's sludge in a turbine engine,it's been on fire.)

I also work with anti backlash reduction gear boxes in a highly technical environment. I can tell you and better yet show you with unwavering certainty, that the leaks experienced in those gear boxes can and have been solved by using 100% synthetic lubrication.
Further, your grouping of petroleum and ester based oils as "organic" is errored.
Please share with us your experience of synthetic oils causing leaks due to this "wicking" nature.
I'm afraid I've got to call you out on this one. It's this kind of mis-information that causes threads like this to begin with.

With all due respect for your obviously well rounded experience base... Please explain the synthetics molecular structure and "wicking" nature.

Holy smokes! Not even a week on this list and I'm already called out. Lawdy... Maybe one day I'll learn to lurk a bit more and post a bit less!
Seriously, I'll begin my response with this - I'm a huge fan of synthetic oils for both automotive and industrial applications. Further, having had 1st hand experience with Amsoil in the off-road racing circuit, and I personally swear by the stuff... I'd put it on my sandwich if I could eat it.
My vehicles all use synthetics or synthetic blends, so I have absolutely no axe to grind on the issue of petroleum vrs synthetics. The 'new' 99 Heritage will get synthetic lube and gear oil. My 04 T-bird gets the Motorcraft 5W-20 blend per the manufacturer's recommendation until the warranty is expired, then it'll get a full synthetic. It would have it now except for the fact that Ford has fallen on hard times and is looking for any way to cut costs, and I'm not taking any chances with a pseudo oil-based failure. My wife's Focus gets synthetics as well. I'd put it in my lawnmower, only it's electric and oil seems to screw up the motor windings. (Ok, ok... it was a bad joke)
Now for the issue of leaking. I wish I had something scientific for you, but I don't. I've heard all the stories about synthetics wrecking engines, screwing up seals etc., and I'm not trying to imply anything of the sort.I'll give you a brief(ish) run down of my own experience as it relates to the industrial turbomachinery world.
Based on your post, I have nodoubtyou understand how things are done in the industrialbusiness when it comes to consumables like lubricants. Our company publishes an engineering specification for air/oil/water for our turbomachinery, and the selection of vendor and brand/type is left to the client.We only stipulate the grade, based
