Didn't MCN do all this last year in their 3 part series on oil? Or did they not test shear stability and viscosity retention? Josh | ||

This document (possibly AmsOil propaganda) makes some statements about ElastoHydroDynamic Lubrication (I won't even pretend to have previously heard of such a phenomenon). Just scroll down to the picture of the booger colored roller. One of the things they describe is that a fluid under pressure effectively increases its viscosity. The page leads me to believe that a synth oil possibly has LESS of an increase in viscosity than a pure dino oil. Does anyone else get the same interpretation? Maybe the rollers don't like the lesser viscosity / pressure coefficient of synth, though I doubt it would be to the extent of it being BAD for the bearing. I must emphasise that MUCH more so than usual, I REALLY have no idea what I've typed above. Just trying to make sense from dysinformation. -Saro | ||

I don't think MCN tested HD360, did they? | ||
| José_Quiñones |
I think they did, I'll have to look it up and scan it. That's an odd statement for Mr. B to make. I know for a fact that Tilley uses Mobil 1 in their race bikes, at least the last time I saw them at VIR last year. Synthetic/dino is not the issue really, it's the additives in the oil that hold the key. | ||

American Iron also had a great series about oil including a nice article by Chuck Goldman of Mobil. More scanning....... | ||

Must have been during '00 as I don't see the 3 articles listed in the Dec 01 issue index. If José doesn't post summarys I'll try to next week. | ||

The Mcn article was very thorough, they did test the Harley oil. Unfortunately I don't have a copy of it(it was borrowed). I do remember the Harley oil did well among conventional oils, but synthetics were in a class of their own surpassing conventional oils in every catagory by a wide margin. It would be great to have that article archived here. Rob | ||

Jmartz, The purple Redline oil you did use in your tranny and turned into green goop: Was it Shockproof Heavy, Shockproof Lite, MTL, or 75W90 ?? I want to make further inquiries now, before I pour the oil of my choice into the tranny. Thanks. | ||

I haven't had time to scan anything, but I have this thought: If HD360 is so special and specifically tailored for air cooled, roller bearing engines (i.e. Buell/XL/EVO/TC88), how come it's the same oil HD recommends to use on the new liquid cooled, PLAIN BEARING VROD engine?????? | ||
| José_Quiñones |
oil is oil, as long as the additive packages are similar, there is no reason not to use a synthetic blend. | ||

This webpage is an Amsoil one, but it has the first three of the very good OIL series in AMERICAN IRON MAGAZINE, from 2000. Follow the link here This saved me a LOT of scanning! | ||

UGH José that was more information than I ever wanted to know about oil...Makes me hate the MC a bit more. I wonder why they (HD) persist in not publishing the properties of the "Sportster Transmission Fluid" I'm also hoping that the Firebolt will push folks into coming up with a replacement for the OEM oil filter (it also works on my Blast) Yes I read it all and then some more on both the AMSOIL page and Donnie Petersen's webpage Good stuff. | ||

Maybe a topic hundred times talked about, but... My magic engine has been serviced at a HD shop. I guess they put HD mineral oil in the engine. Something is wrong, because it takes less than 400 kms say, 250 miles, for the oil level to rush between the two marks on "the burn your fingers" dip thingy. I fill with more and more synthetic oil. But the engine is not really working that bad. I use it in European background (fast, load, all that kind of bad things we do over there). The breadbox is not filled with oil, puke or magic fluid. A bit greasy, a bit damp, but not soaked. I consider three things : Oil will leak from under the engine because of the overfilled transmission (damn HD mechanics..). But from 1 liter to 28 oz it dosn't soak arm, wheel and muffler for 2000 kilometers. So I guess that somehow it's the same oil that is escaping from the tank and leaking from the transmission hose. A crankshaft seal or so. But doesn't the trans fluid should be as black as engine oil in that case? Or the other way : bore is dead, blowby is worse ever recorded. Trans is leaking. Warranty. Or bad, bad mineral oil dosn't like to be put under the constant strain of a hooligan riding as much as he can around 100 mph, or full load, and protest by evaporating A LOT With this statements, I can expect : -Light coming from the BBS and the solution is here ! -Consider buying a shotgun and trying to find a good mechanic and have him working on my still under waranty M2. Rather put synthetic oil than using a cooler. Rather put a cooler than slowing down. Rather finding a way that doesn't need two catch cans, a cooler, oil gauge, ten hours of dyno jetting and two priests to work. Thanks to anyone who can help. Thanks to anyone who cared reading. A bientôt ! PS : I'm supposed to have learnt engineering in remanufacturing car engines, but I started Buell, high-perf pushrod engine and Imperial, standard, or whatever you wannacallit screws. SO far I consider I know nothing about HD engine, so specific compared to the usual truck engine. PS² : Tried to help airflow, gutted airbox. suffered instant cuts by the termo sensor at top speed. maybe a bit too hot ? | ||

Good Boy, Sounds very much like you could have a leaking crankshaft seal. Check your transmission level. If it appears overfilled that is a good indicator of a leaking seal. Just one note concerning engine oil level... it must be checked soon after shutoff of the warm engine as some oil apparently does drain back down into the crancase. It is wise to not top the oil ALL the way up. As long as you have oil between the two marks on the dip stick, there is no need to top it up. Bon soir, Blake | ||
| Good_Boy |
Thanks Blake... Trans level appears to be just over the bottom of the diaphragm spring. Say, 5mm, 2/10 of an inch ?. Hard to check too, you need to go to the store to buy a spare #27 Torx head because the previous one broke apart, just because it has seen the screws... Trans leak since serviced, from hose and cover plate. Cover plate leak appears to be reducing somehow... It's gonna take forever to change that crankshaft seal I'm afraid... And I'm going to change oil as soon as possible, use synthetic and put that Audi oil filter, for bigger capacity (topic has been discussed forever, can't harm and increases thermic inertia...) Mtewie has only 7000 kms on the clock... a bit early for that. Thanks a lot, I'll try to ged some texan ypee fashion to say merci beaucoup @ work. And I'll buy the shotgun... | ||

After reading all the Oil links provided here. I commited myself to running Mobil-1 15-50. Wal-Mart had it for ~17 per 5 quart container. I sucked up and bought the filter from HD. Changed over yesterday afternoon. Seem like the lifters quite-ed down a bit. We'll see what oil consumption is like after the trip to Weir's this weekend. If it weren't for a new front tire, I'd have run it today, even with the rain forecasted. I hate to stir up a oil controversy, but I have a question. What do you think about Mobils claim about bike oil for bikes , and Car oil for cars statement on the FAQ? Thanks, Andrew | ||
| Blake |
I don't know. They won't give any specifics. At least Amsoil basically admitted that due to market pressure they basically repackage their automobile oil in a motorcyle bottle. Kudos to Amsoil. | ||

I believe it was Motorcycle Consumers News that has a report some news back that dispelled the whole motorcycle oil myth. Russ | ||
| Blake |
Yeah, but now we have an "SL" rating on the 15W50, so until I hear that like with the "SJ" rating, 50 weight oils are not affected, I've switched to the V-Twin 20W50. Plus I want to support my dealer who is now stocking the Mobil-1. | ||
| Andrew |
Well, I am not going to worry about it. The bike feels smoother, runs a bit quieter. Seemed to be a little cooler too. Though I'll have to wait some on that one. Has anyone fabricated a hi-capacity oil tank fot their S3? How much oil capacity did you gain? Have you had any issues with breakage or interference with swingarm/tire? | ||

Andrew: This is a QUICK fix for increaeing system volume!! Go to a FORD Motorcraft FL-1A and your system volume will go from 2 1/2 qts to 3 qts. I paint my FL-1A's flat black.... Erick Buell gave all us bullers a hint with the FIREBOLT by putting a OIL COOLER on it from the factory(ie: if you make HP you make heat).. I'm running a sporster oil coller with a big twin thermostat..... In buelling BUELLISTIC and/or Hardley-Harley | ||

Andrew, Check out  these 3 qt tanks | ||
