  Hello All,

  I ran a search for oil and oil change, didn't find anything specific regarding 1 oil 3 holes  

  Has anyone taken this option up? Only area of concern would be the trans. 20/50 a bit light to be in there? Running full synthetic. Penrite or Mobil 1 whatever I find cheaper of the two.

  In an earlier life i worked on earth-moving and track machinery, the quest for an oil that did everything was the ultimate goal.
  

  
  

  There is no ultimate oil that will do everything, it does not exist, that is why there are still a myriad of oils today.
  

  
  

  Each oil has properties specific to its application, a lot of guys think oil as something that comes out of the ground or lab then put in a container and sold, not the case, oil is only a carrier, additive packs make an oil specific to its task, hence making it unique to its task.

  
  

  Back in the day when doing field service on a number of different machines, we had a fair few repair trucks with around eight different 200L drums of oil, if we could have got that down to just four or six would have been a considerable saving is space, cost and weight, not to be, the closest to a universal oil was 'Castrol Agricastrol' ,this, even then was only applicable to Massey Ferguson 50 backhoes, that was it.

  
  

  Get the oil recommended for the task at hand, oil's cheap. unless cost is the overriding factor of your machine.
  

  
  

  Cheers.

  2007 Dyna Super glide custom. Did find an interesting (but long) video on an oil discussion on YouTube. Have a look at Kevin Baxter oil talk. I am leaning towards 3 different oils, it just not that hard or expensive, but being a wee bit lazy I thought 1 oil, all holes it'll do...

  I use three different oils
  

  Motul Twin Syn in the engine

  Spectro gear oil in the tranny

  Spectro primary oil in the primary

  
  

  I can’t see how 1 oil could do anywhere near as good of a job than 3 specialist oils.

  Just run Harley oil and run what the frigging manual recommends.  There are millions of Harley riders using oil and EVERY one of them has a different opinion on what to do.

  I put Penrite 10W 50 full synthetic in the three holes. Have been doing it for about 5 years without any problems. ( Probably about 25k  kms)

  When I first did it I was concerned the gearbox might be a bit clunky but I couldnt notice any difference.

  Ha ha, oil threads always cause a stir. It's not so much the type, more the application. Amsoil and a few others say 1 oil 3 holes. Just wondering what people have found 

  Regarding Harley oil, have a look at the mentioned oil chat by Kevin Baxter.  It's got a few good points, mind you it goes on a bit

  For those that don’t know, this fella possibly knows more about engines and harley stuff than anybody else, at least in Australia. Take what he says as very credible information. For those new to the forum have a look at his past posts and learn. I may sound like a brown nose but I’ve got nothing to gain and only pointing people in the direction of where helpful/credible info originates.

  The Screaming Eagle Syn3 and Mobil1 both say it is fit for 3 holes.

  Making sure you change it regularly is a biggie too, lots of blokes change oil more often than the regular service manual intervals.

  I like redline in the gearbox. Makes the box shift really smooth

  Same as you Hoody, done a bit of work on earth moving gear. I was on a job up at Argyle Diamond mine and we had to service a D 10 dozer but we ran out of transmission oil . I think it was supposed to be 30 weight from memory.

  It was a big service and the hydraulic oil had to be changed as well but we didnt have any of that either so we filled the tranny and hydraulic tank with engine oil. 20 W 40  i think. The operator reckoned the gearbox was shifting better than it had ever done .

  While that dozer was in the workshop we had to change a track roller.  

  That was about as funny as a kick in the fukin  nuts.

  More than half the motorcycles in the world only use the one oil, a lot of them don’t have seperate crankcase, gearbox, primary drive reservoirs.

  That is true, but there are a lot of variables ( types of bearings, different metals and so on ).

  even with Harleys, you can't just use , the same oil combinations in all the models. 

  but if your not doing a lot of riding, or don't keep your bikes long. It is not important.

  if you ride a lot and plan on keeping your bike forever. It is important!!

  Anyway.... the ONE thing w all seem to agree on is that Redline in the Tranny is the bees knees.  Shockproof in bikes with a separate tranny oil supply and then normal in Sporties.

  Well said Krash.

  If you want to keep yout bike for a few years you gotta treat it right.

  Engines and transmissions have different specific requirements for oils. They have very different jobs to do and are exposed to very different environments or challenges.

  Choosing correct oils is one of the most economical maintenance choices you can make.
