Default Changing oil Type

I have a 03 FLHTI, and have using HD Synthetic oil in all three holes from the get go. I have seen in this forum Amsoil seems to be the favorite oil to use, my question is, is it alright to start using a different oil. I know some of you think this is a dumb question, but I have been told not to do this. Never had a problem with the HD oil, and I have a stock engine.

Won't hurt a thing. The only thing to consider is supply. If you don't have a reliable source for your oil, that's a big consideration. I use Mobile1 V-twin, because I can get it at 2 stores a mile away from me.


Waiting for the oil debate to start.....................AGAIN.

As has been said, won't hurt a thing. However, I would add that whether you change or not, start using a gear lube in the tranny and conventional 15W40 or 20W50 in the primary.

Oh Goody!
No oil threads in a while now we have two!

It's alright to switch oils, just not to mix them. Reason being you don't know if they are compatible. They could react badly, they could bond together and form a gel, either way not good, so drain it completely and make the switch.

Amsoil is a great choice but I wouldn't use it in the primary, the simple reason is; your clutch needs friction to work and Amsoil is very slippery and not the best choice in there.

If your having no problems, why change? Doesn't make sense to me!

Yeah, like they say, if it ain't broke don't fix it because you might fix it until it's broke.

K. Your are incorrect. Amsoil is not more slippery than other oils. It's has the JASO spec which means it's wet clutch safe.
Now some synthetics contain molybdenum disulfide. It's a friction modifier and yes it makes oil more slippery however many conventional also contain it.
Now. I would agree you don't need a synthetic,expensive oil in the primary. Some guys use just plain old tranny fluid in it with no ill effects.Rotella 15w-40 carries the JASO spec and it's cost effective.
When are people gonna get it. Just because oil is synthetic doesn't make it more slippery.
Bearing skate ring a bell. A made up condition to push Harleys brand of oil.

And the gear oil idea in the tranny is a good idea. Baker makes a tranny of the same type as Harley does and they do not recommend motor oil in theirs. And all they do is transmissions. I am going to assume they know what they are talking about.
