Will it hurt anything if I change from Syn3 to amsoil. I like the reviews I have heard about Amsoil. Thanks for the replies
No problem swapping from one to any other motor oil. Amsoil is fine, as is Mobil 1 and a host of other fine synthetic products. Take your pick based on availability and price. As for Mobile 1, the 15w50 is also fine for your HD and is about 2/3 the price of the V-Twin 20w50 variant.

I run Amsoil and to tell the truth I had thought about changing back to Mobil1 cause I thought that my oil got a little discolored quicker, at least thats what I thought, but when I changed my oil at 5600 miles it was still slick as can be, no grit and actually pretty clean after I drained it out, I also cut open my filter and there was not one piece of cam tensioners in the filter and my bike has 16,700 miles on it, we did the same to a freinds bike at 15,000 miles and his filter was full of tiny pieces of orange tensioners, he used Mobil1, now Im not blaming Mobil1 at all, but I really like the way my oil pressure does on Amsoil when it gets hot, it seems to rise a little, almost like it thickens just a tad, maybe to a actual 50wt like it suppose to, anyway either one you choose will be fine, my choice would be 1st-Amsoil 2nd- Mobil1, no other choices.

Has anyone ever really had engine problems due to Syn3, or dino oil for that matter? Run what you want but they have all worked fine for me.

I'll be changing from thedealer-installed Amsoil to Mobil 1 when I do my 5k service. Never saw any reduction in engine temps and the tranny noises (whine in 5th & "rocks ina can" in 6th) got worse with Amsoil. Amsoil might be good oil, but in this case I believe I'll be better off with Mobil 1 or OEM.
So what your saying is that you put Amsoil Severe Gear 80-140 oil in the tranny and the Whine got louder? Or you put in Amsoil 20-50 and the whine got louder, as it should with a 20-50 weight oil. Just asking because your the first one i've heardwho said the whine got worse if you added the Amsoil SG 80-140.

Dealer put Amsoil Severe Gear (don't know the exact viscosity) in the transmission and the whine in 5th got louder, and the 6th gear "rocks in a can" sound, that wasn't there with H-D's factory oil, suddenly appeared.

OK I just put Amsoil in the Crank 20/50 and Trans SVG 20/140 and so far I haven't had any real changes from the Syn3 except I did notice that "the little bit of whine in 5th I had" does seem to have gone away.
I went with Amsoil because I counldn't find Mobil 1 V-twin anywhere without mail ordering and it would have been more $. Not at Autozone which BTW I live in Memphis where there HQ is, Walmart or any other place I looked except for a Victory who wanted $10 a quart and I paid less for Ams.

So Amsoil dudes when do I get the secert handshake and how long before the manna falls from the heavens, dancing girls, come on give me something here but keep the Koolaide
I even joined the Prefered customer thing and I got a folder full of stuff but you think they could have at least throwed in a sticker but nooo....
