So im using Amsoil 15W-50 metric motorcycle full synthetic on a 2011 Triumph Bonnieville T100 865 cc air cooled efi bike.Triumph calls for Castrol power 1 15w50 full synthetic. Always used Amsoil on all my bikes and trucks with no problem but have been told by a few mechanics that using the Amsoil metric motorcycle oil on a Triumph would make the bike s valves sound louder more of a ticking noise almost every bike I owned all make this sound and its totally normal u can tell when a adjustment is needed when its real loud.My question why would Amsoil make a bikes valves sound louder its my first Triumph motorcycle after riding Harleys and Indians for many years witch are no quiet bikes by any means So far my triumph is not any louder but im just curious if anyone experianced this or heard of this with Amsoil on a Triumph

So you haven’t actually had this issue but you’re just repeating some unverifiable and completely random rumor to see who else will join in?

Amsoil is good oil. It’s not even really more expensive in the motorcycle flavors. Run it. It’s fine.
Triumphs need all the help they can get. Ask me how I know…

Maybe it’s a on the thinner side of the 50, and the other oils a bit on the heavier side?
I love Amsoil any of my older quads and bikes and the newer ones run great on it
My answer - it won’t.
Lots of people “hear” things when they change oils. But they’ve made no objective, controlled measurement of the noise before the change, and of course, none after.
It’s purely perception with a multitude of explanations that have nothing to do with the oil.
These rumors get repeated, and other people “hear” the same thing.
Don’t buy into the rumors.
Agreed. Never could hear a difference. Never felt any seat of the pants difference, either. Heck, I never even noticed any different ju-ju between oil brands.
I usually say to myself its prob me just thinking its louder or i never really stopped to liaten Im sticking with Amsoil I have used and trusted it for years Thanks for reply
No im asking a question so far its good and it was just a question isnt that what forums like these are for to ask questions
Castrol Edge vs Castrol Magnatec - I can assure you that Edge is "noisier" in a couple of our cars that I've used it in. Others here say the same thing. Did any of us whip out a dB meter and measure it ? No.... In my case, it's not a situation where I don't like Edge and I tried to find reasons to justify it but I've switched back and forth a few times and am absolutely convinced it's noisier. Is it because it's 0W-40 (Edge) vs 5W-30 (Magnatec) ? In the summer, I doubt it....
Riders can be easily fooled when it comes to engine noises...
Amsoil metric is one of the better oil for motorcycle in the market. I am using Amsoil metric 15W50 on my 23 R1250GSA now. I did not notice any difference in noise from previous Motul 7100 10W50 I was using. You can try Motul 7100 15W50 to see if there is any difference.
I easily heard the difference using Mobil 1 15/50 oil compared to an oil I used for almost a decade now JT8 HEDO 15/50 semi syn.
The Mobil 1 I could hear more noise for sure. I thought it was a well known fact with most full syn oils compared to conventional.
Conventional oil has uneven particle sizes, nasty wax and other stuff compared to Syn.
I thought it was known this makes them more quiet.
Anyway it doesn't mean the synthetic causes more wear. It doesn't, in fact it's less wear and cooler running engine internals. But the noise makes some think it is inferior.
I posted right in this section of the forum Blackstone wear tests which had 3 or 4 wear tests of my favorite 15/50 JT8 semi syn compared to one run of Mobil 1 15/50
Even though I went back to the JT8 the Mobil 1 Blackstone wear tests showed superior as far as metal in the oil. I think but was unable to reliability document that the oil ran MAYBE 5 TO 10 DEGREES cooler.
SO why did I go back? The JT8 still had very good numbers and figured in the life of the engine it would not matter. I have used this oil since almost the bike was brand new since 2014 (2014 Harley Road King) and the bike has never needed a repair to this day for anything.
Even though the Mobil 1 had great numbers the noise bothered me a little. Also the JT8 met Harleys recommendation for an HDEO if Harley oil was not available. The Mobil 1 doesn't even though it carries an obsolete HDEO rating.
BTW- I have a brand new jug of Mobil 1 15/50 in my garage for the next Harley oil change. I am revisiting trying it like I did a couple years back. Nothing to lose, get wear numbers.
and easy to buy.

Amsoil is good oil, but this 15w-50 Metric immediately caused my clutch to slip on a 2023 KTM 890 Duke R with only 5,000 miles. I went home and swapped oil and filter back to the MOTOREX Synth 10W-50 and the slipping was gone. I assume the Amsoil does actually not meet MA2 specs and is just regular automotive oil. DO NOT use this ina KTM bike!!!
It does meet MA2. It's not just automotive engine oil rebottled. Something else was going on, maybe combination of oils absorbed into the clutch surfaces. Don't know. Did you contact Amsoil or your Amsoil dealer? I sold lots of MFF 15w-50 to plenty of KTM owners and no issues. Do you still have the oil?
How do you know that?? I've known you for years Pablo since I have been member here since 1997 under a different name (Alex D) so I respect you, BUT There is NOTHING else going on except a simple oil/filter change. Period. I used the Motorex Power Synth 10W-50 before and this time switched to Amsoil Metric 15W-50. Clutch slipped under full power immediately after the change. Went home and drained the Amsoil and replaced it with Motorex and a new filter. Slipping was gone. This oil does NOT properly function to specs in my KTM 890R. The bike is pristine and I owned it from new.
Know what? That Amsoil doesn't just re-bottle car engine oil? Because they test the heck out of the MC oils. They have test areas dedicated to MC oil testing.
I'm not at all denying you experienced this, that was not my point at all. I fully believe it happened exactly as you describe.
I am merely trying to get to the bottom of it, the root cause vs just telling everyone the oil doesn't work in a specific MC.

Anyone can print something on a bottle and try to get away with it. I have purchased Amsoil products for going on 20 years and I am a preferred customer, so no Amsoil-hater here!. I would NOT recommend this oil for a motorcycle. MC specs (MA and MA2) deal with the friction coefficient of the oil. MA/MA2 oils do NOT contain friction modifiers present in automotive oils because of the wet clutch systems. That is the main difference between automotive and MC oils. Many clutch systems may actually accept automotive oils. Anyone can do whatever they want. I do know KTMs can be picky with their oil and clutches .. I had a similar issue with a KTM200 Duke years ago that would not accept semi-synthetic Valvoline MC oil for the clutch to work right and I had to go back to conventional MC oil.
