Posted below since @HEMIMANN was talking MC's. Nothing more familiar than the Clunk of a HD V twin going into gear or the slap of an M-16 type weapon chambering a round, both highly recognizable sounds, LOL.Well, it is the Synthetic Oil Thread, and lubrication is lubrication, so......
I bought new 2021 Softail Heritage Classic with M8 107 engine. Mine never did just clank at startup - it clanked all the time! So did gear shifts.
I'd suggest Mobil 1 V Twin + Lubegard will be close to Red Line. Since we're supposed to change engine oil annually regardless of mileage (I don't approach maximum 5k mileage for OCI), I'd say choosing either would be a good choice.
As important is changing the transmission and chain case lube. Definitely go Red Line there, since these are drive boxes that don't get contaminated by combustion blowby, therefore the OCI's are much longer. And they don't take nearly the amount of oil the engine does. There are two different oils for these boxes - RL Chaincase Oil and RL Shockproof Gear Oil. You'll be amazed how these lubes quiet down the clanking. Which means they lubricate much better.
OK, the below is all IMHO and my experience. I am by no means a mechanic, but I can turn a wrench for things like plugs, oil, etc etc. DO as you may see fit and use whatever product you like, but read all those writeups on commercials with a grain of salt, LOL.
BE real Careful what Oil and Additives you put in the Tranny on a HD. Remember, it is a wet clutch tranny, and you could cause problems with your clutches if you put in the wrong oil, or maybe a restricter additive eat up the clutches, just saying.
What always amazed me, the HD shop always just threw in the same oil in the trans and the engine, the same HD slush. I always for years have used Mobil 1 Full Synthetic for both. On my Honda, the Trans is totally integrated, and not separate with Trans so U best know what U are putting in there that is 100% compatible for both the trans and the engine.
I ran Mobil 1 for my V Twin and Used either Redline V Twin or Am soil V Twin Tranny Oil, whatever I could find. Pic below oil ref left side Honda Motor right Side HD Engine. Before the haters get on here, THIS is what I run on my Honda Gold Wing and What I used to run when I had my 08 HD Ultra Classic with 96 Motor. Not only do I have to go high end for the motor but also heat, because it can get over 100 degrees and stay there here. And nothing hotter than Air blowing off an air cooled motor at 100 degrees or off of my block 6 cylinder Honda Motor.
Left side what goes in my Honda and right side what went in HD.
On the right (white) is my old 08 HD Ultra Classic, which I traded up/down for my 06 Honda Wing.
