Not Impressed with Mobil 1 VTwin

I just used it for the first time in mine . The top end
may have been a little noisier but that was offset by
a lot better idle oil pressure . I'm happy with it .

No suh spec as Semi Synthetic.
I am just finishing up my first Mobil 1 oil change (3000 miles) I am not overly impressed with it. I have used HD dino oil (best so far), Syn 3 (was okay), Valvoline Synthetic (not bad), and now Mobil 1 (least favorite so far). It makes the top end very noisy, and the bike appears to run hotter. By the way it's a '15 limited, with 15,000 miles on it.
Going to try something else most likely either Schaffer's, or Spectro. Also thinking it will be a semi-synthetic. Guess I will keep on trying until I fine something I like.

Constantly changing oil brands can be a bad idea; unless you're using some kind of extraction system, you're mixing a quart of the old oil with the new oil every time.
When you switch between brands, you always want to make sure the API ratings are the same. Mixing the N standard with the SJ standard then throwing in some SF can really mess up the oil properties.
Give Mobile 15w50 a try. It is SN rated, which is the newest rating, and it's friction modifiers instantly made my engine run much smoother when I switched from SYN3.
15w50 is car oil; do not put it in the clutch...it contains friction modifiers that quiet the engine, but will mess up the clutch...spoke with a Mobile Tech; the 15w50 is perfectly fine in a Harley engine.
Look at your owners manual, do not stray from what it recommends as far as viscosity/air temps. Running "Heavy" oil in an attempt to "quiet" the engine is a terrible idea. Too thick an oil, and you starve critical parts at start up...keep doing that and you'll have a lot more than just "top end" noise to worry about.
Harley top ends are just noisy; it's that 1950 tractor tech. At idle, low rpm, the noise is normal. If you accelerate through some gears, and really load the engine, then that top end noise should vanish...if not, you've got some top end issues to repair.

Mobil v-twin has much higher levels of anti-wear additive packages than any other oils i researched. using good oil is the cheapest thing you will ever do any engine. to each their own, but you should be using a quality lube.

"AMSOIL synthetic motor oils are compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Mixing other oils with AMSOIL motor oils may also void the AMSOIL limited warranty. "
"To minimize the risk of performance- and warranty-related issues due to improper mixing, AMSOIL does not recommend mixing AMSOIL synthetic lubricants."
Mixing brands of oil, especially if they carry different JASO and SAE ratings (that would be improper mixing), is just a plain old bad idea.
~~~~~~
This will vary between bikes, but the service manual for mine says that at least 1/2qt will be left in the machine.
