Mobil Super 5000 10W-40

Any idea if this oil would be a problem with a wet clutch bike, with its Ti friction modifier and all? I'm going to change my oil tonight with this oil and I'll find out. Get a used oil analysis as well, but that won't be until Octoberish.

I don't see any used oil analysis that use plain auto conventional oil, just rotella variants and synthetic auto/moto oils. I hope this eventual used oil analysis will be edumacating.

what steers me away from virtually any PCMO and the majority of HDEO's (exception are the Rotella's with JASO MA rating) is the addition of moly and other additives that are filling the gap left by reduced ZDDP...it's hard to tell the amount of moly that is 'safe' for wet clutch bikes;

if it's of any consequence, one of the shops I frequent uses Castrol GTX PCMO in any oil change where the owner doesn't ask for a specific product and the owners (folks I trust alot) state they have not noticed any problems or had complaints about clutch slippage

if I didn't already have a case of Suzuki V-Twin synthetic blend motorcycle oil, I would definitely be hopping on this --->

SUZUKI
4-Cycle Synthetic Racing Oil (awesome price, even with shipping)

Some folks have no problem running PCMO's in their bikes but why risk it? Rotella and Delo are readily available for a reasonable price.
What bike are we talking about?

I prefer the more robust diesel engine oils and motorcycle specific oils than any passenger car motor oil. I agree with bigdreama.

About moly...Shell Rotella T6 5W-40 contains some moly according to the virgin oil analysis page. Schaeffer #707 v-twin motorcycle 20W-50 data sheet tells of their two friction modifiers, Micron Moly and Penetro, and it passes JASO-MA2. I've used the Rotella T6 with good results in my wet clutch, and if I used a 20W-50, Schaeffer would be my first choice.

Ok, so I chickened out. I went with a different set of logic. I bought Castrol Power RS Racing 4t 10w-40. My thinking was that I'll try the ultimate in motorcycle oil and see if I can feel a difference between it and the Rotella 15w40 that was in my bike. Absolutely zero difference in shift feel. So much for that. From now on I'm gonna go with rotella, seeing as its 13 a gallon compared to 40 a gallon and offers uoa proven protection and equivalent shift feel as the most expensive motorcycle specific motor oil I could find. Maybe, just maybe I'll go with the rotella t6 for better startup protection.

Oh btw the bike is a 2004 Honda 599 with 7200 miles on it. I bought it with 4500 miles. Great little bike, handles like it's on "a rail".

I tried the Castrol RS V twin 20w50 and hated it in my Triumph. Found the Valvoline 4t Syn to shift much better from the start and stay better. Felt like the Castrol sheared much more easily as the shift quality went to hades in 1k miles.

a good left foot can tell as much about an oil in a shared sump bike as a lot of very expensive equipment can.....to a seasoned rider.

I came upon this thread after doing a VOA search on this Mobil Super 5000 oil. I want to confirm if their 10W-40 weight comes with the titanium like the lighter grade offerings. It says on the Mobil PDS that only 5W-20, 5w30, and 10w30 has friction-reducing additives. I'm wondering what the 10W-40 comes with.
