Let me put on my flame proof suit........

I've used Mobil 1 for my cars for years (full synthetic) and when it came time to do the 600 mile change on my Z400 I went with Mobil 1 Racing 4T 10W40  oil with an OEM filter.   The bike shifted smoother and has never slipped. 

I intend to use this on my Z900 if I ever get to the 600 mile mark (darn weather) or maybe the Kawasaki full synthetic.   

Is Mobil 1 considered crap by the forum?  If so why?

No.
As long as it says JASO MA1 or MA2 on the bottle you are good to go.  :305:
Tighten it 'til it strips then back it off half a turn.

I use the 4t mobile one and hi flo filters without ever having a problem. Also used mobile one in my last 2 trucks and never have had issues. I think its a premium oil.

In theory, Mobil 1 4T Motorcycle is supposed to be safer for your clutch, with Mobil 1 Auto having some molybdenum friction modifier content. In practice, there a lots of anecdotal reports from riders who use Mobil 1 Auto in their bikes with no issue.

Personally I'm happy with cheaper semi-ester JASO-spec, such as Motul 5100. I've actually been running an Australian brand JASO-spec - Penrite MC4ST - for the last 2 years because I bought a bulk purchase when it was half the price of Motul :)

Postscript - from Mobil website:

"Are Mobil 1 Racing oils compatible with a wet clutch engine?
These oils are not recommended for wet clutch applications due to their high level of molybdenum."

Another section lifted from the Mobil site, specifically about Mobil 1 Racing 4T 10W-40 for Motorcycles.

Mobil 1 Racing 4T 10W‐40 is designed for sport bikes. Most of these bikes have multi-cylinder/multivalve engines and use a common sump, which means the engine oil lubricates the engine, transmission and wet clutch. So unlike Mobil 1 for cars, Mobil 1 Racing 4T 10W‐40 motor oil has no friction modifiers, which could lead to clutch slippage. The motorcycle oil also has more phosphorus/zinc for enhanced wear protection at high engine speeds and high loads. In addition, Mobil 1 Racing 4T 10W‐40 has a high performance dispersant/detergent technology for better high‐temperature performance and engine cleanliness. Mobil 1 Racing 4T 10W‐40 is also offered in a different viscosity grade than Mobil 1 for passenger cars.

The message here is if you do use Mobil 1 Racing, make sure you get the motorcycle variant, not the one for cars.

I used to be indecisive, but now I'm not so sure!
