Agip 10w-60, Motul 300V 15-50 or Amsoil 20-50

[aircooled]

Agip 4T racing 10W60 is factory recommended for the MV Agusta motorcycle I'll be picking up soon, (910cc, 144hp) they also say the Motul 300V 15-50 is acceptable. What about Amsoil 20-50? Whatever oil is used, it will get worked hard with the wet clutch/shared tranny on this bike. Any insights?

Go with the factory recommendation...I think you will find this is solid oil; my second choice would be the Motul.

Found some info from another section. http://alis.eni.it/alis/docs/schede/agip/in/IN542.pdf

Does it require a non friction modified oil for the wet clutch?

 

[aircooled]

Yes it does. The JASO MA rating takes care of that and most heavy oils do not have friction modifiers in them. I wish I could get some more detailed info on this oil. HTHS etc.

The Agip 10W-60 should have a HTHS guesstimated at around 6.5 to 7 at 150 C using the values from the Motul 300V. The Motul 300V 15W-50: HTHS viscosity at 150°C (302°F) ASTM D4741 5.33 mPa.s VI is 154 Motul 300V 20W-60: HTHS viscosity at 150°C (302°F) ASTM D4741 7.17 mPa.s VI is 162 The Motul data is from: PRODUCT SPECIFICATION PDFs
