I will be changing the oil myself and looking into oils other than the Motul 300v 15w50 that the Ducati dealer uses.

I saw this Motul 5100 4T Synthetic Ester Blend Motor Oil is half the cost of that stuff they use.

What am I going to run into if I use the Ester Blend?

Wrong viscosities.

What do you mean? Ducati Beverly Hills puts Motul 15w50 in all their Hypermotards & Hyperstradas

Here are the specs for the 5100 4T 15w-50

The viscosities are very close. The VI is a bit lower.

Of those only the bottom one is in the right viscosity range. The 300V.

I wouldn't touch the 5100 4T with the specs you just posted.

Is the 300V MA rated? Doesn't say.

The 10-40 results are a good indication about the other motorcycle viscosities too. I have the 20-50 results somewhere too.

Price consideration was removed as it doesn't matter that much to me.

I was using the Mobil 1 4T oil in my race bike and was fine. Was considering using that in my 939 as well. Any thoughts?

Cool an oil thread.

I use Motul 7100 10W40. I've also used Motul 300V 15w50 and Mobil 1 4T 10w40. They all work fine, but the clutch engagement smoothness started really suffering after 3,000 miles on the Mobil 1.

RSL - these are tests done from Amsoil, right ;-)


my Dealer puts Castrol RS 20W50 in, I change to LiquiMoly or Motul 10W60.
The 10W60 lets clutch work much better and smoother.

Yes, the only source of ASTM test results.

Sure would be nice if other companies shared their ASTM test info.
