Who is running which and why. Assuming full synthetic with PAO as the base oil content.

I'm running this as well in both of my 848 and MTS1200S.

As a side note, YMMV, but Autozone has a special deal on: 4 x 1QT full sync Mobil 1 oil plus FRAM motocycle filter for $34.99. I picked up 8 1QT bottles (no filters since I use OEM and/or K&N) over the weekend. Saved $20 :)

I did Motul 300V 15/50 at the 1K, 6K, 12K miles. Dealer did 300V 10/40 at the 15K service (done at 17K). I was on a long trip and figured I could make it an extra couple thousand miles without any issues. Where I live I can really run either... Sense it is cooler this time of year, I was fine with 10/40, but I'll use 15/50 in the heat of the summer probably.

10W-50 is what I understood to be recommended for this bike.

I have personally ran my bike in 114 degree weather with 10W-50 with no problems. I not going to try my luck with any other weight oil.

Like said before this is a hot running engine needs that extra protection especially in summer.

After I made this stop to take the pic, the Air temp moved up 2 more degrees.

Mine will go up to 212 water temp and stay there if sitting idling for very long, even in 40 - 50 F air temps. Somewhere between 200 and 212 is probably the threshold temp for fan activation. But, I used to have a Corvette (1995 model) that would rise the water temp to 230 deg at stoplights etc., before the fans would switch to high speed mode. They came on at 212 - 217 if I remember right, in low speed. Perhaps not an apples to apples comparison, but the car was spec'd for 5W30 synthetic and had no oil cooler.

With all the sophistication of the Multistrada (within the motorcyle realm) and its information rich instrument readout, I don't understand why Ducati did not include an oil temperature gauge and corresponding readout on the panel. It would be some handy info to have on tap. Oil temp is better info to have as far as when its safe to start cracking on the throttle after X amount of time after start-up and moving off, etc., than the water temp reading. I.e. oil temp a better indication of lubrication state of the engine than water temp and you don't want to crack on it until the lubrication state is optimal.

My ZX14 was a hot running bike as well as my RC51. The side radiators work fine when moving but at low speeds, forget it. I ran water wetter in both and it helped. We have days down here that routinely get over 100F with heat index. So I'm going to run the 15w-50 when it's time. Seeing the last pic from motorider makes me think these bikes don't run near as hot as my 14 did, guess I'll find out this summer.

I think this is very wise. I really think it now, after finding tech data on Shell Advance Ultra 4 15W-50 synthetic.

See attached Product Data Sheet, granted we can't get it in the states, but have a look anyhow for the sake of seeing the Typical Characteristics of the specific 15W-50 Ducati recommends via the frame sticker.

That was a "While moving Engine temp" of 206 degrees @ 70mph.

When stopped the bike temp shot up quickly and the fan kicked in.

170ish is the norm for my bike sub 100 degrees air temp and moving.

114 was the Air temp that day that moved up to 116 once stopped.

...just to clarify

206 degree engine is hot to me and uncomfortable to be straddling between the legs on a summer day sitting still.

So bottom line is if your going to see Air temps like I have... I recommend you stick with what Ducati specifies in the manual, U can see it works as designed.

Agreed. Not unusual to see some summer highs up to 100 degrees (F) here. I have 15w50 in now (dealer 1st service), Spectro Platinum 4 Synthetic which uses a PolyAlphaOlefin base stock with ester and probably some aklylated naphthalene base as the additive package solubility agent(s).

hi to everyone...

I was thinking, how does the oil grade influence the clutch? I mean, 2 bikes with the same oil in the same weather, but different oil grade like 10w40 and 15w50, how will their clutches behave? Which one will drag more for example?

I know how oil grade works, but can't really figure out how grade influence the clutch... :confused:

I stick with Motul
Got some 300V 10 W 40 cause it was on sale will change to heavier weight as summer rolls along...
Like to stick to same brand , and It doesn't get stinking hot often up here...

Just got my 2013 mts back from first service. The dealer filled it with Red Line Full Synthetic 10-40, 4.5 quarts. New filter and all associated orings/gaskets.
