jschaf Posted July 14, 2018 Report Share Posted July 14, 2018 I think Ducati probably did some intensive research on the subject. Why do you question their authority? 1 Quote Link to comment Share on other sites More sharing options...

Why do you question their authority? 15 cold viscosity seems too high for Ohio weather. Dealer used 10W-40 Motul 300V. I’m leaning towards the same, but wondering why Ducati would recommend 15W-50 as a blanket recommendation. Generally weather temps play a role in viscosity selection, right?

MidgetTodd Posted July 14, 2018 Report Share Posted July 14, 2018 KTM is 10-60. Has to do with tolerances and return passages as well. Im confident they've done their homework Quote Link to comment Share on other sites More sharing options...

vf1000ride Posted July 14, 2018 Report Share Posted July 14, 2018 (edited) Shell Advance 4-T comes in a 15W-50. I got mine at the Advance auto in Reynoldsburg. I have used it in my Multi as both the workshop and the owners manual only call for a 15W-50, they don't have a temp range chart like the other bikes. All my other Ducati's and when I had the Triumph all got regular 10W-40. Edited July 14, 2018 by vf1000ride Quote Link to comment Share on other sites More sharing options...

This is the correct answer. The Duc engineers are considerably more educated in this matter than we are. Especially the OP. Quote Link to comment Share on other sites More sharing options...
Tonik Posted July 14, 2018 Report Share Posted July 14, 2018 That said, read the manual again and make sure there are not temp ranges included and that you actually read it correctly. It does seem odd for our temp range. Quote Link to comment Share on other sites More sharing options...

Cuz that is when the lower number comes into play. Guess what the W stands for. It's the 50 that should be giving you pause. Quote Link to comment Share on other sites More sharing options...

2talltim Posted July 14, 2018 Report Share Posted July 14, 2018 I wouldn't mess with the top number if they say run 50 I'd run 50. The bottom or cold number can vary based on climate. I run 5-40 in mine that calls for 10-40. Even in summer month it helps with my timing chain chatter. Quote Link to comment Share on other sites More sharing options...
JustinNck1 Posted July 14, 2018 Report Share Posted July 14, 2018 Yamaha says 10w40 or 15w50 for my MT. Rotella T6 5w40 is working fine. JASO-MA/MA2 certification is enough for me. 1 Quote Link to comment Share on other sites More sharing options...

jacobhawkins Posted July 15, 2018 Report Share Posted July 15, 2018 (edited) Only thing I can add to this thread is that Ducati used the same oil filter for every bike, except for the Pani, since the mid 90s. Good job, engineers! I did an OEM oil change last time for Izzy before three track days and one serious street ride with @ChristopherHawkins and it worked well for me, but at $80, I'll give my old standby (Rotella T6) a try next time. P.S. That's right three track days on a 19 year old Ducati with 64,000 miles. Time for a valve check! haha Edited July 15, 2018 by jacobhawkins 1 Quote Link to comment Share on other sites More sharing options...
motocat12 Posted July 15, 2018 Report Share Posted July 15, 2018 picked up some Silkolene comp 4 15w-50 at Iron pony today to humor this thread. Jaso ma2 synthetic esther based :shrug: $19 I'm not due for an oil change .Does used T4 oil keep? I could drain the current stuff and freeze it at 10W to use for later. https://www.amazon.com/Silkolene-600885885-Comp-4-XP-Oil/dp/B071L5M57G different new label?
