Just a quick survey before I open another topic for discussion
What oil do you use in your Paso ?

Mobill1 10-40 moto oil usually. Good for a few more HP due to less pumping loss. 20-50 when I don't have 10-40.

Fully synthetic Shell Advance Ultra 4 15W-50. No anykind oil problems.....

In the past I have used AMSoil in my two wheeled vehicles and Durablend in the 4 wheeled(4X4 FRONTIER AND XTERRA).
Both of these oils are getting harder to find all the time and with my work schedule it seems I always forget to order it ahead of time.
The 907ie needed an oil change now,as it was a quart low and I never changed it out to begin with( yeah I am still on five year old belts as well and even older tires ) no time to get the AMSoil I usually use.
So...I went with the Mobil one 0w40. I've been seeing some good things with the 0W40 and 0W30 oils. Amazing things actually Engines with over a thousand hard hours on the dyno that even the cams look brand new and that is very unusual indeed
AMSoil because they manage to get the proper viscosity with far less polymers than other oils.( That I have tried anyway, 35 years of tearing down engines and trannies on just about every vehicle you can name )
Less polymers is good,less zinc is also good. I realize a lot of folks insist on racing blends for their street bikes. The issue I have with racing oils in bikes that are not used to race is the zinc content. Zinc means sludge,polymers also mean sludge. So unless you are pulling your engine apart on a regular routine racing oils are not a good thing period. So anyway I am taking the plunge, a big leap of faith with anything from Mobil ( I do appreciate your response on the subject Jon, not to diss the rest of you that responded )
Again thanks to all of your input
So let the discussion\rebutals\expression of opinion begin

I've always used the ducati recommended 20-50w but with the advancements in technology over the years I would like to know if there is something better I could be using.

Higgy,

Stick to the moto oils. They will stand up much better to the beating the trans gives it compared to auto oil.

Don't have a Paso, but I do have a 750 Sport. I follow all of the topics with great interest. I have been using Lucas 20-50w synthetic oil. It was not one of the oils listed in this thread. Anyone know about lucas oil?

An updated report on Motorcycle oils,sponsored by AMSoil but still an accurate account
No Lucas oil info,but from what I know about it Lucas oil is a decent quality oil that has been around for a while I believe it had its roots in the dirt track racing which means they have a lot of experience with high heat and high loading

PS sorry Jon,the last 30 years there are a lot more auto's running around with motor oil in their trannies than motorcycles ever built . It really comes down to resistance to shearing forces that makes a quality oil

I've heard of Lucas oil and went to the Lucas mile while in Indy this year. I think they are located in Indy (Lucas Stadium where the Colts play) and have stuff for the trucking industry too.

I don't think they make Moto oils but I don't know for sure.

Can you spell Honda? Chevrolet? Ford?
There's a few for ya

Who'da thunk it.....
