MA or MB oil grade issues?

[masterrch]

I have been running Motul 7100 20w50 in my '07 1098 for the summer,for the fall(cooler temps) I decided to switch to a 10w40 weight since it was due for a fluid change anyways,while at the dealer they didnt have any Motul 10w40 they only had Redline 10w40 motorcycle oil.I run Redline in my car so I decided what the hell.
After changing the oil I looked at the bottle and saw it was a MB rated oil not MA like the Motul,freaking out I called Redline and the tech support dude told me that the MB rating means it has more friction modifiers than MA and should be just fine,but he also stated I should use 20w50 for the desmo valve train.

1)anybody have issues w/MB rated oil?
2)anybody run 20w50 in colder temps?

Oil is a sore subject with me.

Motul V300 or nothing else... here is why.

The V300 has a double ester formula. Ester is the stuff that keeps the oil stuck to metal. In most vehicles, that doesn't make a difference, but with the desmo, you want the oil to stay planted, so you don't have to worry about cold starts.

Also, you wanna use 10W40 on a Ducati Superbike. The 15W50 or 20W50 has WAY too many additives. 10W40 V300 is one of the best oils made, even in the Amsoil tests, on most of the testing its #2 below Amsoil... which says a lot because Amsoil is the best there is.

Anyhow, there are many guides to what the symbols mean on the internet. I wouldn't trust anything a dealer says. I beat the living shit out of my race motors and only use one oil. So when I take them apart and see zero wear, I know the oil is doing its job. I don't have to guess based on the marketing.

To add to this, the desmo valvetrain does not require a 20W50. Don't know about too many additives, but it's too heavy. Ducati has never recommended a 50 weight oil in any Testastretta or newer motor. You should be using a 10W40 all year, even need the most extreme summer racing conditions. Who ever told you this is clueless. Don't take our word for it...look in your own owners manual. Sounds like you haven't done that. Don't use the chart either, read the paragraph for recommended oil.

And like Tye said, Amsoil is the best and you can get it from me any time you like.

I run Amsoil 10W40 (and filter) in all three of my bikes and change the 749 & SS once a year and the Multi every 6,000 miles.

thanks for the input
I should be ok till I can scrounge enough money together to change the oil and filter again though right?the redline oil meets all the SG,SJ and SH ratings,
why dont you use amsoil it seems to be alot cheaper than 300v?

Doesn't your air cooled 800 SS call for 20W 50? My older 900 SS does call for that weight until the outside temperature is below freezing. I don't ride then, so it doesn't matter to me. Air cooled engines have larger clearances which I believe is the reason for the heavier oil.

It's 300V, not V300... It is a fully synthetic oil, so that's great. If it has a very high film strength, that's also very good for motorcycles.

20W50 doesn't have any more additives than 10W40, as far as I know.

It's really hard to get any information from Motul since they don't have a US web site.

No, my 800 calls for 10W40. So does the air cooled Multi. Ducati switched to tha around '03 or '04. The benefits to running as thin of an oil as the manfacter calls for are numerous...cooling, drag, efficiency, etc, etc.
