You may be right, but that should not be the case. The SAE weight ratings are based on a standard and as such, the flow rate of oils with the same viscosity rating should be essentially the same. If not, then the entire point of the standard is lost.

My reading - so far - suggests that the 10 - 40 type system has been rendered somewhat obsolete by the synthetics. A 10 - 40 synthetic would likely be a true 40 weight oil but would still pour way below the temp of a mineral 10 weight oil.

Initially the manufacturers were reluctant to put 0 - 40 on a container because people would think it too thin. They seem to have overcome this reticence?

Things are a little dif in US, SAE controls standards BUT did my own tests,in freezer, well not me but two cups of oil, one petroleum, one synthetic. WOW! pet was like grease syn poured, exept for Syntec, which we dont use?..........lookin further Syntec is not a real synthetic. Amsoil seemed to pour best, but i am biased, been using it for over 30 years. Feris good one on the "Castrol", here its Mobil 4T. Double checked hand book, says 10-40 or 20-50. O i new a guy who used 5-50 in his HD,blew his mains at 34000 m. O called Triumph US.......not Canada, they still think we live in a Igloo here, "If you use 5-40, and have aproblem, we do a oil anaylis, no warrenty"

Based on my "research" only Mobil 1 and Amsoil are true synthetics anymore. Castrol and others that call themselves fully synthetic are actually class III oils based on fossil crude. They do this because this is cheaper and gives them a higher profit margin. Personally, I will continue using Mobil 1 as the extra cost every 6000 miles is no big deal. About $36 for 3 liters of Mobil 1 compared to $18-25 or so for conventional oil...not a biggie to absorb! Less of a difference between Synthetic "car" oil vs synthetic "motorcycle" oil. In my opinion, and not trying to be a smart ass, but for a difference of no more than $25 every 6,000 miles...I think it speaks for itself.

Hi there to all ,

sorry for interrupting and forgive my English...

All I wanted to say is what my father used to say (he was fixing internal combustion engines since the 50's ) :
''Oil is like blood for our body , so important ! So change it as soon as you can !''
...more mileage intervals are marketing bull...
Too many parameters there and conditions vary to standardize
(driving style , temp , gear changing freq , load , engine wear , terrain , driving style once again , etc).

Anyway , we (for some lifestyle reason...) are happily willing to spend some extra bucks in cheap alcohol in a bar - or on some fancy after market stuff that makes our bike (...us...) look ''unique'' - but are skeptical or tight on a better and more expensive product ( I often fall into this , ... bad habit ).

I repost a few links (posted some pages ago) for some interesting info in there :

http://www.ducatimonster.org/forums/...tor-oil-2.html

Thanx for your hospitality .

My best riding wishes to all .

Use oil without friction modifiers and change the oil and filter on a regular basis. Nothing else really matters much on a street bike.

I just did my first oil change on my 2011 S3 that I bought used in October. I decided to go with the Mobil 1 4T to see if the clunking in the gears gets a little smoother. $60 oil change is an wallet opener for sure. I used Rotella T6 in my C14 but want to see if I notice a difference with the Mobil 1

So how is the clunky gears going with the mobil 4T?

I have noticed a marked improvement in my 2010 S3 since changing to a full synthetic 10W40 oil. Previously I did have Motol semi synthetic 10W50. I also recently fitted the bike with Arrow slip-ons and remapped the tune using "tune ecu". Now I know some may dispute this, but the idle is now slower and the gearbox definitively is much smoother. I put this down to slight loss of power down low giving the engine a much more predictable power at the low revs used in traffic. Higher revs never were a problem anyway and now it goes even harder. Maybe its just that growl that takes your attention away? Works for me!
