I've struggled to find a supplier of the correct fully synthetic Agip 10W60 oil, however this place will send it:

http://www.motoworlduk.co.uk/racing4t10w60.html

Good service and it arrived the next day.......however it is VERY expensive at £12.75 ltr (= £51 an oil change!!).

Maybe I should have bought an MZ after all!!!!

.....or does anybody else know a cheaper source??

No need to use 10/60 oil as 3X and everbody else uses10/50 Morini themselves have said that this is acceptable and not to bore everyone with specs ie sheer properties, rpm at a given temp, or just go to opie oils to get the knowledge.
So save the pennies

Sorry for the ignorance - what is the downside in using 10w/40 which is readily available from all motor factors and £30 for 4Litres? 10w60 is impossible to find and 10w50 is difficult to get hold of.

Im about to do an engine oil change on my Corsaro ...

For this country and the temps we see, also if your NOT using it on the race track using a GOOD quality fully synthetic 10/40 with a jaso ma and double ester based spec should be NO problem there are quite a number to choose from depends who can supply in your location, but Putoline ,Motul Castrol Power 1 and Silkolene pro4 are all good brands.
Please look at this site for answers to tec specs etc so you can be certain of which and why as these guys are the specialists www.opieoils.co.uk they will also answer any questions by E-mail

A good 10W40 is of course cheaper that a 10W50 or a 60 if you can find it, and will do fine. If concerned change the engine oil more frequently.The only significant difference is in the oil,s shear characteristics under extreme conditions: ie Heat and it,s ability to maintain it,s viscosity and longevity.Additives are another way to go as well for use in the cheaper oil,s. Try www.trubluoil.com.au Engine Oil Stabilizer, this product is excellent and is the slipperiest substance I have rubbed between my fingers.

Sorry Guvo
You should NEVER use friction modifiers in motorcycle engines due to the use of wet clutches plus they can have a detrimental effect to the running of an engine with engine start failures, a rough running feel and increased fuel consumption due to higher engine stall speeds.THE ONLY oil used in a motorcycle engine shopuld be to the JASO-MA spec which has (no friction modifiers) or JASO-MB (with friction modifiers) but is designed for motorcycles that need that spec. If anybody wishes to read further on this matter the report is published at http://www.smartsynthetics.com/articles ... _facts.htm

Steve 55.Sorry,I should have made my self clearer,the product is not a friction modifier even though it seems extremely slimy when rubbed between one,s fingers. Tru-Blu Engine Oil Stabilizer has been used by numerous motor cycle racers & riders for years in Australia with wet clutches with no negative effects.Please feel free to email the managing directer Murry from a link in www.trubluoil.com.au or peruse the tru-blu Oil web site at your leisure , they have top products including their upper cylinder lubricant which one adds to their fuel tank,which will improve consumption by up to 30% quote ,unquote.

I have visited the Tru-Blu site! It never ceases to amaze me that intelligent people are taken in by these claims. It's all smoke and mirrors. Companies like STP, Lucas, Molyslip market similar products. Tru-Blue claim and I quote "the oil better maintains its ability to cling to" and "metal parts are coated with a thin film of oil" this is a FRICTION MODIFIER by any other name.
As for their upper cyl lube which they claim will enhance fuel economy by 30% is complete bollocks it's just an octane booster, using a super unleaded like Shell V max fuel will have the same effect.
Some racers!! Use these products because the friction will be less so the engine runs cooler and marginal gains to RPM but they only have to last for ONE meeting.
If you are looking for more power and torque use thinner oil!!
In conclusion always use premium brand oil specified for motorcycles.
I personally would not have a problem in using 10/40 Jaso-Ma spec full synthetic ester based oil as mentioned.
