It doesnt really matter with the 10W40 or 50. Penrite makes their 10W40 stuff with "an extra 10" on the side as a marketing gimmick.

The most important thing is that you dont have any friction modifers in it, otherwise your clutch won't work

i use sunoco motorbike full synthetic 10W50. IMO works better, ie no leaks, for the older MC22 engine

Motul make different oils (not just viscosity) so you haven't given enough info for us to work with, BUT, it sounds like your mechanic is bullshitting you (probably only had 10w50 in stock). The difference between 10w40 and 10w50 is how thin the oil gets when it's hot, 10w50 oil won't thin out as quickly as 10w40 when oil temperature goes up, but it also might be too thick during regular running in cold temperatures (I think you'll be fine though).

Yeah he said he had to order it in he uses mobil 10W40 but i wanted motul because i've read its better (only want the best in my pride and joy) for some reason he could only get 10W50 in Motul i didnt ask why. So 10W50 is thicker when hot so less chances of leaks being an older engine makes sense i guess and it never really gets that cold here for it to be an issue with running temps i wouldnt imagine. So theres dif types of motul oil, what type is best and i hope thats what he ordered cause its on its way thanx for help

It's not about leaks, it's about adequate protection.

http://www.linkint.com.au/motul_4_stroke_oils_page.html 5100 is their "standard" stuff and most likely what you're getting.

I wouldn't want the best in my engine unless you're paying for it... :lol:

I use Fuchs Titan Super GTO, full synthetic 10w40 with no friction modifiers and less than $10 a litre. GOOD oil and GREAT price.

Usually you get what you pay for so i figure its got to be more expensive for some reason. Obviously the bikes nearly 20 years old so its prob seen its fair share of shit oil and me spending the extra money on oil now prob wont benefit much but it will keep me happy knowing shes running on the goods

I switched to Motul 7100 10w40 a week or two ago. It's the full synthetic one. I'm a fan, no leaks, fixed an issue with my bike not finding neutral while turned on and not rolling. So i'll keep using it.

Ian, sounds like they adjusted your clutch.

If you want to look after your bike, frequent oil changes are better than expensive oil..

in your 250rr? i'm after another oil to compare to motul for an oil change coming up. haven't had a problem with it, but if i can still get good oil without the premium $, i'll be happy.

what with the 'no oil leaks'
most full syn oil will make your clutch slip on older bike especially the cibby , if it's not you're driving like a pansie.
recommend motul 5100

Oil technology has come ahead heaps since cibby was designed,
modern oil stays in grade heaps better, the helix or ball shaped molecules in the oil that open up when oil gets hot to make the thin base oil thick, and that get sliced up by mcycle gear box,
'viscosity index improvers' have become a lot stronger,

most manufacturers use the same ad pacs, additive packages, and friction modifiers aren't used for a variety of reasons, some car parts don't like them either,
so as long as you don't leave your engine idling cold, or lug in a high gear, and change it occasionally, use the cheapest semi syn oil, and send the balance to me
