I use (and recommend to use) on my cbr 600 the Motul 300 V. It`s a fully synthetic product made
from coconut oil;you can easily recognize it for is typical apricot smell.
Here in Italy it cost something like 15 U.S. dollars a litre ,but it`s value for money !
It`s the more stable lubrificant at the high temperatures (in my bike only 0.3 litres burned
in 8000 Km [equal 5000 miles]) and it`s famous for its high anti-friction power.
Moreover it`s widely used in competion. A friend of mine works as a mechanic for the Ducati
Gio.Ca. moto Superbike team; They are sponsored by Elf but they use Motul 300 V for their
bikes !!! I have also heard a lot of good speaking about Mobil 1 over the internet, but
I don`t know anybody who has really tryed it here , and I`m not going to change my preferences
for now...
Need your comment ...
Have a look to the internet oil faq (Not my work)
