ive tried
SHELL HELIX ECO-10 (10-30) completely shit...
ROYAL PURPLE (10-40) loss viscosity at about 3500KM shit...

now back to

GENUINE HONDA OIL "FEO" think i will just stick to this..

ive been told not much oil can put up with 9000RPM.. and last the duration it is expected to.. so that explains it...
