thanks devilskreed,
the my Cuore has clocked near 5500km just, u can say its new, i felt 15W40 a very heavy oil for it, as i read on different forums, Havoline is looking best choice in 5W40, will see this in summers (next change), in pakistan Mobil1 is not offering 5W40 but 0W40 & 5W50
due some posts on PW (rated Mobil1 is best of alll), i thought to put 0W40 / 5W50 in my new cuore, so that's why i want some suggestions will these ratings (0W40 or 5W50) will feasible for cuore or not.
