! ! Earlier they were recommending 20w40 . They made this change without any modification to any of the engines at all !! The current bharat-III mods are a separate chapter .
. When I inquired at the Authorised Service they said ( with usual reservations about warranty) I could use 20w40 mineral as well and yes 20w40 will keep my engine cooler in summers . So I am more or less confident about changing to 20w40 mineral , since my engine is overheating on longish runs and I like kool engines . There is no question of synthetics since I never use any synthetics on any of my bikes ever . Heck I don't even wear anything with any synthetics , even shoes .
. I am interested to know whats good and better and best among the minerals since you guys seem to have tested the whole market out so no point in reinventing the wheel .
