Aoa Everyone. Need some guidance regarding engine oil. I'm driving 2007 Altis - 175k on ODO. Currently I'm using Havoline 5W-40 ProDS however, i have already added additional 800ml of oil only after 3000km from last oil change. Even though it is well within the suggested limit of this car but i m observing it increase in summers.
Should i consider switching to 10w-40 (shell H6) or switch to other brand? Any help would be appreciated
