•6dI have been using a TVS Ronin for the past four months, and I am experiencing a heating issue. Would it be advisable to upgrade the engine oil grade from 10W-30 to 10W-40 to address this problem?

From a strictly technical standpoint, the higher grade 10W40 oil should theoretically help in hotter climates like ours because it will retain its viscosity at higher temperatures better than 10W30. Thereby being better suited to cooling the TVS Ronin's air/oil-cooled motor. However, this will likely void your warranty if it isn't recommended by TVS. We would advise you to stick to whatever the owner's manual and service advisors recommend, especially if your bike is still inside the warranty period.
If your manual or service advisor strictly specifies 10W30 only, or you ride mostly in cooler weather, consider switching to a fully synthetic 10W30 oil from a different brand instead to keep cold‑flow performance optimal.
But before you do all this, we'd first recommend a trip to the service centre to ensure that idle RPM is set as per the manufacturer's recommendation. Also, make sure to clean the engine’s as well as the oil cooler's fins and airflow path. Then, use the bike for a few weeks as you normally would to see if that has solved your problem.
