I’ve been using a BS4 Yamaha MT-15 since 2019 and am now planning to upgrade. My daily office commute is about 25 km, and occasionally I do a 540 km trip. I’m looking for a comfortable and reliable bike with reasonable fuel efficiency.

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.

Since you're looking at just a small upsize in your tyre sizes, you can go ahead and replace the tyres of your Jupiter with 100-section units from the stock 90-section ones. It will help give you more sure-footed handling as well as a slight improvement in ride quality. The flip side to this change will be that wider tyres will increase rolling resistance, which is going to have a small but noticeable negative impact on fuel efficiency. Another point to bear in mind is that the scooter's steering will feel heavier in general, but especially at slower speeds.

The Triumph Scrambler 400 X that you have shortlisted is a good one bike to do it all. If you have your heart set on it, you should indeed hurry up and get one soon before the 350cc replacement is launched in the coming months. While its slightly smaller successor will be identical in most ways, the smaller engine with likely reduced performance could affect performance at highway speeds. So it's better to go for the 400cc model while you can. The TVS Apache RTX 300 is another great all-rounder, and if you are ready to deal with its size and weight, then you should absolutely consider it. Do bear in mind that for someone of your stature, the RTX could prove to be a little much inside the city at slower speeds. So we would recommend a thorough test ride before you make a decision. Another option worth considering is the Royal Enfield Guerrilla 450. It has a very approachable 780mm seat height, which will be helpful for you and has good performance and comfort for both city and highway usage. Since all the bikes you're considering are quite different, take a test ride of each before making a decision.
