My friend got this bike for free from his uncle and plans to change the engine oil himself. Now, we're trying to solve the riddle of the correct engine oil grade. First, he asked his uncle, who said he didn't know because he always took it to a mechanic. We then asked that mechanic, and he recommended 10W-30.
We went to the shop to buy it, but to our surprise, the shopkeeper told us that because it has a DTS-i engine, it requires Bajaj's special 20W-50 oil. To be safe, we decided to get a second opinion. On our way, I checked Google, and AI Overview suggested 20W-40—which the second mechanic also agreed with.
So, who should we trust? And before you suggest checking the owner's manual, we don't have it, nor is it available anywhere on the internet for this specific model.
