Royal Enfield Classic 350:Engine Oil Grade
Most Royal Enfield bikes with 350cc engines are equipped with 4 Stroke Air-Oil Cooled J-Series Engines. These engines require the same grade of engine oil. However, checking the user manual before refilling the engine oil is better. The engine oil grade required in Royal Enfield Classic 350 is SAE 15W 50 API SL Grade JASO MA2 Semi Synthetic. The brand recommends the usage of Semi-Synthetic engine oil, but you can also use the same grade of synthetic engine oil as it is better than the semi-synthetic oil. In addition, JASO MA2 means that the engine oil is suitable for bikes with catalytic converters in the exhaust system.
Engine Oil Capacity of Royal Enfield Classic 350
The engine oil capacity of the Royal Enfield Classic 350 is 2.2 L; however, this is the capacity of the dry fill. That means when the engine is manufactured or when the engine is rebuilt; it requires 2.2 L of engine oil. You need approximately 1.7 L of engine oil when carrying out the maintenance oil change. The actual engine oil packaging may be more, so you must carefully measure the engine oil before you pour it in. You may overfill the engine oil if you use all 2L in the pack. This may lead to reduced performance or issues with the engine of your Classic 350.
