Before we start let's first look at some of the most frequently asked questions related to engine oil for Royal Enfield. 

Frequently Asked Questions

Q. Is synthetic oil better for Royal Enfield? 

Synthetic oils are always better than mineral oils as they last longer than mineral oils. Synthetic oils are designed to meet consumer demands and outperform mineral oils. 

Q. What is the life of Royal Enfield engine oil? 

The life of Royal Enfield engine oil depends upon the engine oil that was previously used in the vehicle. 

If the previously used oil is a mineral oil it should be drained in 2000-2500 km period while in the case of semi-synthetic engine oils, it should be around 3000-3500 km

Typically, the drain interval for fully synthetic oils like Motul 7100 and Liquimoly Street Race is 5000-6000 km.

Q. How many litres of engine oil is used in Royal Enfield? 

The engine oil capacity of the Royal Enfield UCE engine is 2.5 Liters. (2500ml) 

Q. What is the recommended viscosity grade of oil for Royal Enfield? 

The grade specified by Royal Enfield for the UCE Engine Royal Enfield bikes is 15w 50.

The old Royal Enfield bikes have a viscosity grade of 20w 50.

However, if you want to use engine oil that is 100% fully synthetic, you need to go with the 10w 50 grade of oil. 

Q. Should the engine oil filter also be changed along with the engine oil? 

Yes, it is always better to change the engine oil filter along with the engine oil. This helps remove soot and dirt particles from the engine and thus increases the effectiveness of the new engine oil. 

Q. How do I know when the engine oil on my bike needs to be changed? 

After every 500 km, the engine oil level should be monitored. It should be topped up with oil in case the level falls. 

The oil also needs to be checked for stickiness. Check the stickiness of the oil with your fingers, if it looks sticky that's fine, but if it doesn't, it should be changed. 

The condition of the oil can be determined by the colour of the oil itself. If the oil has completely turned dark and smells, it needs to be replaced.
