It is always beneficial to remove as much of the dirty engine oil as possible when changing your engines oil but refilling the engine with a fully synthetic engine oil like the 300V will not cause any problems if some of the old petroleum oil was left in the engine.
Synthetic motor oils and petroleum motor oils mix together nicely. In fact, that is exactly what the "Semi-Synthetic" oils are made of. Quite a lot of the regular petroleum oil and some full synthetic oil. (Enough to meet Government regulations.
)
As for the amount of oil you will need, that depends largely on the age of your Royal Enfield.
The UCE engine prior to 2013 had two oil drains.
One is the large hexagon plug on the bottom of the engine, towards the rear. The other is the oil pump inlet screen (filter) cover. It is held to the bottom of the engine with two small hexagon bolts.
Sometime around 2014 or 2015, Royal Enfield added another drain plug to the bottom of the engine making a total of three drain locations.
This new plug is located towards the front of the engine on the bottom of the crankcase under the crankshaft.
The reason for this added plug is that with only two drains, a considerable amount of oil was left in the engine right under the crankshaft.
This area of the engine is designed to hold a supply of oil so the flywheels on the crankshaft can throw it back into the transmission on top of the gears. That is what lubricates the gears.
By adding this forward drain plug the accumulated oil in this area can be drained.
If your motorcycle only has the two drain locations, 2 liters of oil will be more than sufficient to refill the oil tank. In fact, I've found the oil quantity of oil needed to refill my 2011, 500cc, UCE engine is 1.7 liters.
To use the sight window, you will need to start the engine and let it idle for at least 15 seconds. Then shut it off and allow 1 minute for the oil in the upper part of the engine to drain back down into the oil tank.
At this point, you can use the sight window to see if the oil is at the proper level.*
If your engine has three drain locations, 2 liters of oil should fill the oil tank just about right.**
A word about refilling the engine oil if the engine has three drains.
If you have drained all of the oil out of the three engine drains, replaced the plugs/cover and refilled the engine, the real oil level won't show on the sight guage.
That area under the crankshaft will not refill until the engine has been started and allowed to run for 30 or more seconds. It receives all of its oil from the oil pump so running the engine is the only way to refill it.
When it refills, the oil level in the oil tank will drop.
For this reason, the proper way to refill the oil tank is to add the 2 liters of oil and replace the oil filler plug.
Then, start the engine and let it idle for at least 30 seconds. One minute is better.
Then, shut off the engine and allow at least 1 minute for the oil in the upper part of the engine to drain back into the tank.
Only then, can you use the sight guage to determine if the engine needs more oil added to bring the level up to the center of the sight window*.
*The Royal Enfield oil level guage (window) can only be used if the motorcycle is resting on the center stand on a totally flat, horizontal surface.
If it is leaning either to the right or to the left, the oil level in the sight window will not reflect the actual oil level in the oil tank.
** The Owners Manual says the engine needs 2.75 Liters of oil to fill it.
This is correct for a
totally new or rebuilt engine
but about .65-.75 liters of oil will remain in the engine after a normal oil drain. This trapped oil is in the side covers and other nooks and crannies and it will not drain out by simply removing the drain plugs.
