thank you for the reply.

looked for foam on dipstick, it is not there.

enquired with Service Adviser about the overfill oil and they said stated level is harmless,it will decrease little(small quantity) after some drive

And the oil is changed and filled as per required quantity specific to the Car.

I will get it removed ASAP.

I will also check how much more it is and why it was overfilled to prevent reoccurrence.

Check other variant of Carens Engine Oil requirements and figure out why your car was mistaken to be that one in the service center.

A FNG ended up using a 7 litre container instead of a 6 litre container for the XUV500 2.2mHawk. He didn't seem to think it was a problem. In any case, I removed excess oil using the Ryles tube and syringe method. Now the oil level is a little below the max level. I think it is fine. If top up is required after a few thousand kilometres I will do it. Here are some pointers from the Internet.

1. **Increased Oil Pressure**: Overfilling the oil can cause an increase in oil pressure, putting extra stress on seals and gaskets. This can lead to oil leaks, as the pressure forces oil past these seals and gaskets.

2. **Oil Foaming**: When the crankshaft comes into contact with too much oil, it can whip the oil into a frothy mixture. This foamed oil is less effective at lubricating the engine, leading to increased friction and wear on engine components.

3. **Reduced Lubrication Efficiency**: Excess oil can impair the oil’s ability to properly lubricate the engine parts. This inadequate lubrication can cause increased friction, heat buildup, and faster wear on critical engine parts.

4. **Engine Damage**: In severe cases, too much oil can cause a condition known as hydrolock, where oil enters the combustion chamber, preventing the piston from completing its stroke. This can result in bent connecting rods, cracked pistons, or even a shattered engine block.

5. **Catalytic Converter Damage**: Excess oil can find its way into the exhaust system, leading to fouling of the catalytic converter and potentially causing it to fail.

6. **Fuel Efficiency and Performance Issues**: Overfilling the engine oil can lead to increased drag on the rotating components, reducing engine efficiency and increasing fuel consumption. It can also result in poor engine performance.

To avoid these issues, it's important to always adhere to the manufacturer’s recommended oil capacity.
