(2) Beyond 100KMPH with A/C OFF I am loosing accelaration
very drastically and hearing huge knocking sound.
So far, milage is very good HIGHWAYS-18 with A/C OFF.

Hi,
The problem could be due to misfiring, recommended to check the ignition system ie timing, spark plug connectoin, etc and also fuel supply system.

In your next service do the following:
1. engine de-carbonization
2. IAC valve cleaned or replaced
3. Air filter cleaned or replaced
4. Oil service use only synthetic oil no mineral based should be used
5. clean spark plugs, replace if necessary(you should change spark plugs once in 2 years) and adjust timing.
6. try iridium spark plugs....BOSCH brand is good

The problem is in engine oil filter.The oil filter is jammed because of which the engine oil is not reaching towards the engine from the chamber.This results in jerks and rapid loose of acceleration beyond 100khmphs.replace or service it quickly or it will result in engine failure.

Must be the engine oil filter as mentioned. An authorised dealer service should settle the diagnosis and treatment. Doesnt yet seem time for an engine overhaul.
