Finally did my first oil and filter change, changed front wipers, and tried to change diff oils but abandoned the diff part as the front diff drain plug was too tight and could not crack it.
The site was not working for me so couldn't access the procedure from my previous threads so followed the project 200 oil change video step by step it took about 5-6 hours but successfully did it exactly as per the procedure with some minute errors.
it was an easy and simple process but it took time as I had to get the car on the ramp, arange axle stands, struggle to crack the bash plate nuts, then in between didn't understand some tools so left the car on ramps and went to Halfords to ask them etc etc.
It was super satisfying. I found out that if we fill the exact 9.2 liters as per owner's manual, the oil level is slightly more on the dipstick. I will remove little bit later. Now I know how to do it and also not expensive, I am planning to change the oil and filter every 3000 miles for few times until the oil appears clean.
I will buy some power tool to open these nuts. From the look of the bash plate nuts it appears they were not opened for long time and may be oil filter not changed as well in previous two services.
