Bro, i know this, but I don't believe quality of taglon now, white box is crap. Liqui moly will get black as well. Taglon was good when it used to come in silver box.
Check sediments in your oil at 5k kms, there will be some small solid particles in your oil when you check it with finger, and also vvti sound of tik tik went away at cold start.
Also, the acea approvals of taglon are somehow missing and there is no record of this oil internationally. Also, car looses acceleration at high rpms on this oil after 4000kms. I compared condition of my 5000kms driven oil filter with @makhdoom123 grande's LM 5w40 6500km oil filter, and his oil filter was way better in condition than mine.
Taglon is just there for warranty, and its just an average oil. I will personally review LM 5w40 after driving on it for few 1000kms. Viscosity of hot oil during drainage should be thicker, but taglon comes out like water; even though its 5w50.
Issues i faced with taglon are: one or two tick tick of vvti at cold start, and sediments at oil drainage with watery thin oil.
