brother,
your car has been driven over 100k for sure.
Now solution is very simple.
Firstly, plz dont get so much worry about that voice coming from the engine. Because your engine is old and zic a+ is very thin oil for it. If you want to change this oil now, then its ok. Or if you want to wait and to drive 1k more before next oil change, even then its ok. It will not be dangerous.
But just for mind's satisfaction, better have it change asap.
your car model is 2007, so do not use any oil whose viscosity indication is starting with 0, 5 or even 10.
You must only and only choose the oil 20w-50.
do not use zic hiflow or havoline or shell or total or toyota, etc.
As per my experience, presently best available oils in 20/50 are
PTT Performa.
Red color oil. Very dense. Very cool and very much dominant among all other companies.
Find it and it will cool your engine like ice and will shoot dead all unnecessary voices coming from your engine.
2nd best option is SIM3 (20/50)
Its malaysian oil and is good for the weaker engines.
After using 20/50, if you satisfied with the functionality of your engine, then next time you will have two options.
either keep using Ptt performa or SIM3 continuously. Or use Liqui Moly's 20/50. LM's oils are bit expensive, but very durable n reliable.
Gear oil of kixx is ok.
But can you post the picture of the bottle that you used? Because your car is automatic but its functions are not CVT.
Hence CVT gear oils are not recommended for your car either.
