@Mun33b Alhamdulillah the car is running lovely now apart from the sound which I have parked it cause of and shall take it to the mechanic whom someone guided me to above with the Reference of Raja Ahmed Mujtaba from youtube who had his car fixed from as well (Engine replacement) the guy was humble enough to guide me that he would seek out the parts (if needed) with me himself. As for the rest the car feels really responsive, a few more changes that I did were replacing the air filter with the oem oiled air filter, the oem oil filter and an oil change, throttle body cleaning, fuel pump service and now all it takes is a slight touch upon the pedal for the car to instantly thrust onward.
Out of curiosity, the care person where I had the oil change from suggested shifting to the original company specified 5w30 Oil for it instead of the 10w30? For a lighter and slightly quieter feeling engine, I asked him to pour in the 10w30 i've been using but thought I'd ask for your advice cause I didn't think it would be wise to do so. Apart from that there were also recommendation to get Mobil1 for it or LiquiMoly lol everywhere, everyone seems to have an opinion but I know better now thanks to you not to trust these local workshop workers.
Is it advisable to use the 5w30 Oil with 130k Kms on the odometer?
Also the oil from Mobil1 and LiquiMoly? Does it make it so that the car requires oil changes at a later interval in exchange of the price? And is it worth it?
