Hello, I own I20 Active Diesel and had 1st oil change couple of months back. My friend has an oil shop so while visiting him, he advised me to pick up a bucket of oil as it would save me good few hundred bucks. He made a call to his cousin who works in hyundai in a different city to confirm oil grade 15w40 Shell Rimula R3x will be ok after I told him the grade suggested from the manual. He said that will be perfect.
So, after that I went to get my car serviced for 10,000km schedule. I handed oil to the service guy but they refused to use it. They told me that this is not for cars, its for heavy vehicles like trucks. They use 5w30 grade only for diesel engine. I told them that Hyundai's website is suggesting 15w40 for diesel engine and 5w30 for petrol, how can you not recommend it? They didn't trust my word, so I showed them oil recommendations page on hyundai's site. After that too they said, well we don't use this grade, and if you want to put this oil, we will not take any responsibility later on if any issue arises. I didn't wanna argue and asked them to use their oil. I knew they were wrong.
Now, I feel car is engine has little more noise and its not smooth as it was. Even my bike feels smooth when oil change is done, but car doesn't give same feeling.
I read that this can be caused due to oil grade only. I have emailed hyundai customer care regarding this and asked them how can service centers not follow your recommended grade, they are yet to get back with me.
Does it have a long time effect on engine? Thanks
