u/bhxgxthx

so my bike is a second hand hf deluxe 2015 model which has 50k+ kms on it.

when I want to change my engine oil,i go to my nearest workshop and they change it but they use local engine oil.

i want to buy a good branded engine oil and use it and know the difference between it.

which company's engine oil do you guys suggest?

is there any problem with using synthetic or semi synthetic engine oils?

i have little knowledge on these topics
