Hey... Recently I had done servicing of my CB Hornet 160 R bike from the garage nearby me. The servicing mainly included checking brakes for both front as well as back tyres which got fixed up and there was a need to change engine oil of my bike. Since it was my second time for servicing I hardly had any idea about engine oil. My service mechanic suggested me to go for Divyol Spin X4 20W40 engine oil as he had been using the same for his previous Honda customers and so I agreed to do the same. Now I found my bike running at its smoothest speed without any rugged noise and giving perfect mileage. Please suggest me whether should I continue or replace it???
