..I wanted to share my feedback after using armorol on my Himalayan 411.. i completed over 7k kilometers after the oil change. mostly highway touring done and i found huge improvement in the mileage, vib and heat levels.
Went to Ayodhya and Kashi from Bangalore last month (4k kms) and engine was chugging along like a charm.
got an astounding average of around 28kmpl.
