Fuel adulteration has reached acute levels as the Nepal Oil Corporation (NOC) has failed to monitor the quality of fuel supplied in the market.
Senior technicians at workshops of leading motorcycle distributors said incidences of engine damage caused by adulterated fuel have risen dramatically over the past two months.
"Some 50 percent of the three dozen bikes we service daily have problems caused by contaminated fuel,' said Mukesh Lamichhane, technician and operator of a garage in Anamnagar.
