Diesel engines are not so easy to find for light-duty vehicles in Oman

As a former British protectorate, finding some old Lister stationary engine once in a while is no surprise at all. Some fishing boats also rely on Diesel, but it's not so easy to see Diesel-engined light vehicles as it is for petrol-engined ones. It is quite surprising to find out Toyota is using its most modern Diesel engines for the HiLux instead of the old-school 5L-E nearly everywhere by now. As a general rule, most Middle East countries used to not enforce emission standards so strictly.
