I understand well that one is usually advised to go for petrol vehicle when the usage is less, because the extra money needed for diesel vehicle is not justified then. However, I always think about better utilization of the fuel and diesel cycle is understood to be more fuel-efficient. I did check this category briefly for this topic, but did not find any discussion, hence this thread. At least few years ago, diesel vehicles were known to be dirty, polluter, noisy and also costly to maintain compared to petrol ones. At many national parks, diesel vehicles were banned. I don't know if these are so even now. However, now it is a general impression that diesel engines have improved greatly and except for being more noisy than petrol, the negative things are greatly reduced. I went for emotion MJD after using petrol Indica for 9 years and though my usage is not high (19K km in 27 months), I am not repenting for buying a diesel vehicle. Experts on this forum may please comment and clarify.
