Apart from prolonged engine life and generally better fuel economy, (offset almost completely by higher servicing costs), what are the advantages behind buying a less powerful diesel donk over a higher powered petrol one? I know they are torquier off road at low revs but given I will be 90% on road (kilometre wise, not time wise), would the petrol be a better investment? Will be doing some towing (camper or boat), some off road, but mostly on road, looking to keep vehicle for long term (250 000 - 300 000 kms).
Cost of engines is identical when new, so purchase cost is not an issue in choosing.
Had a trawl through all available reviews etc, but hard to find a good argument about pros and cons of TD vs Petrol.
Advice from those in the know appreciated.
