"As soon as diesel becomes 30 cents per litre more expensive than ULP that's the cut off point for diesel being cheaper to run a vehicle. Especially if you are towing a van ... the type of vehicle you drive obviously makes a difference but I used today's prices ($1.41 ULP ... $1.69 diesel) and ASA fuel comparison figures for a Prado in both diesel and petrol. Worked out that over 20000k's of use (12000k of towing which is what we do) the diesel engine would cost just under $300 per year more than the ULP motor.
'Fuel' for though for those wondering what motor to get next."
