Currently driving a 1.5 TD van, I'm surprised at the variable quality of diesel fuel and how that affects
fuel economy in these smaller engines. On a good week with higher centane or less water content in the fuel,
the van averages 5.2 l/100 km in mixed driving but with a dodgey load, that goes up to 5.7 or 5.8 in spite of
my best efforts to light pedal...Since changing from older D22 Navaras, my employer has halved his fuel bills.
I'm actually hoping that Holden tries a couple of products with smaller diesels to push the envelope and change
the way buyers feel about small diesels in cars and SUVs. The good fuel economy is there for the taking.
Water content shouldn't be a running issue - they have water traps built into their fuel filters - but will need emptying more frequently is the fuel's water content is high.
