well i just filled tank to the top. i need to point out that i always fill my tank to the top on Vortex ,so the gauge stays @ full till 250k or there abouts in the city, it stays at full to about 300k in country. & if i drive for economy ( this does not mean like an old .......
) if i drive for economy i can go around 350k before gauge goes off the full mark. then have found its roughly 250k in the country between the marks on the tank gauge, but if i pay attention and try for economy can increase that margine. i just filled up and as i predicted worked out @ 4.40L/100K this is first time i have got to 4.4 per 100k useing vortex diesel, the last time i averaged 4.4 was with mobile. but on the trip down the coast to Melb i went 1,030k and could only get 44L in to fill the tank so that trip slightly better on Vortex but had to fill up on BP down there.
For those that want to fill the tank right up, i point the spout upwards and toward the side of the filler tube, this causes the diesel to spin in a fast counter clockwise dirrection it makes it easy to fill uip and does not spit. but useing foaming diesel could be different but can't see why, just it takes time for foaming to go down.
a side note, i did not use the air conditioning.
