Yes it is.

Welcome!

Hi Imberbe

Thanks for the quick reply. Do you know at witch camps?

I am also unaware of any low sulphur diesel availability inside the park. I go to the Sasol in Malelane to fill up (or Komatipoort if in that area).

You will only find the Total brand inside the park with 500ppm diesel.

Seeing there seems to be conflicting info as to the availability of 50ppm diesel I would like to point out that utilising 500ppm diesel in modern common rail diesel engines for limited periods will not adversely affect the motor or diesel injectors in the short term provided the diesel is of a good quality - and that is assuming that the KNP suppliers are reliable .
The use of 50ppm diesel has for a number of years been recommended by all manufacturers of common rail diesel engines as it is thought that it promotes longer engine life , and I do not recall that 50ppm was available in KNP a year or 2 ago - in fact it is not available in most of the northern Cape province and most rural areas and small towns in SA - thus can be deduced that manufacturers would certainly not market their cars in these areas had the occasional use of 500ppm been detrimental .

There is a Sasol garage which i use just outside Komatipoort (nearest camp is Crocodile Bridge) on the N4 that has 50ppm diesel.

For me this is good news! Many manufacturers nowadays specify 50 ppm Diesel as the only fuel to be used in their newer vehicles.

I find this very interesting: my car (Audi A6 3.0 TDi) consumes just about the the same quanitities of fuel in Kruger as in city traffic - about 10l/100km (10km/liter), while on the open road it goes as low as 6l/100km (16.4km/liter). It is thus easily 40% heavier on fuel in Kruger than on the open road.

I guess it has to do with a heavy vehicle stopping and pulling away? And does it mean that a vehicle with a smaller engine or less torque finds it more difficult to cruise on the open road?

It will be interesting to calculate the actual costs in terms of fuel used by the two vehicles mentioned: with 55 liters I travel the 450 km to KNP from home and have enough left to do another 250-300 km in Kruger. How much will the Aveo use to travel 450 to KNP and then do a day's travel in the park?

Seems driving habits & patterns decide consumption . It may be that in the abovementioned case in the KNP the Aveo drives at a more constant speed than the Audi , if more stop starting is done consumption may be far higher .
I experience the same pattern as Dupacc , though if I drive a diesel at a constant speed (such as in the Kgalagadi when commuting between the camps & entrance gate at a speed that irons out corrugations) , the consumption is very low . I think turbodiesel engines are generally not as economical as petrol engines in the stop / go mode as the turbo requires some time to spool up and become effective , the management system injects extra diesel to overcome this - thus the puff of smoke often seen om pulling away .
The Audi turbodiesel engine is generally far more economical on the open road at cruising speeds than a the Aveo with petrol engine would be .
