Hello I found today that now here in Munich by Aral 2 new fuels are offered, namely Ultimate 100 and Ultimate Diesel. The diesel cost in comparison 9 cents more than the normal diesel is already happy compared to the diesel at the free petrol station true again 6 cents cheaper than the from the brand filling station That can hardly save 15Cent per liter extra price. So Aral has now equalized with Shell or. according to the info on the web of Aral is of course their S prit the best on the market. I would now be interested in what you hold of the Themer and defend everything ready to refuel the fuel even in the long term. I personally would only do this if it proved that 1 of the fuel consumption is reduced 2 the wear on the engine is noticeably lower 3 if you then calculate everything together about as much as the normal diesel. So then until soon Michael N.
