Because only Shell has this Premium diesel, and Shell always ask the highest price, I refuse to use Shell.
But I'm now 76, from my 26 th year I drive diesel cars, in the begin i drove average about 100.000 km/year, now les, but: always use regular diesel, and have Never, again NEVER clogging fuel injectors.
Oh, by the way, you live in Europe and have the Euro, about Shell, when the euro made its appearance, Shell was afraid they would lose money, so before you had even filled up a drop, there was already 2 eurocents on the pumpmeter.
Shell was the only company to do so.
