Although many are complaining that a thread is opened over it, I hope to find an answer anyway. The oil dilution in the current diesel engines, favored by diesel particle filter regeneration, is no longer a mystery. Especially the contained RME evaporates almost hardly out of the oil again. Poor lubrication effect is the result. As far as so good. Aral Ultimate Diesel contains no RME according to various sources, but now over a bad lubricating effect But how can there be a bad to harmful lubrication effect if fuels have to comply with DIN standards?! According to Aral this fuel even surpasses it?! If the fuel would endanger the injection pump, why is it nowhere reserved?! Please spare yourself comments like “they deserve it if something goes wrong “. If something breaks in the warranty period, then they have to pay for it and they refuse to do so, then they would also noc h lose a whole momentum customers. It is also noted that the vehicle in cold condition is not too overloaded. Funny if they deserve it. My vehicle is a Golf 7 2.0tdi Common Rail. I would be very grateful for informational answers about the subject of lubrication effect of Aral Ultimate.
