When ordering the oil for an oil change in one of the well-known shops, I ask myself, we usually dispose of the waste oil. The seller is obliged to take back the oil, but in contrast to the new one, waste oil is classified as hazardous goods and therefore can only be shipped in special containers (the product packaging is not enough). The exorbitant shipping costs would then completely eat up the cost advantage. Information about this (except that the dealer has to withdraw the oil and a reference to waste oil disposal companies). Is there besides burying in the forest or parking on a motorway parking place also an easily feasible legal possibility to get rid of the oil again. If I look at the indicated waste oil disposal companies, then I can usually specify the quantity (a little excessive) in tons and ask for an offer for the collection. It is clear to me that when calculating the price of the waste oil disposal companies Shipping prices are taken into account that practically nobody uses the disposal, but more than 1-2€ can not really make up for this. Of course, I’m not necessarily looking for a free solution.
