Release available, so come on - to try this high-oil (Audi TT). Kann delude myself, but it seemed to me directly after the oil change before as if everything run quieter and quieter. But what bothers me and that I will again investigate: I have weighed the oil and came out 4.5 kg! Filling confirmed this, because I needed the full 5 liters, although my car requires just 4.5 liters according to the manufacturer. Strange? Why the oil with packaging weighs very precisely 4.5 KG ... similar is already happened to me with fireplace-Ethanol: bought 15 liters, and according to balance missing 2 liters per canister (!). I do not know if there are similar to USB storage devices, etc. allowed tolerances. According window 5 liter canister were in, but above the "shell" is so much smaller ...
