Hello dear community, after the SuFu has not delivered me a suitable result my question: For a long time I have been thinking about the near/after heavy motorway rides the oil control light burns (after a short stop) Yesterday as well, today I checked the oil level with cold engine and it was ok. Otherwise I refilled it quickly. I know that the good oil needs (despite changing oil traps). But why does the lamp burn even though there is enough oil on it? I change oil regularly (10 W40) with filter (with check valve from the accessories; no original)
