Something I'm noticing is that any "German" parts supplier that carries LIQUI MOLY products lists LM22090 for our car.

My main concern with LIQUI MOLY is that NOBODY, absolutely NOBODY used the LIQUI MOLY (12") extension-tube to get the fluid into anything. They used either a hand-pump or gravity and a funnel. So if I go the LM22090 route then a trip to my local Harbor Freight Tools will be in order. https://www.harborfreight.com/gear-o...ump-61746.html
