High oil consumption at Swift

Good evening together! I have a problem with my Swift Bj. 10/93 which makes me a bit stutzig. Alllsooo: I posted about 2 months ago because of oil in the LuFi box. Was shortly after the purchase of the vehicle. This has now become normal. I then made an oil change and then was no longer exceptionally much in the box. Cartridge remained unpolluted. And a little oil in the LuFi box seems to be normal as I had to say. Oil level was na Now I have found that he needs quite a lot of oil. About 3000 km a little more than a litre. Is that normal? OK, maybe I think about old BMWs or something. But with a 1l three-cylinder carburetor suzi…. There are no power inlets, no oil in the cooling water, no steam out at the back. No increased consumption (constant 6,5l). Cooling hoses are also not hard at the engine run. Is there something going on or is there already something in the bucket? I really don’t care about the ÖL. This is portable. I’m only grumbled at a consequential damage to the engine. Thank you very much for your help in advance Chris
