Hello, I drive a FoFi 1.1 l. I have to pour some oil sometimes, because my car has a certain amount of oil consumption. I have to say that I demand a lot from the engine (120 tkm run). In other words, I drive quite high speeds and the mountain up and down mountain. And on the highway, I always drive max. speed. What the engine gives just. My consumption of oil is on average at the difference of min to max (I think that’s a half liter, or?) on the pier at 1000 km. I drive with partly synthetic 5W40 oil. Is this perhaps the wrong oil? Thanks already for the answers in the pre-panissimo
