After four years and a good 45 tkm I took some old oil with me after the regular oil change. The vehicle was maintained according to the specifications of JLR. There were no delays. The car is also completely inconspicuous, the hot, everything works well. I now got a “red” in the analysis on the topic “wear”, the rest was in the middle range, as well as the overall result. The wear element content indicates however an irregular wear in the system. r is worried. Can I change something with a half-year oil change (approx. all 5tkm) or is the engine going up soon? Especially far above the limit was the proportion of iron.
