Zmiana parametrów oleju po dodaniu płukanki długodystansowej, Daewoo, Matiz, 10W40 #284

How does a semi-synthetic oil behave in a small city engine? In this episode, we test oil from a 2003 Daewoo Matiz (0.8L / 51 hp), driven mostly on short urban trips. The oil in question: Millers Trident Professional 10W40, used over 3250 km, then flushed with a long-term additive and driven an extra 1600 km. The test includes: 🔹 Fresh oil sample 🔹 Used oil after 3250 km 🔹 Used oil + flush after 4850 km total We measure viscosity, analyze the FTIR spectrum, and assess oxidation, soot, and possible fuel traces. The chromatography blot test shows a clear cleaning effect from the flush, and viscosity drop remains within expected limits. Key questions explored: – Is this oil still suitable for older, low-power petrol engines? – How does city driving affect oil aging in such cars? – Can long-term flushing improve oil lifespan? 📩 Want to join a similar test?
