Toyota mówi: „to norma”… A my sprawdzamy olej z Lexusa 2.5 #315

In this episode, we take a closer look at a hybrid setup that’s rarely tested on the R2D channel — the Lexus NX 350h with a 2.5L A25A-FXS engine. With two carefully prepared oil samples — one fresh and one used — we explore how this unit handles 0W16 oil in everyday use. 💡 What’s the story? Grzegorz, the episode's contributor, previously owned a Corolla TS and noted a strong fuel smell in the oil. Now he’s switched to a more powerful hybrid and wants to find out if the fuel dilution issue persists. The oil tested here is Toyota 0W16, drained after 5,600 km of mixed use — mainly short city commutes, plus occasional long highway runs. 📦 What's in the package? – Sample 1: Fresh Toyota 0W16 – Sample 2: Used Toyota 0W16 after ~5,600 km ⚙️ Key test results you'll see in the video: – 20% drop in viscosity at 40°C and 17% at 100°C – FTIR indicates fuel-related peaks and some contamination, but most parameters remain within safe limits – Spot test (MCU + R2D) confirms high oil quality overall, but also shows a subtle turquoise ring — typical for fuel traces – Oil quality index: 84%, with signs that earlier oil change could be beneficial 🔬 Why it matters: Even in new hybrid engines, city driving and frequent restarts can lead to fuel dilution and faster oil degradation — especially with ultra-low-viscosity oils like 0W16. This case highlights the importance of monitoring oil condition, even in modern hybrid setups. 📊 Bonus: We compare this oil to other 0W16 samples tested on the channel — including Motul and Toyota oils from episodes #26, #71, and more. 📧 Want to test your oil in our lab?
