75,000km with NO oil change? 😭 This engine should have given up at 20k. The fact that this Corolla still ran is a testimony that Toyota builds engines like Nokia 3310. But looking at that picture, that is not oil again. That is SLUDGE. Black, thick, like akara oil that has been used for 3 years. This is what happens inside when you don't change oil: 1. Oil turns to sludge — it can't flow, can't cool, can't protect 2. Oil pump gets blocked — engine starves 3. Timing chain wears out — you go hear "krr krr" on cold start 4. Engine overheats from inside — even if your temperature gauge looks normal 5. One day, engine just knocks. No warning. ₦1.2M - ₦1.8M for a new 2ZR engine in Lagos. And people will say "Toyota is reliable". Yes, but even Toyota needs oil. Rule in Nigeria, because of heat + traffic + bad fuel: - Full Synthetic Oil: Change every 8,000km - 10,000km MAX - Semi-Synthetic: Every 5,000km - If you drive in Lagos traffic every day: Do 5,000km, don't wait for 10k "But my mechanic said I can do 15,000km" Your mechanic is lying to you to sell you an engine later. Check your oil today: Pull the dipstick. If the oil is black like this picture, thick, and smells burnt, you are already late. Don't wait till your engine looks like this.
