@mechanics.life4: BLUE smoke and WHITE vapor can tell very different stories. Can you recognize all five? ⚫ Black → Possible fuel/air imbalance 🔵 Blue → Often burning oil ⚪ Thick white → Possible coolant leak; unburned fuel is also possible in diesels 🩶 Gray → Possible oil burning or PCV trouble 🌬️ Thin white vapor → Often cold-start condensation 👀 Compare THICK WHITE SMOKE with THIN WHITE VAPOR before you scroll. That difference matters. Smoke color alone can’t identify a failed part. If it persists after warm-up, get it checked. Which color surprised you most—and why? 👇 Save this for your next car-care conversation.
