Why 0W-20 Oil and Direct Injection Are Killing Modern Engines | Scotty Kilmer Warned

Описание: ⚠️ Modern engines are failing earlier than ever — and it’s not by accident.

If your car uses 0W-20 oil and gasoline direct injection (GDI), this video explains why many mechanics are seeing carbon buildup, misfires, oil consumption, and costly repairs at shockingly low mileage.

This isn’t fear-mongering. It’s real-world data, teardown evidence, and field experience from working on hundreds of GDI engines.

In this deep dive, I break down:

Why GDI engines suffer intake valve carbon buildup

How 0W-20 oil accelerates deposit formation

Why older port-injection engines didn’t have this problem

Real mileage examples of carbon damage (30k, 60k, 100k+)

The role of the PCV system and oil vapor

Why automakers quietly moved to dual injection systems

How much carbon cleaning really costs (and how often it’s needed)

What actually helps slow the damage — and what doesn’t

🔬 You’ll also learn how to protect your engine, including:

Proper oil change intervals for GDI engines

Why extended oil change intervals are risky

The truth about fuel additives and intake cleaners

When walnut blasting is unavoidable

Whether oil catch cans are worth it

Driving habits that make carbon buildup worse (or better)

🚗 This video is especially important if you own:
Toyota • Honda • Ford • GM • Hyundai • Kia • VW • BMW • Mazda
—or any vehicle with direct injection and 0W-20 oil

📉 Carbon buildup in GDI engines isn’t a defect — it’s an inherent design trade-off driven by fuel economy and emissions regulations. Understanding that trade-off is the key to avoiding surprise repair bills.
