Why 0W-20 is Critical for This Engine
The 2.4L Turbo (T24A-FTS) engine in the Grand Highlander operates under high pressure and temperature conditions. Low-viscosity 0W-20 oil is essential for ensuring rapid lubrication of the turbocharger bearings during cold starts and maintaining a strong protective film under heavy load.
Using incorrect oil will:
- ❌ Increase turbocharger wear due to delayed lubrication
- ❌ Cause deposits to form on critical engine components (sludge)
- ❌ Negatively affect the variable valve timing system response
