Introduction

This video debunks the common claim that some car fluids last a vehicle's lifetime. The Car Wizard uses a 2015 Lexus ES300h with 187,000 miles to demonstrate that transmission fluid, despite manufacturer claims, requires servicing.

Key Takeaways

• Lifetime Fluids are a Lie: Many manufacturers falsely claim certain fluids (like transmission fluid) are "lifetime" fluids, needing no service. This is untrue; fluids degrade and require changes, typically around 100,000 miles.
• Transmission Fluid Degradation: The video shows a stark visual comparison of new and used transmission fluid. The used fluid is black and contains significant debris, indicating wear and tear.
• Dealers Avoid Service: Dealers often refuse transmission service, even when requested by customers, upholding the "lifetime fluid" myth. This is to avoid costly repairs and maintenance.
• Independent Shops Recommended: The video recommends using independent repair shops for transmission servicing as they are more likely to perform necessary maintenance.
• Consequences of Neglect: Ignoring transmission fluid changes can lead to premature transmission failure and costly repairs.
