why is my Tesla Model S Plaid/Refresh (2021-present) using so much oil

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface.
• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to prevent electrical issues.

2. Inspect and Repair Oil Leaks

• Tools Required: Socket set, torque wrench, gasket scraper
• Inspect the oil pan, valve covers, and gaskets for leaks.
• If leaks are found:
  1. Remove the affected component (e.g., oil pan or valve cover).
  2. Clean the gasket surfaces using a gasket scraper.
  3. Replace gaskets or seals as necessary.
  4. Reinstall the component and torque to manufacturer specifications.

3. Investigate Engine Components (If applicable)

• Tools Required: Compression tester, leak-down tester
• Perform a compression test to check for internal engine issues.
• If low compression is detected, conduct a leak-down test to identify the source of the problem.
• Based on findings, consider further disassembly of the engine components or replacing faulty parts (e.g., piston rings).

4. Replace Oil and Filter

• Tools Required: Oil filter wrench, oil catch pan, funnel
• Drain the old oil using an oil catch pan.
• Replace the oil filter with a new one.
• Refill the engine with the manufacturer-recommended oil type and quantity.
