On the 2020-2025 BMW M8 S63TU4, the M8 S63TU4 4.4L twin-turbo V8 can consume oil at rates exceeding 1 quart per 1,500 miles, particularly when driven spiritedly. The issue is related to the valve stem seals and piston ring design that allows oil past the rings under high boost and high RPM conditions. BMW considers up to 1 quart per 1,500 miles "normal."

Common Symptoms

  • Oil level drops between changes
  • Blue smoke on startup
  • Blue smoke under hard acceleration
  • Oil consumption above 1qt/1500mi
  • Oil smell from exhaust
  • Low oil level warning
  • Fouled spark plugs

How to Fix

Monitor oil level regularly using iDrive oil level check. For excessive consumption beyond BMW's threshold, valve stem seal replacement may be warranted under warranty. Updated piston rings are available for severe cases. Always keep oil topped up between changes.

Typical repair cost:$200 - $5,000

On the 2020-2025 BMW M8, the M8 adaptive M suspension dampers can develop leaks from the electronically controlled valving, causing a loss of damping force on the affected corner. The complex internal valving and seals are stressed by the M8's weight and performance demands, leading to premature wear compared to conventional dampers.

Common Symptoms

  • Bouncy or floaty ride on one corner
  • Suspension warning light
  • Visible oil leak on damper body
  • Uneven handling feel
  • Clunking over bumps
  • Body roll increase on one side
  • Damper fault in iDrive

How to Fix

Replace the leaking damper(s). BMW adaptive dampers must be replaced as complete units — they cannot be rebuilt. After replacement, a suspension calibration via ISTA is required to integrate the new damper into the adaptive system. Replacing in pairs (front or rear axle) is recommended.

Typical repair cost:$1,200 - $3,500
