What oil does a 2005 Ford GT take?

About 8.5 quarts of synthetic 5W-20 oil, meeting Ford's WSS-M2C930-A specification.


The 2005 Ford GT uses a high-performance version of Ford's modular V8 engine, and choosing the correct oil is essential for peak performance and long-term reliability. The official guidance specifies a particular viscosity and a certified specification, and owners should always verify the latest requirements in the owner's manual or with a Ford dealer. The following sections summarize the established guidance and practical considerations for this iconic supercar.


Oil type and capacity


Key specifications to follow when purchasing oil and planning oil changes:



  • Viscosity: 5W-20 synthetic oil

  • Capacity: Approximately 8.5 quarts (about 8.0–9.0 quarts, including the oil filter)

  • Specifications: Meets Ford WSS-M2C930-A; API SN or newer; approved brands include products from Mobil 1, Castrol, and others that explicitly meet the Ford spec


Using oil that meets these specifications helps ensure proper lubrication, engine protection, and performance in the Ford GT's high‑RPM operation.


Brand and maintenance considerations


Practical tips for selecting the right oil and maintaining the car:



  • Always verify the current specification against the owner's manual or a Ford dealership, as revisions can occur over model years.

  • Choose a reputable brand that explicitly states compliance with WSS-M2C930-A (for example, Mobil 1 5W-20 or Castrol EDGE 5W-20, among others).

  • Replace the oil filter at every change and ensure the total oil is filled to the specified capacity; do not underfill or overfill.


Following these practices helps preserve engine health and performance under the Ford GT's demanding driving conditions.

What kind of oil does a 2005 Legacy GT take?


For a 2005 Subaru Legacy GT, the recommended oil type is 5W-30 synthetic oil. It is crucial to use a high-quality synthetic oil to ensure proper lubrication and protection for the turbocharger, as conventional oils can degrade faster under the high temperatures from the turbo. 

  • Oil type: 5W-30 synthetic oil is preferred for all temperatures. 
  • Why synthetic: Synthetic oil provides better thermal stability and protects the turbo from wear caused by high heat. 
  • Oil change interval: Regular oil changes every 3,000 miles are recommended to prevent sludge buildup. 
  • Alternatives: Some users have reported success with other high-quality oils like Motul 5W-40 or Shell Rotella T6 5W-40, but sticking to 5W-30 synthetic is the standard recommendation.
