Hi all I write here so please help me with a question: I currently own a 2013 Mustang 5.0 with approximately 46,000 miles. I must change engine oil, and according to the manual this must be 5w20 and comply with the WSS-M2C945 standard. Now, that you swap with the above, in my country I have found only Motorcraft synthetic blend, and full synthetic; Mobil 1 full synthetic. I currently use Redline 5w20, which I am not sure meets the standard indicated by Ford. If indicated, which option will be the most appropriate? Thank you!!
