[QUOTE="cidsamuth, post: 11786735, member: 110091"] This has been discussed much on other forums. To summarize what we know so far: 1. In addition to the GT500s and Boss Mustangs, the 2013 Track Pack came with an oil cap stating 5w-50 was required. However, the manual still said 5w-20. In response, Ford has issued a supplement to the owner's manual stating the Track Pack GT needs 5w-50. 2. According to a Ford rep on ALLMUSTANGFORUMS, there is no mechanical difference between the 2013 GT and the 2013 GT Track Pack. The difference is only the "expected use" of the motor, i.e. for track use. 3. This would imply that 5w-50 could be used in the regular 2013 despite what the owner's manual said. When asked whether that was true, the Ford rep did not directly answer. Further, even if the regular 2013 GT could use 5w-50, she did not comment on whether this logic could be applied to the 2011-2012 GTs or whether the oil squirters precluded it. Bottom line, at least for the 2013s, it would seem the 5w-20 might be "required" only for CAFE, as many have suspected. However, it could still be argued there is a mechanical reason for the 5w-20 on the 2011 and 2012 models. [/QUOTE]
