I don't know why Ford don't make stricter standards of what oil goes in there Eco-Boost. But I agree with earlier postings, go with a Dexos1 Gen2 oil, and make sure its a full synthetic. Most Dexos1 Gen2 are Full Synthetic, but there are a few semi-synthetics that do pass for that. Its not required by Ford, but I would do it. To keep the warranty intact, make sure also passes the approiate Ford specs. which most Dexos1 Gen2 oils usually also has that.
