We just got a new fusion in our fleet (first time we were willing to go with a Ford Sedan in about 12 years). Reading/finding the specs in the owners manual was awkward. I forget how many engine options they had (from the 1.5T and up). The Turbos were 5w30 and the NA were 5w20.
So Ford has not switched back at all...

Unfortunately, it'll be portrayed on here as Ford going back to 5w-30 because of towing requirements in Death Valley and "protection" versus what it actually is...using 10w-60 doesn't give me additional "protection", it just makes my car run like [censored]. With the advent of DI, "protection" can be thought of as a multi-edged sword where the oil grade recommendation and other specs are related to the DI component and not free reign to run 20w-50 in it because "Ford got it wrong". Then again, this is the only board I'm aware of where people who buy DI cars are called "early adopters"...that's with currently over 40% of the new car market being DI vehicles and DI cars being sold in numbers for the last decade...that's beyond hilarious.
When DI first came out in gas engines people who bought cars with DI were early adopters. In fact anyone who buys the first or second year of any new technology are considered early adopters, and it has nothing to do with DI. It took a few years for DI to get sorted out, and it's still a work in progress. I bet some of the early adopters who got burnt wished they would have waited, or bought something with fuel injection instead.
