Our family vehicle is a 2015 Ford Transit Connect (Wagon, passenger version) with a 2.5 liter NA engine. It currently has 95k miles. During the last oil change I noticed that it had a little oil on the bottom of the engine where it meets the transmission bell housing so I suspect it has developed a minor leak in the rear main seal. I have been using basic M1 5w-20 and following the IOLM for OCI since we bought it (used with 20k miles). I am looking for a suggestion on what oil I might switch to so that the leak is minimized.
I have researched this engine and it is a Ford Duratec 25/Mazda L5-VE. This same engine was used in the Mazda 6 until 2012 and for that application could use a 5w-30.
I want to stay with a full synthetic and would like to continue following the IOLM.
To minimize the oil leak, would I be better off switching to 5w-30 instead of the Ford recommended 5w-20? Or should I try a "high mileage" oil instead?
If you recommend a "high mileage" oil, what brand should I go with?
Thanks!
