Im looking to step up the quality of oil in my ecoboost to help prevent the timing chain issues like some are having. Currently have 37K on the clock, still under powertrain warranty but my truck does not see the dealer much. I'm debating on running GC 0w-30 in it since its a high HTHS oil but is a pain to get around here except for a trip to AAP 30 minutes away. I recently found DELO 5w30 that is SN rated and has a HTHS of 3.5.

Since I dont go to the dealer much anyway which one would you run? I could skip either and go to M1 0w-40 but would like to stay with a heavy 30 if possible. The DELO would be $5.50/qt, GC 5.50qt, M1 $5qt approximately, so not much price difference.
