What's everyone's opinion on using Kendall GT1 Max 5w30 in a 2017 Ford Fiesta ST ecoboost with less than 30k miles? I switched my Crown Victoria over to Kendall GT1 max 10w30 and I'm liking it quite a bit. Thought I would try the 5w30 in my Fiesta. Right now it has Castrol Edge EP 5w30 in it. I tried Mobil 1 ESP which had a nice high hths, but it didn't carry any of the Ford requirements/specs like the Kendall and Castrol have. Or is that something I should even be worry about?
Thanks!!
