Might want to rethink that.Royal Purple 5w30.
I'm good.Might want to rethink that.
I'm also sticking with Motorcraft full synthetic.All of the for techs I’ve talked too that have lots of experience replacing cam phasers recommend explicitly sticking to motorcraft full synthetic. So that’s what I’ll be using.
All of the race engine builders that I’ve talked to say that Mobil 1 is the worst!
I'm leaning towards the Pennzoil Ultra Platinum 5W-30 as well given the cost/performance. Have just about 900 miles on my '25 RR now and plan to do the first change before 1500 miles. Just got my UPR catch can delivered as well so great timing to do both at first oil change.Pennz ultra platinum for me, Ford spec is on the bottle.
I used Motorcraft at the first change then SuperTech from Walmart for the two subsequent changes. I really like it and have ran it in everything for many years.
Did my first at 1000, going every 5000 from here on out...I'm leaning towards the Pennzoil Ultra Platinum 5W-30 as well given the cost/performance.

Probably a good idea. My goal is to get it done this weekend so will be somewhere between 1000 and 1200 miles. I will do changes every 5k miles as well.Did my first at 1000, going every 5000 from here on out...
