Probably a smart move. I changed factory oil at 1k, second oil change sample went out for a UOA 3k miles later and there were a good amount of wear metals per Blackstone (aluminum and iron were both slightly high, copper was very high). They said it was consistent with break in characteristics of other 2.0ecoboost motors but I'm glad I got some fresh oil in there after 3k. I will continue 3k changes especially considering I also had 1% fuel dilution and under threshold flash point and viscosity ratings after 3k miles. This is on Castrol Edge full synthetic 5W-30.
This is what I did on mine. I followed the owners manual 1,000 mile break in period instructions then had the oil changed. I haven't gotten to 5K miles yet but plan on having it changed when it does then every 5,000 miles after that.
I need to get to the post office to mail mine out. I put Motul 8100 in but I will be switching to Pennzoil Platinum Euro 5W40 next oil change.
I definitely recommend spending the 30 or so dollars on a used oil analysis, this is my third 2.0 ecoboost motor and in about 250k miles combined on the previous two I'd see significant fuel dilution and as a result lower flashpoint and viscosity, even on 3k changes. I'm not saying that is universal since everyone has different driving habits and will use different fuels and oils and filters etc but for me and my driving habits I think 5k intervals would have been pushing it since even on this last oil change on my maverick at 3k, flashpoint was down to 260 degrees and SUS and cSt viscosities were both below standard. These motors really really like clean, fresh oil. Flashpoint is my biggest concern considering cylinder temps on these motors can approach 400degrees so at that point with a degraded flashpoint you're burning oil in the rings and clogging them with carbon, something you really won't be able to mitigate as time goes on. Of course these are just my opinions and everyone is free to do what they want but coming up with an arbitrary number for intervals can be dangerous with an ecoboost motor instead of finding out exactly what condition the oil is in after the interval you'd like go with a good used oil analysis.
LOVE MY MAVERICK!!!
Good to know as Ive never owned an ecoboost, I was thinking about adding a catch can, do you think that would mitigate the fuel in the oil situation?
I don't think so, I ran a catch can on my Focus ST and still had the issue mostly because fuel gets atomized into a fine mist by the very high pressure injectors directly into the cylinders and then with all the cylinder pressure of a 9.3:1 (I think) compression ratio along with 15-20psi of boost there's inevitably blow by past the piston rings so this atomized fuel goes right into the crank case and mixes with your oil. I like the idea of a catch can I just haven't personally been too impressed with the products currently on the market.
Yea my other truck has the new ford 7.3 gas burner with a pushrod v8 and port injection, about as old school as you can get these days so I dont worry about it much, will have to keep my eye on this little turbo, sure is fun to drive though, other than the noisy clatter of the direct injection.
