I have watching videos of certified ford mechanics voicing their opinions of Ecoboost engines. Nearly all have stated change your oil more frequently than the manual states. They stated engines get varnish build-up on the engine internals. Because of synthetic oil extended recommendations, & because they are turbo-charged engines. "Oil is Oil" the mechanics said. That said oil is full of contaminants being recirculated through out your engine, for a longer period of time. So just get rid of it. Your engine will like you for it. They were talking about ecoboost 3.5 engines with 200k miles or more they were rebuilding. OIL is the key. Plus being aware the cam chains and guides on the v-6 ecoboost. I haven't looked yet about the 2.0 ecoboost. I personally have never let my engine oil change go longer than 3 thousand miles. Your thoughts, experience, Ecoboost owners?

Regardless of my car, I always do 3k miles. Some people say you can wait 5k or even 7k miles with synthetic. But my father always told me it's 3k no matter what and worst case, you are running cleaner oil which is NEVER gonna hurt your engine. So take that for what you will.

I do right around 5k. Even then the oil looks pretty clean. I changed my mother in laws oil at 3k because it had been over a year and that stuff looked brand new. She is retired. At the end of the day more oil changes are never bad. I personally go through 5k miles every couple months so to avoid monthly oil changes 5k has been my go to. I was having trouble at the shop with reliable oil changes so I started doing them at home late last year. Pretty fun to do. Just need a portable hydraulic jack for ease of work. I'll probably add one at some point.

LAFFING>>>>"Pretty fun to do" I used to do ALL my own oil changes. Not anymore. I have the dealership do it. Let them be responsible, plus the paper trail. I might as well lock the hood as I don't even look under there anymore. I do my 1970 Montego ;-)

I have an app for paper trail. It's more of a therapeutic thing an easily completable project. I was using a local shop, they did ok but got a new guy who made a couple of mistakes. I got tired of it so just got the stuff to take care of it. 30 minutes and I actually check the condition of my vehicles personally so not a total waste. They also charged my wife an absurd amount on an oil change once, I was pretty mad.

A high quality Synthetic oil Sb good for 10k miles - that is the interval Volvo recommends for their 2.0 turbo - supercharged T6 variant

Agreed. Audi is as well on their 2.0. My sprinter was 20k, but there was a lot of oil in that engine. I think 3k is a waste of money.

not only a waste of money, but wasteful for the earth's resources - having to recycle all of that hardly used oil, etc.

i only change the oil in my 08 canyon every year now. i drive maybe 11-13k miles per year. I get the synthetic rated for 15k miles and ditto the filter. I think it's actually about 2X as expensive as regular synthetic/filter, so really I'm just saving one change a year. I couldn't see myself changed it more then every 6k miles, so it's basically the difference between 1x and 2x changes per year. I've been doing this for 4-5 years now I think, no issues, it has around 135k miles so far, had 35k when i bough it in 2013, no major repairs (changed a thermostat and doo dad here and there, nothing over $100 or so)

I highly doubt changing it 3k miles is anything but superfluous, but If it makes you feel better, cant hurt anything (well technically you could, more chances at stripping out the oil nut or forgetting it, etc, but anyway)

If I got one of these turbos since it's brought up here I'd probably follow the manual on oil change interval. At least the first few years for sure before it got old, beat up, and you dont care anymore :)
