Question for ecoboost owners, and anyone else that wants to chime in. I'm reading where most ecoboost owners are doing their first oil change at 1000-2000 miles and then every 5000 after that. The owners manual basically says depending on your usage and environment the truck is used in, you can go 7500 on the FIRST oil change and then every one after that or whatever the oil life monitor calls for. I did see a video on YouTube of a guy with an ecoboost doing an oil change at 2000 miles and his oil was black. I mean diesel oil black. Should I just do the first one at 5000 miles and every 5000 after that or do one at 1000 and then go from there?
This question should get you a lot of opinions. My 2015 had 10086 miles on it when I bought it. It was a demo that had never been registered. My service guy at the dealership pulled it up on their computer and it showed to have had an oil change at 7200 miles. I had the oil & filter changed at 13546 miles, and right now it has 18322 miles on it. So first oil change at 7200, second at 13546 or 6246 miles, and now it's been 4776 miles since the last oil & filter change. I checked the oil yesterday (something I rarely do anymore) and it might have been as much as half a quart below full. The oil life monitor showed 53%. So . . . apparently Ford thinks it can go 10000 between changes.
Now maybe they're right. But some of us are old enough to remember when cars didn't have an oil filter, you changed oil every 1000 miles and if you didn't have to add more than one quart between changes, you had a really fine engine. But they added an oil filter and first thing you know, cars were going 3000 miles between changes, then 5000, then 7500, and now up to 10000.
Now there can be no doubt that the Ford engineers know a great deal more than I, but I reckon I'm just too old to go by that oil life monitor (I'm not sure it's based on anything other than mileage), so I reckon I'll keep changing oil & filter at 5,000 miles, and, yep, it's a synthetic oil, or as Motorcraft labels it, a "Synthetic Blend".
