Hi all,

I am new to the site. I've had 2 Mustangs but just picked up a 16 EcoBoost last week and I have a question about the oil. I have heard mixed reviews as to when the first oil change should be on a brand new car. The break-in period is 1000 miles, and Ford doesn't specify in the owner manual, it just says change it every 7,500. Should the oil be changed before that, as there could be gunk circulating in the oil due to burn off from the brand new engine? Or with these new cars do they want you to break it in for the full 1000+ with the original oil?

Thanks!

Ok 3,000? I just hit 1,000 so I'll keep that in mind. I am going to switch to full synthetic as well, you mind if I ask what you used? I have always used Pennzoil's line of full synthetics, do you have another preference?

I did my first oil change in my '15 after the first 3K I put on it, I bought it with 20K, at 23K I changed it, then every 5K after that I've been changing it, since it is a synthetic blend, it can go 5K, I wouldn't recommend 7.5K

Why not just go by the oil life indicator? My Z06 get's its oil changed once a year, or when the oil life monitor says it's time to change it whichever comes first. The wife's Ecoboost goes almost 10K before its oil gets changed. Today's oils have plenty of additives in them and the old "change it every 3000 miles" is no longer valid. Changing the oil before its time is a huge waste of money and resources. I send samples of my oil to Blackstone labs and have it analyzed on a regular basis. The lab analysis, at least for my Vette, shows I could go as much as 15K miles between changes with no detrimental effects.

In case anyone in here is truly serious about extending their oil change intervals, or may just be curious about how their engine is holding up based on their used oil. I've posted one of my Blackstone Lab reports you get when you have your oil analyzed. The report below was for my '03 Cobra. If you look at the columns you'll see the results from 2 separate tests. One done at 13,375 miles and 16,920 miles. If anyone is interested I can dig up the report for the Ecoboost and post that too.
