I have a '12 Focus too. Planning to get a used oil analysis? I'm interested to see how much fuel might be in the factory fill oil.
For a newbie, please define FAR and MIR. They're not on the official BITOG acronym definition page.
Free after rebate and mail in rebate. The factory fill has already been dumped and filled with motorcraft again. Car has a total of 2500 miles on it right now. I will get a used oil analysis after the next OCI or 2, not worth a used oil analysis on a engine breaking in as you can't establish a wear pattern yet. But eventually, yes, I will be doing a used oil analysis.
Ah-ha, thanks. Yeah I understand about the wear, I was just hoping to get an early indication of fuel dilution and oil life remaining (viscosity, TBN) with this DI engine after 7,500 miles or so. I changed the factory fill at 1,500 miles and plan to do the next change at 9,000 miles and will probably get a used oil analysis done at that point. Unless someone else's used oil analysis shows that this new engine dumps a lot of fuel in the oil in which case I'll change it sooner. Ford recommended OCI is 10,000 miles.
I changed with MC at 1500 miles as well.
Personally, I'd dump it before that for a couple reasons.
1. There is still a lot of break in metals floating around in the oil.
2. I haven't seen a used oil analysis from a DI engine that has shown an oil could go further than 7,500 miles. Most agree that on DI engines, 5-6k OCI is about the limit, even with synthetic, due to fuel dilution problems destroying oils in that short amount of mileage. My ecoboost sure does dump alot of fuel into the oil after 6K run.
