S550 5.0L 1st Oil Change and Oil Consumption

Hello All,

This is my first V8, I purchased the car new and basically followed the break in procedure exactly. RPM's varied but never went above 4K for the 1st 1000 miles.

After 1000 miles engine still has never been bounced off of the red line but it has seen the upper end of that rpm range especially after getting a roush exhaust

What is the recommended mileage for the first oil change. I am currently at 2450.

Also, I noticed the Oil level which was previously almost at the top level is now reaching the mid point of the measuring hatch. Is it normal to consume a little oil?

It is normal for them to consume a small amount of oil. Especially if you drive them hard. I do my oil changes every 7000kms so I guess 4000 miles but mine isn't a daily driver. Depending on what you do with your car I recommend synthetic and a good filter. I use the ford racing filters. Upon taking numerous maintenance courses for work it always comes down to the filter is the most important part.

The manual says the mustang oil should be changed at 10k. Let me know if I'm incorrect..

It sure wouldn't hurt to do first one at 3000=5000 miles and then do the regular schedule. Get rid of them first wear particles.

Up to 10K/1yr depending on driving. You'll find different opinions I'm old school and prefer the 1st one early (1k) but admit it's just opinion and it helps me sleep. The other suggestion is I like to pull fuel pump relay/fuse to allow 2 10 second crank cycles after each oil change to allow the pump to prime. Once again just my .02 OP, glad you check it not every one does

I would do an early change, like now, and then follow the oil life monitor -- it will tell you when an oil change is due.

For "extra protection" use an extra good oil. I like Mobil 1 Extended Performance because it is a good synthetic oil and reasonably priced at Walmart in 5-quart jugs.

You can also get the motorcraft filter at Walmart, though the Ford racing filter wouldn't hurt.
