Oil change

[Tcnarber]

How long after you get your Mustang, or for those that have their Mustang did/will you change the oil? I was going to do this immediatley, but I have read the initial oil that is placed in a new engine "break-in" oil should be ran for a complete oil change cycle.

Yep, I've read this numerous times as well. There's no need for an early oil change, and in fact it may be detrimental to the break-in process.

How would it be detrimental?

If they put any special additives in it to help with break in, it could hurt changing it too early. Although I'm reaching there because I have no idea if they do that.

How would it be detrimental?

I think I'm going to change it at 3k. That should be plenty to get broke in. Then probably 5k there after. Most likely Mobile 1 synthetic, or if I have a chance to get in contact with an acquaintance that works for Amzoil, I'll get that.

Ford spends a fair amount of money honoring their warranty. They also understand a strong second hand value is good for the company. They do a pretty conservative on what maintenance is required when to both minimize their warranty costs and maximize second hand value.

You can feel pretty good following the instructions in the owners manual.

I changed mine yesterday at 1500 miles, I will now do 5000 mile intervals most likely. I used the Motorcraft 5w20 Full Synthetic and the Motorcraft FL500S filter. Changing it was a breeze with ramps on the front. Oil filter is easier to get to in the 15, requiring only on one bolt to be removed which lets a small "skid plate" flop down.

I am considering doing mine soon. However i would like to keep the stock stuff in longer if it has a break in additive. I am concerned about creating an engine tick that other coyotes have experienced by changing the oil too early.

Only reason I want to change the oil so quickly is to get all the materials that are in the oil from the break-in..out of the car. Which brings me to my next question. Why is it said and highly recommended to change your oil out as soon as you can after break-in? shouldn't the filter catch all the metal particles that are sheared off during break-in? So technically couldn't you just change out the filter and be fine?

Ford doesn't recommend changing the oil before your first scheduled interval. Considering that it's way in their favor to have your motor be as healthy as possible - I'd listen to that advice.

I appreciate your comment, however I'm looking for more than just the generic "listen to the manual" statement. I fully believe you should keep the break in oil in. So there are two options, replace it with whatever the factory puts in it to get rid of any metal particles or change out the filter

What's the first scheduled interval? In my 2011 it just says "oil change every 10,000 miles" and no other scheduled maintenance whatsoever.

I'm not an engine builder or a mechanical engineer, but it's my understanding that manufacturing and clearance tolerances of modern engines are such that if you have enough particulate to cause damage in the oil, you have other problems.

That being said, when your car says change the oil, change the oil. I know it's not sexy, but some stuff you can really just take what the manual says and go with it. It kind of goes against the enthusiast grain to listen to the manufacturer about performance, but I'm confident on this one. I changed the oil on my 11 Coyote after 6,000 miles. I had plenty of issues with that car, but the motor was rock solid for over 70k miles and didn't consume much oil between changes.

trying to decide if we really need to run a full synthetic oil or would Castrol GTX 5w-20 be acceptable? I have used Castrol in all my other cars and have not had an issue. I know they are building these motors with tighter tolerances these days and was wondering any pros/cons on oil selection? thank you.

There is a thread on svtperformance that promotes Amsoil SS and has a bunch of oil analysis done on various different oils. All done on the 5.0 Coyote.

That should get you started. Most "Full Synthetics" are far from it using lower cost base stock with better additive packages to get the lower cost base oil to perform closer to true synthetics.

This is a hot topic. If you care to do the research you will find some good products to use. If you actually perform maintenance regularly and do not abuse your car you could probably get away with any oil meeting the Ford spec for the engine. I bet other parts of the car would fail before the engine. Enthusiasts on the other hand will want the best even though the best is probably overkill for 99% of the cases.

You don't need a full synthetic. The Motorcraft synthetic blend is a good oil. Your motor was engineered and built to specifically use that oil and it performs well.

That being said, as long as you keep the viscosity the same and don't just use dino oil, you're going to be fine.
