Oil Change Advice

❔Question

I have a 2022 Mustang EcoBoost that I bought in April of last year. I bought it and started having health problems soon after, that lasted until a few weeks ago. I’ve only put about 425 miles on it, and I’m being prompted to change the oil by the dealership, Ford, etc. Should I go ahead and change it? Wait? I know oil breaks down, even if you’re not driving a car regularly, and I don’t want to ruin a new motor or void the warranty. Any and all advice is appreciated. Thanks in advance.

Check how the oil looks. If you don’t have confidence on the oil quality, change it.

If you've only driven 425 miles you don't need to change the oil. It doesn't matter if it's been a year. I can guarantee you that the oil looks brand new.

I love seeing someone downvoted for saying something reasonable. Time doesn’t ruin oil like people seem to think it does. I had Valvoline full synth in my car for a year and a half and the stuff was in good shape, also had 10k miles on it. Metal wear particles were low, viscosity was unchanged, additive package was low but still there.

Since it sounds like this guys car is still on its factory fill, I’d say change it just to get the break in metals flushed out. This was something I really wanted to test out with my aunts Honda crv since she only drives it 2-3k miles a year, but i unfortunately couldn’t fit my oil sampling tube down the dipstick hole, it made a real funny bend that the tubing just didn’t want to pass down through.

I have a couple people that love me so much they downvote everything I post.

Oil is cheap. Engines aren’t. Change the oil.

Why? That oil is fine.

You don’t know it’s fine after a year unless you send the oil off for testing. The acid neutralizers and anti-foaming might be depleted. The risk not worth it.

It is not going to go bad in a year. You seriously think it's in there being "acidic" hurting the engine?

OP and you can do what you want. I have a GT that is a garage princess. I give it two oil changes a year.

Contact Ford's corporate warranty department (not the dealer) and ask them for an opinion. Get their response in writing. I'd hate to see you have engine trouble down the road and Ford not honoring the warranty.

When did you last put gas in the car?

Is it brand new only 425 miles on it or that's how much just you put on it? Are there service records from last oil change?

About four months ago.

Brand new, only about 425 miles on the engine, period.

It could be the old gas causing running issues, I would try a fuel additive octane booster and topping off with the highest octane gas you can get at the local pump.

Though if brand new it should still be under warranty. Why is the dealership telling you to change the oil? They should be doing a serious diagnosis. If still under warranty I wouldn't do anything myself for fear of somehow voiding the warranty.

It’s not giving me any problems, and it runs great. I’m just wondering about the oil changing.

They’re telling me to change the oil, as it’s estimated to be past time to need an oil change.

Oh gotchya misread. If the dealship has already said to do it I would. It doesn't make sense to do it because conventional oil lasts 3-5000 miles buuuut again with warranty, if there is a problem down the road they might come back and be like "well we told you to change the oil but you didnt...now this happened and we're not liable to fix it." I would just have the dealership change it, I would think first oil change is complimentary. Least it was when we got our Dodge lol

You haven’t even gone through break in yet / I would drive to 1k and then service - Service again at 2500-3000 -

You should go change it, especially on a brand new engine.

Break in oil change on a new engine is pretty early. Also let's them look it over and see if anything is wearing poorly. This change is more to remove anything from the making process of the engine, any dirt or debris from machining and assembling.

Install a catch can happen if you can too.

Install a what? A catch can happen?

Aren’t you supposed to change it at 1k on a new motor after the break in period?

I’ve never heard that, and I’ve had my share of new Fords.
