Dealership put 1.5L spec oil in my 2.0L

[RSH]

As inconvienient as it is, take yout sport back to the dealer and have them correct their error.

You are a lucky man. The dealership I bought my BS from I would never set foot in again. My local dealers service and parts dept. employees you can tell all hate their jobs and treat the customers accordingly. I just deal with them as little as possible. Any job I ever hated I quit and found a new one.

Another reason for doing your own oil changes. Unbelievable stupidity at dealerships.

Agreed, I'll take knowing what's put in my car over a free oil change any day, I honestly can't remember the last oil change that I didn't do myself

Totally agree. I'm 79 and still do oil changes and tire rotations on both my vehicles. It takes me a little longer now, but I know it's right.

My Ford service is very good. However, the parts department wins the bozo award for being dumbasses. You are correct about finding a good one.

There is a reason the Ford engineers made the distinction in the two engines. I would take it back. Another reason to stay away from stealerships.

Since they made a mistake go ahead and have them rectify it.

I would not be too stressed about it though. I have a 20 year old 4.6 in a Mach1 (10:1 compression) that ford specified 5w-20 that I have been running 5-30 in for the majority of the cars life. My 21 Coyote has a 5w-30 (12:1 compression) requirement unless you are tracking the car then 5w-50 is recommended. Yet the 2019 Coyote I had previously specified 5w-20.

i have never experienced an engine failure running a different grade oil from what was spec’d by Ford. Mostly concerned with clean oil and the correct amount.

Guess I won the lotto. My dealership, sales and service, have been terrific and a pleasure to work with.

Same here, ROWE Ford in Westbrook Maine has done right by me.

Using a thicker-than-specified oil is not as dangerous as using a thinner-than-specified oil. With a thicker oil you might see increased wear on the oil pump, which was designed to pump thinner oil, and on internal parts during startup as thicker oil will take longer to get to all internal engine parts.

With thinner oil, the danger comes when the oil gets hot, which is most of the time you are driving it. The engine is designed to operate with the oil pressure within a given range. This ensures enough pressure on the oil moving through the engine to force it into all the places it needs to go. Thinner oil is easier to pump, so your pump needs to move more fluid to generate the same pressure. If your pump cannot generate pressure because the oil is too thin then oil will not get to all the places in your engine it needs to go.

The reason Ford specifies 5W50 while tracking your Coyote-equipped Mustang is because oil gets thinner when hot, and oil gets especially hot on track days. 5W30 oil will get thin enough on a track day to adversely affect oil pressure, so Ford recommends higher-viscosity oil.

The bottom line is do not drive your car with the wrong viscosity oil in the engine, and ESPECIALLY if the oil is lower-than-recommended viscosity.

Well aware of the reason ford specs the 5/50.

Yet on the coyote for the regular use it’s 5/20 and another is 5/30.

Just saying I don’t foresee catastrophic engine failure out of one oil change. Maybe if you choose to run the lesser grade long term.

They have a remedy because the shop made an error. By all means have them correct it.
I just would not stress about it too much.

Ford recommended 5W20 for the Coyote engine up to the 2021 MY, likely to meet a fuel economy target. That means the engine was designed--or at least determined via testing to be SAFE--to run a thinner oil. Ford's recommendation for HIGHER viscosity oil in later MY cars with the Coyote engine is not evidence it's safe to use LOWER viscosity oil in an engine not designed for it.

Yet it’s the same engine….

All I am saying is don’t panic.

The oil debate is raised on every forum I’ve ever been on. Brand/Dino vs. Synthetic/ viscosity/change interval….etc…

By all means use what the manufacturer specs in the manual especially when under warranty, but in this case no need to get too worried. Go have them fix it.

And you’re right the 5/20 was spec’ed for fuel mileage. Had a ford engineer at one of our club meetings 20 years ago that verified that.
He ran 5/30 in his own cars too…

I'd love to run 5w30 full synthetic. It's hot and humid here for many months and some high 20's overnight for a couple of months in winter with a worse case scenario 35 degree day a few times. Usually low 50's.

Now will the dealer service agree?

 

[Jbrad88]

Don’t see why they wouldn’t?
Pretty sure the Dealer oil change places stock the Motorcraft Synthetic…I’ve been running Mobil 1 in my 21-Coyote (no infamous tick either) and Amsoil in my 03. Went Mobil 1 in the BS on its second change.

The Bronco Sport has to be one of the hardest vehicles to change the oil. The exact same looking vehicle might use one of four different viscosities and the capacity varies even on the exact same car by build date. The best thing any owner can do is know the correct oil and capacity required for their specific car, because most techs sure as hell can't guess correctly and neither can Google.

I'll have to check my BS oil cap, but it used to be that the oil to use was written on the oil fill cap.

No excuse for a tech to get it wrong.
