Is this oil suitable for a 2019 fiesta st usdm model with the turbo 1.6 liter?

It is more than Adequate* If you really want the lowdown on how it Performs....After 5k send in a sample to Blackstone laboratories for a review.

As far as I can tell, it meets Ford Spec WSS-M2C946-B1, which means it is suitable.

One of the better, 'on the shelf', affordable oils out there.

Our engine oil Ford WSS spec calls for a 5W-20, but many (most??) of us are using a 5W-30 weight oil most of the year, if not year round, as long as we live south of the Arctic Circle.

I've long been a Mobil1 user, any reason to not keep on that direction?

^^^ALL of the 'on the shelf at Wal Mart', labeled as 'fully synthetic' (even though technically they are not) are really good products.

Many on here (and elsewhere) seem to think that Pennzoil Platinum Plus (even though the plus is not at Wally's, and is a bit harder to find than the regular Platinum) is THE best of the non-boutique (super premium, truly fully synthetic, full Group 4 and/or 5 base stocks used) oils which can be 3 times the price (or more!) of the readily available, usually found on the shelf at retailers, oils.

I personally have an extreme case of OCD severe 'overkill', so I use one of those mail order only, exorbitantly priced, truly fully synthetic 'boutique' engine oils (Ravenol DXG 5W-30), and change it out once a year or every 4K miles.

I was doing 5k OCI on my Mini, but they had a tendency to use oil.
I do 7,500 in our Expedition Max, and was planning on the same with the FiST.

If Mobil1 hasn't given you trouble then no reason not to keep using it - I come from Subarus, which did not get along with Mobil1 back in the day, so I use Pennzoil Platinum.

I remember long ago reading something breaking down Pennzoil Platinum being SLIGHTLY better on turbo direct injection motors, but I have long since lost the link, I've just used Penn Platinum on this car ever since and I've never had any trouble.

So the Magnatec 5w30 meets the ford requirements for the 1.6 liter turbo fiesta?

According to ford, no but most of us use 5w-30. Looks like you’re in cali where it’s warm so 5w-30 is totally fine.

So it won’t harm my engine?

It has already been said a couple of times in this thread that this oil will work fine in your car. Relax and use it.

Correct.

 

[rallytaff]

I've been using full synthetic 5w-20 as recommended in my car since new!

It is one of the lower viscosity 5W-30s out there, so it is very close to the upper range of the 5W-20 spec anyway.

Now, if you wanted to use the regular (not their black bottle 'street', or European versions) Red Line 5W-30, and were not open tracking the car, that one might be a bit too viscous for daily use, even in a hot climate, since it's actual viscosity is much closer to a 40 weight range spec.

(That Red Line is probably not a great idea anyway since it has a very high calcium, and sulfated ash content, NOT something we want in an LSPI prone, turbo direct injected engine, even though Dave the head 'tech' @ R.L. says otherwise.)

I think the brand is fine, generally any name brand full synthetic oil is acceptable. Asking for a recommendation about a specific brand on a car forum is asking for trouble, it's like asking a question about religion or politics, except probably more controversial.
As far as the viscosity goes, I personally feel more comfortable with the recommended viscosity, 5W20. I know that modern engines like ours have a lot of very tight tolerances, small spaces between certain parts, and that that is sometimes a reason that manufacturers recommend lower viscosity oils, to get into those tight spaces .
However, I know a lot of members on here use 5W30 and are comfortable with it.

 

[M-Sport fan]

What everyone has to realize is that within any given SAE viscosity label (5W-20, 5W-30, etc.) the oil producers are given a fairly wide range of actual measured viscosities which are acceptable under that weight.

Therefore, there can be a 5W-20 oil which is heavy enough to be just about a 'light' 5W-30 by actual lab measured specs, and there are some 5W-30s which are light enough to be at the top of the heaviest allowed 5W-20 specs.

WHY I do not like using the general SAE weight labels, and look more at the published viscosity specs (cSt @ 100*C and @40*C, and the HTHSV specs) when choosing an engine oil.

Yes, there are many other factors.
One of the most important is to not get too far away from the automobile manufacturer's required spec (like the Ford WSS- numbers), since besides measured viscosity, they also take into consideration additive and detergent/dispersant packages, as well as anti-wear and anti-friction package requirements for any given engine platform's; valvetrain/bearing clearance/etc.

There can be great differences in those above requirements, and additive packages between specific USDM, German, and Japanese/Korean engine lube specs, even within the exact same measured viscosity oils.

Oil threads. Tread very carefully.
