I've been using this oil exclusively in our Ecoboost engines. What is the group's opinion of this oil? I like it for its value.

I personally think that you might as well step up to Quaker State Ultimate Protection since it isn’t that much more expensive. IMO QSUP is one of the best deals out there at the moment, just under $24 for a 5qt jug at Walmart. I bought a jug to go in my Honda for the next oil change
I have run it a couple times. Its Dex 1 Gen 3, 5w-30 is fairly high in the 30 weight viscosity and its cheap. Whats not to like?
I have decided to use this in my wifes Mazda CX-5 (non-turbo 2.5L) at her next oil change and run it for 5K OCI (0W-20 flavor.) I have it on Amazon Subscribe/Save for $20, so a couple dollars cheaper than Walmart if you do it that way. I thought about the Ultimate Protection, but not on Amazon S&S and since I'm changing it every 5K, might be a waste.
Down the road from me, they're building a Costco. So, I may look into Kirkland. 5Qt jugs in a 4 pack for $60 is pretty good (twice a year they do that I think?) Store doesn't open until 2025, so a little bit of time yet.

540 rat ranks qsfs 5-30 at #11. This is the latest dexos 1 gen3 released in spring 2023.

I like it. Good oil. Run the 0w20 version across half of America. No elevated wear.
QSFS 5W30 is one of my go to oils as well.
EDIT: And 0W20 & 5W20 as well

Why don't you try 5w-20? Not 2 thick and not 2 thin. .02
I believe it... Ford went back to 5-30 for a good reason. I changed the oil in my Explorer (2.3 ecoboost) and my wife thought the car was leaking gas somewhere because of the fumes.. Nope, just the oil, nothing to be alarmed about.
Thanks, I see.
Odd, Your signature vehicles say Kendall GT. You have another fleet you maintain professionally?
QS is a decent oil. Ran the FS 10W30 a few times and saw smooth running and improved fuel mileage over Castrol or Valvoline.
I does seem to be a bit "batch dependent" like fine wine as my third jug wasn't as goodest as the previous two.
Must be them pesky base stock interchange shenanigans
Lake Speed say's PUP is better-er. Well I say good enuff is good enuff!
Plus I have a Pennzoil aversion. Ha! what a Shell game ... literally

That’s a sweet price.
QSFS is on the high-end of the viscosity range for a 5w-30, is Dexos1-Gen 3 licensed, appears to use group III base stock (as per Lake Speed Jr.), and is competitively priced.
