Click on the warehouse on the bottom of your app. Then click that you want to shop your warehouse.

I'm able to easily see that my warehouse doesn't carry most weights and that I'd need to order it online.

It's warren oil, the same people who make supertech. I'm thinking if you are changing every 5000 miles (especially given that it's so cheap to do so with this), it'll be no issues. But obviously, ymmv

Interestingly, from I can see, it's $30 for 2x 5qt in-store so online is actually cheaper. I really like that the Costco app lets you check in-store inventory and prices now.

Was hoping to see 10W-30 high mileage in the sale. 5W-30 will do

API SP. Good if you have an older car that lacks a turbo or timing chain. Everyone with turbos or timing chains should switch to an API SQ oil, if you want to improve your chances of hitting 300,000 miles. SQ has added detergents and purity that protects both components specifically. GM is using it to get their way out of the L87 camshaft failure debacle.
You're downvoted but I also don't know anything about cars lol. I have a 2018 Chevy volt. Google says this:"The 2018 Chevy Volt uses a 1.5L naturally aspirated (non-turbo) 4-cylinder engine with a timing chain. It requires Dexos1 Gen 2 or Gen 3 (API SP/SN Plus) rated OW-20 oil to prevent low-speed pre-ignition (LSPI). The engine is engineered to run at specific temperatures, making high-quality synthetic oil essential for longevity."Can anyone tell me if this oil is fine for my car? First time trying to change the oil myself!

Eh, in that huge engine he probably has a sump capacity of like 8 quarts that he can comfortably push out in terms of mileage.
He was replying to someone with a newer Sienna with the 2.5L , that's 5 quarts max. Realistically only 4 quarts actually drains out. To put a new engine in it's $8K or more. To do one extra oil change, it's $20 a year.

Can you expand on this further? The 5W-30 product says it's good in engines that call for API SP, SN PLUS, SN, SL and ILSAC GF-4A, GF-5, GF-4. The manual for my 2021 CX-9 turbo says I need to use API SM/SN or ILSAC GF-IV/GF-V. Wouldn't I be okay to use this?

Remember the FAR Pennzoil full synthetic deals from back in the day? Pepperidge Farm remembers (and so do I, since I still have two 5qt jugs of 5w-20 remaining).

You're on the link. Each jug of oil is $13 . Then I bought Purolator filters when they were posted here on SD for under $7.

Not the person you responded to, but my local mechanic only charges $20 to change my oil and rotate the tires...though I provide the oil and filter (which is always going to be my preference, anyway). Given that I haven't paid more than $15 for full synthetic and a decent filter in almost a decade, I think it's a good deal.

I don't see 0w-16 that the 2025 Toyota sienna requires.
Garage, Jack stands, .etc aren't included either

Poster above is says $20 for labor alone.

That was it...the actual item title does not say "motor oil" so that is why search did not find it (search must just check titles and not other information).
Better is to copy and paste the item # into search box

I have a F350 with a gas 6.2l I bought used. Did my first 5k oil change and the oil looked the same coming out as it did going in and it has 145k miles on it.
Not sure if that's relevant or not. Not all cars are the same.

You can't even change oil or know anything about auto repair? Go away already!
