It's all made by Warren Distribution. They make Kirkland, Super Tech, Amazon, and many other private label brands. It's good stuff.

Why would you ever need to do an emergency oil change?

Quote from CreditGuy :
If this was meant as sarcasm, it was brilliant! If you are being serious, then it's TMI for most of us. 😊. I just change the oil regularly in all my vehicles and put in the correct weight and make sure to change the filter each time (I occasionally cut them open to inspect them as well). Three of my vehicles have 200+ k miles and my 30 year old pickup has 130k so I assume all is well. They all run great so I'm planning on 400k at least for all but the pickup. I feel that if I get 400k then I've done well.
That's usually the case. What we nerds mean is to simply make sure you're running an appropriate spec for your engine. If you have a low-power, naturally aspirated NON-Direct Injection (port or port + DI) the oil you use isn't (may not be) as important as if you have a high-strung little DI turbo engine.

It doesn't take too long to look up the spec you see on the bottle and make a quick educated guess about whether it's appropriate. For some makes (eg German makes), there are spec's that supersede the basic American Petroleum Institute (API) spec that needs to be followed. These are listed on the bottle.

Example: follow the manual and buy a specific rating of oil for a German make. Keep following that. For my low-powered, nautrually aspirated, port-injected Subie, it's the basic, universal API spec. It may have started as the designator SM when I bought it, but SN (literally the next letter in the alphabet) supersedes SM. So in and so forth. After a certain period of time you literally can't find an actual oil that matches the old spec.

For my turbo Subie I choose more than the listed API spec, under the assumption that something like the GM Dexos spec may further help mitigate low speed pre-ignition (LSPI). I'd likely be fine using the generic API spec, but adding a spec that's design criteria and includes something beneficial won't hurt and may help.

The same can be said for using a super robust oil for you beater. It's not going to fix anything if it's already dying, but using a heavy duty oil may provide an additional layer of protection to keep things going a bit longer.

Finally, this isn't for you. Whatever you're doing, keep doing it. For those who have engines with specific needs it behooves them to take a day and search the internet about what the owners manual spec means. As an example the owners manual might spec the older API SM, and one could easily be confused when they see a later spec. That's admittedly an easy one to figure out. ACEA and manufacturer spec's might be tougher to decipher.

FYI anything API SN Plus or SP is designed to protect against LSPI.

Where did you see they were dexos2? That's a diesel spec fluid which I don't believe either of these are. The little green icon looks like a 2 but it is just a logo and you'll see a small 1 inside. I believe they are both dexos1 Gen 2 (which also protects against LSPI).
The D2G2 is in the picture of the bottle, unless I'm blind. I like that an oil can be API spec'd and have a D1G3 designator.

I bought KS D1G3 when it was on sale a while back. It's what's in my turbo Subie as of a few days ago. 5 qts KS, 1 qt M1 - both D1G3.

It's not D2G2, it's D1G2. But, the newest spec is D1G3, so any oil produced since basically Sept. or October of last year, is G3. It's most likely just the old pic and they haven't updated it.

I've had no issues with Costco oil. Supertech is also very good, but getting pricey. Supertech's 4 stroke oil is next level good, beating out Honda's 4 stroke oil.

newbie question, after purchase, are you guys changing oil by yourself? I just started to learn how to change bulbs/filter of car, wondering if oil changing is too challenging, or does some store offer such services?

Good catch and sorry for the mistake. I missed the little 1 at the bottom; thought it was a 2.

Its not too difficult but can be messy. You can purchase the oil and filter and call the shops around for the labor charge for an oil change where you bring the oil and filter.

How hard an oil change is depends on the vehicle and the tools you have available to you.

For my Subarus the oil filter is on top of the engine - couldn't be much easier to change and results in zero mess. Some of my older vehicles had the oil tucked up on the side of the engine - always made a mess.

I also installed a little Fumoto drain valve to make it even easier and less messy. I only have to do the following:

1. Jack car up from one side and add jack stand for safety

2. Slide used oil catch container under the engine drain pan

3. Turn drain valve lever to commence drain.

4. Lower car

5. Remove old oil filter and clean seating area (I only change the filter every other interval - Fram Ultra)

6. When drain is complete, shut drain valve and clean the few drops of oil on the nozzle

7. Fill new filter maybe halfway to wet the pleats and install, if applicable

8. Add oil per manual (5-6 qts depending on which Subie) and check level

9. Start engine and run for ten or so seconds (how long it takes for the idle to come down for me)

10. Check oil level and add as necessary

Anyone can do this - I have faith in you! I've done it in the grass with only hand tools before and im far from the best shade-tree mech. Lol

Some shops might do an oil change with your oil and filter, charging you only for labor and maybe disposal fees. If I wasn't inclined to change my own oil I'm not sure I'd do this unless I had a very good relationship with the shop, because it's your ass if something goes wrong and there's any possibility of it being the oil. Eg, they didn't put enough oil in, you don't check, they blame it on consumption due to your choice of oil.

Yeah you got fooled by the green swish. There is a tiny white number 1 in that swish so it is a dexos1 oil.

dexos2 acea/diesel fluids have a blue swish and a white 2 in the label like this bottle

jacking up the car and put them on jack stands, lol, that right there will be a challenge for a lot of newbies
