Our shop uses these type of ecoboxes. We're pretty heavy handed with them and they've never leaked. Some of them stay opened on the shelf for up to a year without issue.

I had not heard of this brand, so I looked at the Petroleum Quality Institute of America site. The additive packages look good for this oil:

Decent amounts of moly, boron and zinc.

I've often wondered about oil tests, but have never researched. Do you have a link you could share for cheap testing? I'd like to solve an argument with my mechanic over manufacturer recommendation and his (what I think is) old school thinking.
Your mechanic has probably seen so may engines ruined by oil deposits clogging vital passages and filters. Or carbon deposits building up on rings and valves, causing engines to 'burn' excessive oil, which can also ruin other components like spark plugs and catalytic converters.

It's the cumulative build up of deposits that 'old' oil leaves behind in your car that's the problem.
Meanwhile the oil that's in your car today could 'Test' just fine. That doesn't mean your pistons rings aren't a ticking time bomb because you went 10K miles between oil changes.

If u drive Uber and change your own oil, it will be good deal, I drive more than 40k mi per year, change oil every 6 to 8 weeks, or if you own a big V8 like Toyota 4.7l that use more than 5qt. But I guess once open, better use them all asap
For a modern synthetic that's very frequent and likely unnecessary oil changes. You should sample at your next change and send off for eval. I bet you are wasting a bunch of your time and money

Thanks for posting. I have an LS460L that takes 9 quarts of 0w-20…also an RX350 that takes 7. These boxes will give me 2 oil changes for the 2 cars.

This is about half the price of Kirkland and any other full synthetic oil I can find.

So, do you think it needs refrigerated after opening?
Does it say that on the box?
My milk carton has that and I always do it.

Looks like realistically 5w-30 was only ever available as conventional. super deal in 1992. Today not so much.

people don't change oil at 3k miles in the year 2022.

I use 6 gallon boxes of oil like this at work and honestly I prefer it over 55 gallon drums. I can't speak for these but at least with the ones I use at work when you shut off the valve it doesn't drip. I have a box that I think is about 5 years old and still works just fine.

It has a open / close spout, you can use as much as you need each time.

My question is what is the regular price?
Okay... That makes it better.
I thought these were plastic bags that you cut open

Could you imagine. That would be a huge mess. My garage would look like the Gulf of Mexico after that oil leak back in the day

Black oil vs brown/amber oil? What's up with black oil?

Quote from Chevyguy85 :
Saw some comments on shelf life. Oil will last for quite a while (years/maybe indefinitely depending who you ask) when unopened and a while after opening but closed. I buy 5 gallon buckets of 15w-40 when it goes on sale and combine that with Mobil rebates. I'll have 2-4 five gallon buckets of oil on my back porch in Florida and I haven't noticed any "go bad." I've done multiple oil tests with 5-10k miles on the oil when changed and they've all come back fine and still have additives left over. 4 five gallon buckets amounts to 8 oil changes for me which means they are sitting on that back porch 2-5 years. In short just keep the oil sealed/closed and it'll be fine.

I'm not sure I understand your logic.

If your oil "tests fine" then why would there be a buildup of carbon deposits of "old oil" in your engine clogging it up?

If your engine is burning oil and creating a buildup of deposits then changing the oil more frequently simply won't matter. It's just going to burn that oil and create deposits.

If your oil has a lot of deposits and no longer protects the engine then changing the oil more frequently will be good for your engine.
