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.

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.

Worried about it leaking during storage. It's in a plastic bag inside a cardboard box
Good call. Don't store it next to the ninja throwing stars and build-your-own cactus kits. LMAO

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.

Quote from pruks :
You should look into FCPEuro, everything you buy from them is lifetime guaranteed, yes even brakes/oil etc. You have to ship the old oil or parts back and they will send you new
Just changed my wife's brakes, plugs, and all filters. Cost me about $800 in 2017 for everything. Cost me $90 this time for the return shipping, which was great seeing the brake kit cost $1500 now lol.

We buy the oil for all our cars there. Just changed my tundra. Was like $90 in oil and it'll cost $15 next time for the shipping.

Love FCP, best place around.

Quote from Pi.314 :
motor oil is usually 5quart (1.25 gal).

6 gal = 4.8gal
$46/4.8 = $9.58/5quart jug

GREAT price and without rebate.
too bad i already bought 2 jugs from Penzoil (waiting for rebate...)
Uh....6 gal = 6 gal. Not 4.8 gal.
I think you meant to express that 6 gal= 4.8 5-quart jugs.(?).
Easier to arrive at per quart price by dividing cost by number of quarts. ($46/24= $1.91)

Not really cheap although some might have a bulk discount or prepay for x discount, blackstone did. You might pay less if your vehicle is a gasser vs me having a diesel, I don't really know. Plus there are different tests you can addon as well. There are a couple companies that do it, I've only used blackstone (https://www.blackstone-labs.com/). I grew up with the 3k or 3 months and it gets changed. Oils have changed A LOT! since then. I don't even go by the oil life monitor on my pickup. It gets down to zero and I reset it and keep going. Longest I've gone was 10,508 miles and the summary said I was good. Blackstone shows you a couple of your previous tests on the pdf report they send too. I should probably do another analysis since it's been almost 2 years since my last one.


*edit* Their price list page
