Heck ya, another oil thread Would you use Kirkland Oil from Costco?
I loves me a good oil thread.
the 4.2L = Engine oil, SAE 5W-30 meeting spec WSS-M2C-913B
Ford says this about that:
The Ford M2C913-B specification is released in Europe for initial fill engine oils used for lubrication of spark ignition engines using gasoline and for compression ignition engines using diesel fuels. The specification is also used to define engine oils for servicing Ford engines where applicable. The oil shall meet all the requirements of the ILSAC GF-2 and GF-3 specification, the ACEA A1-98 and B1-98 specification and additional Ford requirements.
ILSAC - GF5 is fully backward compatible with GF - 4, 3, 2 etc...
The 5.0 spec is WSS-M2C925-A is also ILSAC - GF5 compliant
Kirkland oil found in the links below meet ILSAC GF5
Krikland 5W30 Fully Synthetic oil can be found here:
https://www.costco.com/kirkland-sign...100527865.html
Kirkland 5W20 Fully Synthetic oil can be found here:
https://www.costco.com/Kirkland-Sign...100518854.html
and 0W20 here:
https://www.costco.com/Kirkland-Sign...100518855.html
10 quarts for $30 - So would you use it?

The only problem I see is that since there is zero information about what type of oil it is or even a clue to its longevity, you dont know how long the oil change interval should be.
The other problem is that its only $4 less than the Jaguar approved Pennzoil that meets the Jag spec for 4.2 and 5.0.
So it would be an expensive gamble.

Possibly an expensive gamble in more ways than one.

And yes, the language is weak on the web page: "Protects against high-temperature shearing to maximize oil life even in long drain intervals (Always consult owner’s manual for recommended drain interval)." But I think the risk is low for our engines with any oil that meets ILSAC GF5 specs.
Is there even a recommended interval in our owners manual to change the oil? I don't see it in my online manual. Surely 10,000 miles should be fine using a full synthetic, but there are also driving conditions to consider. Daily drivers, hard riders and garage queens all should be changed more frequently with the latter being more dependent on seasons vs miles.
Also as I do my own oil changes. I avoid such dings dents and mechanics with gorilla hands. Saving 80 cents per quart (vs Castrol or Pennzoil on sale with rebate) isn't worth it to me.

If you change it frequently enough and don't do anything unusual with the car, any oil that meets the spec will be OK.
Would I race on such oil or take it to max service interval? Probably not.
Also, I can't make numbers work. Engine replacement is $10K on the low end. Over 10 years ownership, how frequently do you need to change oil for the savings to add up to the cost of an engine swap?

I am convinced that study of psychology and rationale could use automotive fluid choices as a standardized test for broader things.
I dont mean false economy either, such as this oil if changed at 6 month interval, is actually twice as dear as the Jaguar recommended alternative when accounting for cost of filter. I mean paying more for an untested claim.

You can do all kinds of reverse math just based on that finding.
Sludge is the only thing that keeps me up in any engine, from a performance perspective.

Psychology did study it. To summarize: people create 'buckets' of needs and operate on % of 'volume' and not based on absolute values. So if your oil change total budget is $200 a year, saving $20 is illogically seen as a big deal and a worthwhile risk.

There seems to be some need to believe in big conspiracy, even when all other criteria of savings and such are met.
The Ftype forum is a great example, I regularly see someone discovering Mobil1 as the better choice for their new car, despite Mobil themselves advising against it.

You are responsible for what you wrote. I am responsible for what I understand.
P.S. Corrected typo created by Automatic Spelling Correction. Sage, not stage, advice.

My sister in law is in charge of the Costco account for a Fortune 5 company.
She says that no one is as strict on them as Costco. Many things they do at other retailers they cant do at Costco.
They do their own testing and demand 2x of whatever the other guy is getting. So if a laptop comes with 1 year warranty everywhere, at Costco it better be 2 years.
I learnt this lesson recently. I have to throw away my dream refrigerator and we never used it!! shame.
Bought it so that we could plan the kitchen we are building, had it plugged in but empty for a year. Needs a new compressor for a $1000.
Call Lowes they say I had a 1 year warranty (it took them 2 months to deliver)
See the same model at Costco, 2 year warranty and 10 years on the compressor.
Never again.
