There is nothing special about a Jaguar engine, its just an engine. (I have torn apart and built many engines therefore speak from a position of at least some actual knowledge).

Ultimately to each his own. But our cars are just cars, I have had the suspension out, nothing extraordinary. The V8 is just an overhead cam V8, nothing super exotic about it. The trans is just an off the shelf unit, nothing special, use fluid that meets the spec...etc etc etc.
While I love my Jaaaag and it looks super sexy and performs well and is comfortable and nice inside it is not anything exotic mechanically.

It wasnt about warranties- it was an IQ test....
This oil is made by the same company that AmazonBasic oil and Wally World (Walmart) oil.
Which maybe alarming to some.
The point was that the same exact product even from a giant like LG at Costco, requires LG to double their assurance (and quality) when supplying Costco, its the Costco way.
That and the $1.50 hot dog and coke was more information than can be found on the oil label.

Because sometimes there are hidden gems.
Like the least expensive oil on the market right now is so damn good that it received the official Jaguar approval retroactively.
$20 oil that can be left in the engine for a year according to JLR.

My take, if one changes their oil often and relative to the severity the engine is exposed, minimum those oils not part of the main stream will suffice. I would ask anyone to run a "AutoZone" branded oil for 3 - 6 mos. Have it analyzed. Do the same with your first choice well known branded oil, given the same use and conditions and have it tested. What are the results? Probably not much to cause one to worry. I'm a three season driver, then change the oil. Then, for only fun runs, a few Cars 'n Coffee" shows and date nights.
To me, the worst killer of rotating internals is not getting the engine up to temps for an extended period.
A case in point, how many here has read the ADs, wherein, someone is offering a car for sale....
The Ad goes something like this.....
This XYZ car is over 10 years old, has only 15K miles and driven by my grandmother to church on Sundays. Wow, little use, driven by their grandma, what a deal at 50% less than another similar car with 4 times the mileage? Wrong! I would expect, there is huge "sludge" build-up in that engine and, most likely, the oil returns to the crank case beneath the valve covers are clogged.

So of course I took off the oil filler cap and ran my finger around the inside, and it came out covered with black peanut-butter-chunky-style oily gunk. I asked the seller "When did you last change the oil?" She answered "Oh, I add oil all the time!" When I repeated the question, she looked at me all dumbfounded and said "You're supposed to CHANGE it???" No doubt the oil bypass at the filter had been bypassing for quite awhile.
Yeah, my sister didn't buy that Dart.

Decades ago, my sister asked me to join her to look at a car she was interested in buying, so of course I agreed. The car (Dodge Dart Sport) looked great on the outside and inside. The chick selling it decided to start it up to show how easy it started before I had a chance to look at anything. The car started blowing out huge clouds of blue.

Engine flushes clear out ports fairly well imo, even on cars driven by lil ole ladies. In the 70's, we used kerosene on diesel engines for a flush. Blew smoke like a son of B while running it, then a fresh change of oil and all was well. This was considered proper procedure/ policy when I was a bus mechanic in Denver. Today, I just use the engine flush before putting her to bed for the winter. I'm still amazed at how filthy the oil is with as little driving as I do.
I wonder what the reaction would be to a thread if Costco started branding Kirkland tires?

Well, just to add a data point, this topic has reminded me that I bought some Kirkland 'Signature' Professional Glossy Photo Paper distributed by Costco a couple of years ago and it seems I still have most of the 150 sheet box left. When I think back on it, what occurs to me is that although I thought I was getting a real bargain at the time what actually happened is that I soon realised that the performance of the paper was way, way below my expectations after reading the blurb and seriously below that of the recommended but more expensive paper. Now I've dug it out I think it will hit the trash tomorrow. Now, maybe their business model has changed dramatically in the last couple of years, maybe when it comes to lubricants they have a superstar buyer who only goes for the upper echelon of oils but maybe, just maybe, it is just very average cheap stuff marketed well to look like it is more than it actually is. There is no such thing as a free lunch, fill the sump of your P&J with low cost lube to save a few dollars if you will because after all, you are such a canny buyer but for my part, I'm happy to comply with the manufacturers recommendation. It is, after all, a relatively small part of the overall running costs.
