For select and vital criteria, there isn't.

Under penalty of law they have precisely the amount of Alcohol By Volume (ABV) stated on the label.

If a consumer is comparing bottle A at 40% ABV to bottle B at 40% ABV, they are therefore identical in amount of alcohol. It would be false then for a person to say that one is 'different' or 'better' than the other.

If a person needed a liquid that was 40% ABV and no other criteria mattered, then 40% ABV moonshine would do the job.

BTW- not all moonshine is grain based.

 

Get a grip, Box, you must be mistaken! However, the description of the parson in Oliver Goldsmith's The Deserted Village comes to mind:
In arguing too, the parson owned his skill,
For 'een though vanquished, he could argue still.

I still invite anyone to take a mix of 10 conventional, semi and full synthetics, all the same weight, side by side and do a cold pour test, and then tell me which you would want in your Jaguar. (and not to worry, whether you are in North America, or the rest of the world, the atmosphere and gravity are still relatively the same)

 

hmm, I think that post-dates the S-Type and its oil spec.

Over here S-Types (there were a lot) fall off the road for things like collisions and rust. (Oh, and being a diesel with DPF.)

Use the oil you like. I'm using oil I like, due to it meeting jag's specs and being affordable. Everyone gets to choose

 

That wasn't the context - you've made it up.

 

Exactly. There's no mention of this spec being retroactive. The oil might be required for the latest generation of engines (and even that's still up for debate) but to think that there's some inherent benefit for previous generations of cars is a huge leap of fantasy.

To infer that a marketing alliance is now mandatory is the perfect example of baffling with bu**sh*t.

Pouring oil from bottles when cold as a meaningful measure analogous to engine life is the ultimate snake oil show.

 

So ASTM D-97 tests are snake oil? Where did you get your knowledge of oil? The only thing you're proving here is just how unlearned you are concerning the basic tests to determining factors of an oil's viscosity and ratings. I suggest before you continue to show us all in a public forum just how unlearned you are, you might actually do some research before typing. I'm still waiting for you to show us all one single conventional or semi-synthetic that meets Ford WSS-M2C913-B to support your assertion that "But not all oils that meets (and exceed) those specs are synthetic"

Sorry if that hurts, and I do hope you have a great day.

 

Have at the oil discussion all you like, but if this degenerates into a personal argument that will be the end of it.

 

Look both ways before crossing the street... Just sayin' False assertions with no legitimate method to support your position is not good information to have on a global board. Please be mindful of this as well.

 

I bought them and put them in my car.

No idea if they're still for sale 7 years on and frankly don't particularly care but they DID exist AND I USED THEM.

Now prove ME wrong.

hmm, I can do better. here's one I haven't used but for sale now http://www.halfords.com/motoring/eng...ic-ford-oil-5l

 

While folks continue to **** in each others' coffee (as always with any discussion involving motor oil), the correct answer remains:

"Run any motor oil you wish that meets the required specs published in your owners manual...."

Now back to our regular programming....

 

Great! The documentation can be found online. Go find the Product Data Sheet and let's review. Until that time, I will consider your post just what it is. Bovine scatology. And Halfords website claim is not supported by the actual Product Data Sheet. It is a clever way to sell oil that is a no-name brand from a box store. But hey, everything you read on someone's website is always true...right? Try going to Ford.

 

Nobody said that. Here's what you said:

Which prompted:

Neither one test result nor the other inherently correlates to engine life, contrary to your multiple assertions.

If the 'worst' oil in your test allows a long and happy engine life, as apparently is the case given that the oldest S-types are now in their late teens, then insisting that an oil that 'scored better' is of benefit makes no sense.

Such is the case also with promoting synthetics and semi synthetics over regular oil.

 

ASTM-97 is called the cold pour test. I stand behind what I said, as does the industry. Try again. The really sad part here Mikey, is that Jaguar recommends using the latest technologies in oils for their engine for numerous reason, and have been since they have been on the market and available to that market area. To discount Jaguar's own position, in a bias against synthetics, and then say it doesn't affect engine life, is absurd. In conclusion I couldn't care less what you place in your crankcase, however the claims you are making by reason of your bias, even against the manufacturer and their recommendations that supersedes a prior recommendation, isn't in the interest of the worldwide audience that comes to this board for solid advice. It only serves your position that "its a waste of money" when in fact synthetics outperform conventional oils in every category, and are in many cases as economical as non-synthetic. Go argue with Jaguar.

 

I see you ignored the part where I pointed out I HAVE used the kinds you allege did not exist.

Still, I suppose you just don't like people with actual experience contrary to what you post.

I guess you'll say these people lie about what they sell as well as Halfords, despite the laws here http://www.euro-oils.com/lubricants/...gine-oil-slcf/

Likewise these are also wrong? http://www.exportize.co.uk/wp-conten...etic-5W-30.pdf

I'll stick to Ashland/Mobil, BP/Castrol, Shell/Pennzoil/Quaker State thank you.

Ford 5w30 WSS-M2C 913-B Car Engine Oil

 

As I've said multiple times use what you like but looks like I proved your assertion wrong.

 

There's nothing sad here. I'd honestly appreciate you or anyone coming up with some evidence that these oils due indeed affect engine life. All I do read is lots of theory and assumption, but never any credible field results. It's been that way for the 4 decades I've been poking my nose in on the subject.

Again- If Jag issues a spec in 2016 and states that it affects all vehicles but DOES NOT issue any bulletin stating that it is retroactive- then it isn't. The spec. in force at the time the vehicle was manufactured prevails.

That's how the industry works. You should know that- if you indeed worked in it.

There are many verifiable stories of lubricants (engine oil/ZDDP levels, GL4 and GL5 diff and trans lubricants, etc.) shown NOT to be backwards compatible.

There's no stories that I can find where the use of today's oils being any better (field results) than what was available when the car was manufactured.

That says something.

 

How about you contact Jaguar before making such assertions to their recommendations, rather than asserting you're Jaguar.
