There is no requirement from Jag that the oil be synthetic or semi-synthetic. Factory fill on S-types was non-synthetic.

Given the conservative oil change of 10K miles or 16K KM, it's waste of money to use synthetic.

 

I did- as did several others. The number of events where lubrication MIGHT be the cause is insignificant given the size of the fleet. To suggest that a 'better' oil MIGHT have avoided or delayed the event is without evidence.

The leading causes of engine death on S-types is overheating and cam chain tensioner. Aside from collision and corrosion, the leading cause for vehicles being retired is electrical/mechanical failure unrelated to engine issues named above.

As always, if spending your grandkid's inheritance on boutique oils makes you feel better, go for it.

I'm spending mine on which ever beer brand has the best commercials. Apparently, if you drink enough, you get invited to the best parties with the hottest super models. I'm here ladies- gimme a call!

 

Jaguar doc JJM 10 34 99 501 states oil needs to meet API SJ, ACEA A1 or A3, and Ford WSS-M2C913-B preferred. Oils that meet these criteria are full synthetics. I can pick up a 5 quart jug at WalMart for $27.

 

But not all oils that meets (and exceed) those specs are synthetic- like the factory fill.

 

Go to Castrol and find anything BUT fully synthetic EDGE 5w-30 A3/B4 that meets those specs. Post it back here.

Go to Ford and find any oil they have that meets WSS-M2C913-B that isn't fully synthetic. Post it back here.

BTW, WSS-M2C913-B was Fords spec first of the fully synthetic 5w30.

 

Sure-right after you actually read the documents you reference and discover that the spec you mention is not applicable in North America. Cars here (as also mentioned in the owners manual) state only " API SL and ILSAC GF–3".

 

Now you're simply being argumentive.

Jaguar and Castrol Partnership - Co-engineering Quality Oil

Jaguar exclusively recommends Castrol EDGE Professional oil, (fully synthetic) engineered to perfectly complement our engines and optimise performance. Castrol EDGE Professional is stocked by Jaguar dealers.

The OP asked for a recommendation other than Castrol. One of those candidates is Shell/Pennzoil Ultra Platinum.

 

That's nice. My local bar recommends Labatt beer cause that's who they've partnered with. Still no phone call from the super models.

Have you run out of straws to grab at?

 

Have fun peeing on the electric fence for yourself....

 

Ah- thanks for the suggestion but unlike any of your points about oil, there's plenty of first person evidence demonstrating that mixing water with electricity is not a good idea.

 

I've yet to see you post a single conventional or semi-synth to support your claim "But not all oils that meets (and exceed) those specs are synthetic" as it relates to ACEA A1 or A3, or Ford WSS-M2C913-B. You can start there.

 

My comment: What exactly is an oil-related failure? Maybe engine death after 100k miles when others go for 200k miles. Maybe the need for rebuild after too much smoke. Did anyone ever suggest that those things were oil-related?

What a joke! I have never seen any such suggestion from you - to the contrary, all you ever seem to say is "your engine couldn't care less".

Can't understand why you would discount Box's industrial experience, especially as I recall you saying that most of the research on lubrication is done by engine manufacturers, not by oil companies.

 

This is getting good. Continue, please...

 

What experience? Quoting lab results and advertising spin counts for very little with no field results to correlate.

Correct- which is my background. Despite four decades of looking, little or no field evidence has surfaced supporting (to address the specific subject at hand) the need or benefit of oils beyond the OEM's spec. Even the BITOG guys have come up dry.

Should I switch to Molson? There was a model in an advert on TV last night that gave me a special look. It was just for me, I'm sure.

 

Ford WSS-M2C913-B is the spec for fully synthetic 5w-30 stock. Period. There is no conventional, nor semi-synth that meets it. Period. Ford WSS-M2C913-A was for semi-synthetic. Jaguar was recommending this specification for full synthetic well over a decade ago, and documented. There is no debate. Your dismissal of this fact, is simply because you have taken a position, and feel an incessant need to be right.

In the end, I couldn't care less what you choose to use in your vehicles. However, the position you are taking here, is rather uninformed.

 

Doesn't apply to S-types in North America. Go check your owner's manual or JJM 10 34 99 501.

End of discussion. Have a nice day.

 

Jaguar's own website, which I left a link to, speaks to their current recommendation for ALL Jaguar petrol engines, regardless of year or model.

For those who want to find a suitable, well engineered non-boutique oil, that won't break the bank, and choose something other than Jaguars dealer-only choice, I still stand by my recommendation from one of the largest, if not the largest, refiners worldwide. Their engineering department is infinitely more experienced in it than you. Other manufacturers also recommend it. Racing teams prove it daily.

End of discussion, and have a great day.

 

I just Googled the oil spec and if came up with shed loads of synthetic oils to choose from. No semi synthetic or mineral oils.
But the beauty of online shopping is you don't have to pay main dealer prices at online motor factors for good branded stuff.
7 litres B spec @ £32 + vat best price so far.

 

... therefore, out of ten single malt Scotch Whiskies that meet the
legal requirements for that appellation, there should be no discernible
difference. Indeed, moonshine would do as well since it is also a
grain based alcohol.

The single malt afficianodos posting to this thread will have an
aneurism, but it clearly follows their particular line of reasoning.

Personally, single malts give me a headache.

As for oil, I like the premise of Pennzoil Ultra Platinum, I just cannot get it
in my preferred weights so I'm settling for 0W40 Castrol Euro on the upcoming
change. Wish is wasn't a 0W though.

No, I absolutely refuse to use 0W10 Regular Grade Ethanol no matter what anyone posts.

That's an old tired strategy. How about you post a link to the contrary?
