On a slightly related topic, my car is going in for its 3 year scheduled maintenance (at around 25K miles). I see JLR recommends a brake flush at 3 years, so I'll be doing that, along with the oil change.

 

Well there's some refreshing news. Jag has gotten with the times and now says 3 years for brake fluid. I've long suggested that the previous 2 year interval was outdated and should have been updated in the '70s when sealed master cylinders were introduced.

 

Plus, it's another thing we can debate.

 

No it isn't.

 

If we remove one small misunderstanding- its not circuitous at all. And not even a debate.

In the middle of the room we have a bear: unusually accelerated wear on timing chains. A $4k bear on the 5.0 v8- every 60k miles.

In one hand we have extensive studies from Universities- Oil companies- Car manufacturers; all saying they have discovered a new particle as exciting as the Higgs Boson particle- nanocarbon. Its incredibly abrasive and small enough to get between the chain links and cause fantastic wear. Its unique to the Direct Injection process. Cant be filtered by traditional filtration media.

On the other hand- we have nothing

We could dismiss and shutdown at the lack of something concrete or be curious.

 

Yes, it is!

 

Are you basing this on string theory or particle theory?

 

Don't get Unhingd started; he's going to have a lot of spare time in a few weeks.

 

 

Too late!

 

I spent the night in a Holiday Inn.

 

That doesn't count. It has to be a Holiday Inn Express.

 

Came in the top 300 graduates from Trump University!

 

Just had my oil changed at the dealer at 10,500 miles. This is the first oil change. I probably should have done it earlier, but I got caught-up in the Lobster Run, and put 6000+ miles on the car in 3+ weeks. Hopefully they were "good" miles. Dealer put in Castrol 5/20 Castrol Edge oil, and charged me $9.50 per quart. I guess this is not the fairly dust oil at that price, but I didn't think to ask at the time; I may call them to find out more. This was an additional oil change, not the included maintenance one, which I will do at 15,000 miles or 12 months (August) per the schedule. Also I asked how they drain the oil and he said from the sump plug; they don't suck it out. I did pull a sample of the oil to send to Blackstone and will report the findings here as another data point when I get the results.

 

Looking forward to seeing that. Thanks!

 

Aren't diamonds in essence formed from carbon under intense pressure
and heat?

Isn't diamond dust known to be an excellent abrasive to be applied
to machine tools?

No, I didn't just swallow two stupid pills. The above are rhetorical
questions.

In addition, the B4 classification found in the ACEA standards was
specifically created to address additional requirements of
Direct Injection engines.

Anyone who is interested in the specifics is welcome to go and
poke around on the interwebs. I don't have DI, and don't intend
on inheriting that mess in any engine I own.

 

To do so, you must have a reasonable expectation or belief that
it has some benefit to you even in the absence of rigourous proof that
the official JLR recommendation is deficient in some way.

There is nothing wrong with that. However, when you use
"reasonable belief" to guide your actions, it is patently
unfair to pillory other people for acting on reasonable
belief.

Just sayin'.


They are fulfilling their duty of mitigation both their shareholders
and customers. That duty of mitigation exists whether or not they
can determine a definitive solution.

It's like treating cancer.

Even when the doctor says that the particular cancer is terminal,
it doesn't seem to stop patients from taking treatment to extend
their time before the inevitable and it does not stop the doctor
from offering such treatment.

Again, mitigation in light of the consequences of not acting at
all.

 

That's always been the goal of business.

However, in the last several decades it has been completely
oriented to immediate gains to the detriment of long term
survivability.

Newer entrants to the work force have the attention span of
a fruit fly, so that's not surprising.

 

Can you see the quandary they have created for themselves in the name of Green Planet. They pushed for extended oil change to be better on the planet- then they pushed for direct-injection to be more fuel efficient. Now they have carbon nanoparticles in the air they weren't anticipating- and yes hold on to your wallets while they put a commission together to investigate its effects of that....meanwhile the much harder nanocarbon that blends with motor oil wears down timing chains responsible for keeping the emissions low. Oh the web we weave. Its as harebrained as using food to make gasoline while the world is malnourished.

 

Just had my 3rd oil change done (at 25999 miles), and they used a 3rd type of oil:
1st change: Castrol Syntec 5W-20
2nd change: Castrol Edge 5W-20
3rd change: Castrol Edge Pro 0W-20


The Castrol Edge Pro is the right stuff (they charged $15/qt), but I would have preferred 5W-20 as I store it in the winter. Maybe I'll remember to specify it next time.


[Actually, the documentation I have calls for WSS-M2C925 5W-20. If unavailable, or temps fall below -20C, use the 0W-20 STJLR.51.5122, which I think is the Castrol Edge Pro.]


Also had the brakes flushed.


Cost: this was 'B2' service.
Oil + filter, air filter, multi-point inspection: $470
Brake flush: $170
