synthetic oil for 06 Sonata V-6

That's not a real good example. Alot of Bose products ARE now made in china.
That gets us back to the "what's the label say" issue.

I've been running Supertech Synthetic for a long time in a Dodge Caravan,
Chevy Malibu, and Chrysler T&C with no problems - no leaks, no sludge, no
nothing! If you look down under the valve cover on these vehicles, it looks
really clean.

 

I quoted the fact. That fact is that all oils aren't created equal and
some are better than others. You and Mr. Supertech are now asking me to
post the details of the article, which would require scanning and
posting as most was in graphical form. That would clearly be a
copyright violation. And I'm not doing that much work (assuming I even
still have the magazine in my archives) to save you $7 or whatever it
would cost for a reprint.

I'm done with you.

The specs aren't even close though. I was talking brands, not origin.
What part of "no-name brands" above wasn't clear?

Great! I'd now try running re-refined oil or maybe even reusing someone
else's oil. You'd save a few more bucks.

Consumer Reports, eh? I guess you must have conveniently forgotten this
article that refutes everything you've suggested:

http://www.xs11.com/stories/croil96.htm

Granted, it's ten years old, but at least it's an actual controlled
test. Read it and weep, Matt.

 

What have we here? Could it be yet another feeble attempt to divert the
discussion and confuse the issue we've been debating? Imagine that!

BANG! You just shot yourself in the foot again, Matt. ;-)

 

This is all true, but what's your point? It says nothing specific about
the companies we're discussing. Unless you know what their QA/QC
procedures are, you have no right to denegrate them based on pure
speculation.

 

I emailed you a .jpg file, Matt. You can't do the same for us? Tsk, tsk.
I guess it's just easier to get your panties all in a wad and refuse to
participate.

BTW, I have no ax to grind for Supertech, per se. I just don't like
seeing a good product being lambasted by someone who obviously has no
clue what they're talking about.

As I suggested above, go read the Consumer Reports article, since you're
a fan of their testing. In case you ignored it above, here's the URL again:

http://www.xs11.com/stories/croil96.htm

If you're too lazy to even click on the link and read the article - or
unwilling to do so, since it refutes your claims - I'll summarize their
conclusions for you:

1- There was no measureable difference in wear in the engines tested
between brands of oil, regardless of price or type of oil (natural,
synthetic or synthetic blend).

2- Any API certified oil will protect an engine for typical 7500 mile
change intervals.

That was as of 1996. API standards have been raised 5 times since then,
so current oils are even better than those tested, at least incrementally.

 

Indeed. If anyone expected to find serious differences among oils, believe
me, Consumer Reports would be running these tests every year.

Not surprised at all! Your training shows in your clear logic!

I had a wonderful career in QA, but sometimes it's a lonely job.

 

3 different companies. An appliance manufacturer, a pipe fitting company
that made exotic alloy nuclear fittings, and a precision tool company that
manufactured and used many bearings of many types. I was considered their
in-house "expert" on bearings and lubricants. That Consumer Reports article
read like many of my own reports, and brought back memories! We used to do
bearing and lubricant wear tests with gages that had a resolution of
..000002" (2 millionth's of an inch)

HA!! That was my philosophy way before it was widely adopted! I was
considered a radical at 1 time. Instead of hiring and maintaining a huge QC
department to weed out defects, I emphasized quality at the point of
manufacture. I wanted every machinist to be a QC technician. I wanted my
inspectors, techs, and engineers to be primarily teachers. And yes, 6 Sigma
was nirvana!

Exactly!

 

Well, I suppose the processes are so standardized that data from 2000 is
100% relevant. But I agree that MC's and cars are apples and oranges.

 

You are right! I think everyone agrees with you on that.

But Matt, it's a matter of DEGREE. Some of us believe the differences in
modern premium oil are so miniscule that it's insignificant. Apparently you
believe there are large enough differences within groups of similarly rated
oil to cause premature engine wear. Even if that were true, I don't believe
it would lead to the death of the engine. There are many other things that
will happen to it first.

I dropped by friend's house 1 day, and he was struggling with a pallet of
bottled water he had just brought home from Sam's Club. I ask about the
water, and he said he "didn't trust the city water". On top of the pallet of
bottles was several cartons of cigarettes. I told him not to worry, and
guaranteed him the city water would not kill him!

 

These were laboratory tests of a half dozen or so oil properties of oils
both sold as being for motorcycles specifically and standard auto oils.
They weren't tests in engines so the fact that the tests were
commissioned at an independent laboratory by a motorcycle magazine isn't
relevant.

[original post is likely clipped to save bandwidth]

I never claimed all oils are the same. I didn't even enter this thread
until you fabricated copyright law as an excuse you couldn't provide data!

If you expressed opinion based upon prior readings or other sources, no
one could argue. Anybody can have any opinion.

I do have the opinion that synthetic's benefits are often over stated
versus high quality modern conventional oil. "Overstated" does not mean
they are not superior in some applications!

I have owned vehicles since 1966 and never used synthetic. I never had an
oil related engine failure and probably have an average of 140,000 miles
per car before replacement. I always used brand name oil of the highest
rating available at the time.

Perhaps it is the brand motor vehicle I preferred or perhaps it was proper
care. Since any oil is vulnerable to contaminants and additive
deterioration, every oil needs to be changed.

Thus I am left with no data to suggest why I should not just meet or
exceed the published specifications for my 2006 Sonata V6.

Agreed.

Again, we get back to degrees. How bad were the bad ones, and how were the
tests quantified?

 

It has been 5+ years since I read the articles. I don't remember the
specific details and I don't think I even have the mags anymore. Since
nobody here cares enough about the data to obtain it, I've got nothing
more to say on the subject.

Actually, I hope that the folks here don't buy premium oils such as
Mobil 1, Castrol products, and similar. They cost too much now and if
the demand gets any higher the price will only increase and cost me more
money! It is bad enough that makers of cars such as the Corvette, a
model or two of Porsche, etc., ship Mobil 1 from the factory and pretty
much require its use.

Then again, Hyundais are cheap cars so it seems fitting to use cheap
oils, oil filters, tires, etc., on them.

Oh come on Matt. I've worked in Corporate America for over 25 years myself.
That fact has nothing at all to do with the discussion at hand. Do you
think that most of America would really be surprised by things you've seen?
The truth is that most of these "hidden corporate secrets" are quite common
knowledge.

That's not what was stated Matt. Red Herring.
Uncertainty and Doubt. Most times, > Totally unfounded and only intended
to smear a competitor or a

No, FUD is almost always unfounded and intended to smear. Factual issues
are one thing, but speculative fears based on no evidence are not factual.

 

Ok - I'll be the one to steer this thread in a different direction...

I've never used synthetic oils. Pure dino all the way. I've typically
driven my cars for 200,000 - 250,000 miles. I've had the valve covers off
more than one of my cars and with well over 100,000 miles, I've never found
any sludge or buildup. The most recent experience of this nature was when I
replaced the intake gaskets on my daughter's '98 Malibu with a 3.4L. The
car had 118,000 miles on it and when I pulled the valve covers the thing was
spotless. On nothing but dino oil and those crummy Fram filters that have
such a bad reputation here. The dino oil came from Wally World - you
guessed it - SuperTech.

Someone has been bringing up the word "degree". I think that is the most
appropriate word to this whole thread. Any differences are really not that
significant. I change my oil faithfully at 4,000 miles and always have.
I'm switching to synthetic just to get the added mileage between changes.
I've got 5 cars in this household to tend to and reducing oil changes
appeals to me. But, do I expect something more or something better from
synthetics? Nope. How do you improve upon the experiences I've had in 35
years of driving and maintaining my vehicles?

 

I certainly hope so.

Yeah, tell me about it. ;-)

 

Those longer intervals appeal to me too!

I think I would use synthetic oil if I didn't worry about the filter. I
trust syn oil up to 10,000 miles, but I only trust oil filters up to 6000.
Filters are so small these days I'm afraid they could become restricted by
normal combustion products.
