for the guys that are into recreational oil changing...

I don't agree with Tegger very often, but here I agree. This sounds like ill
thought out jibberish.

 

Severe conditions are defined as follows:

- Driving less than 5 miles per trip or less than 10 miles per trip in
freezing temperatures.
- Driving in extreme hot (over 90F) conditions.
- Extensive idling or long periods of stop-and-go driving.
- Driving in muddy, dusty, de-iced, or mountain roads.

I believe they apply to most drivers in this country. Are you saying no?

 

Shush. I want "Obveeus" to answer my question according to his own
definition. That definition will surely be different from the dictionary
one, which is why I want him to define it himself.

 

Try reading it slowly - it isn't that complicated.

Well you seem to decipher some of it just fine. The age of the oil isn't going
to prevent a leak if that is what your thinking was said.
The point was the age of the oil can make a difference in some situations.
A fairly small amount of glycol added to dirty oil can do damage where that
same amount added to engine with fresh oil can avoid the damage. One of the
consequences of adding the small amount of antifreeze is that it will rob from
the dispersants and detergents their power to hold fine particles in
suspension. That won't matter as much if the oil is not very saturated with
fine particles.

The point is it is inaccurate to say there is zero risk to storing the fine
particles suspended in the oil. You can if you want debate how small the risk
is.

Try writing more clearly. I don't care to wade repeatedly through lousy
writing; I have to do enough of that at work.

 

Causes of Car Paint Peeling

There are normally three layers of coatings on a modern automobile:
primer, paint, and the clear coat. The primer acts as a base layer for
the paint, assisting with adhesion, provides a predictable surface for
coating, and provides additional protection for the underlying metal.
The paint is the color coat. The clear coat provides a hard "shell"
that protects the paint from oxidization, minor scratches, and
increases the longevity of the aesthetic benefits of the colored
paint. Car paint peeling (delamination) occurs when one or more of
these layers lose adhesion with the surface under it. Primer may lose
adhesion to the bare metal, paint may lose adhesion to the primer, and
the clear coat can lose adhesion to the paint. When this happens,
large sections or flakes of paint can slough off the vehicle.

There are two primary causes for car paint peeling. The first, and
most often associated with large-scale paint delamination, is the
improper preparation of the painted surface. All three major domestic
manufacturers have had paint problems in the late-1980's through the
mid-1990's due to changes in painting processes which resulted in the
failure of either the primer, paint, or clear coat.

The second most common cause of paint delamination happens when the
seal of the clear coat, paint, or primer get compromised by a chip or
scratch. Once the barrier has been compromised, moisture and other
contaminants can begin working their way under the coatings and create
a starting point for delamination. There are reported instances where
a small chip in the clear coat has caused catastrophic adhesion loss
to the clear coat when the vehicle was pressure washed. The
pressurized water gets under the coating and quite literally blows off
hard, brittle shell of the clear coat. However, this scale of clear
coat failure due to a chip is rare, and is indicative of other quality
issues with the paint.

 

No. Not anyone. Just shitbags like you with your attitude. And I have
never been one of the most helpful people here. Nor did I claim to be
one of those folks. But I have been here for years. Your reading
comprehension seems to be on a level with your reasoning abilities. Shame.

Looks like you've defined what camp you're in. The ignorant, unhelpful
whiners who have only negative to offer, but offer it freely.

Carry on.

And **** you, shitbag.

I'm one of those guys who believes in 3000 mile intervals because it
has always worked for me. Do I care if no one agrees with me, NO. Do
I care if I can extend it to 5000 or more miles, NO. Do I claim my
way is the only correct way, NO. In other words, you do what works
for you and I'll do the same.

 

OK, you're one of those wackos who REGRETS that he washes AND SEALS his
car (gee, takes ONLY three hours) ONLY every couple of weeks now.

That implies that you're down from your original schedule, which was
MORE than every couple of weeks.

Then you blast others for wasting resources?

The amount of water YOU waste, and the dangerous chemicals YOU introduce
into the environment (yeah, your waxes and sealears), aren't on your
horizon? Or do you CONVENIENTLY choose to IGNORE your waste while
blasting OTHERS for "waste" and introducing things that are "harmful to
the environment" that YOU don't like?

Really? Is that how you live your life? Do as I say, not as I do?

 

defined by whom?

i googled for those definitions, and guess what - they all came up on
iffy-lube type websites selling you 3000 mile oil changes.

bottom line - it's analysis that trumps all cant, sales, superstition or
hysteria on this subject. if the analysis says you can run your oil
longer, and per my original post, most people can, that's the end of the
story.

yes, i'm saying no. it's illogical nonsense.

 

yeah, on iffy-lube websites trying to get you to go into their shop and
out of your wallet every 3000 miles.

nonsense.

 

i keep garlic in my refrigerator because it stops elephants from
standing in the butter. because it has always worked for me.

superstitious nonsense - you have absolutely zero basis in fact.

 

Did that statement really need to read as: 'Exposure to all the *harmful*
chemicals also causes many health problems.' for you to understand it?

 

1. you should cite your source.

http://www.autotropolis.com/wiki/index.php?title=Car_Paint_Peeling

2. who actually wrote that? i'm a materials guy, and while i'm not a
polymers specialist, i know enough about them to say with certainty:

a. manufacturers know enough about the paints and sealers they put on
their cars, and test them enough in accelerated u.v., heat, cold, etc.,
to know whether they're going to peel or not. peeling paint is bad for
business, so they use materials that, in the normal environment, do not.
paints have been with us a looooong time. people generally learn as
they go along.

b. the above does NOT apply when a completely unknowable spectrum of
aftermarket chemicals, solvents and abrasives are applied.

again, before quoting over-simplistic attempts to explain, apply a
little logic. on vehicles with high tops that owners do not wax and
polish, have you ever seen one of those peel? what is the explanation?

 

It is an 'if, then' statement and as such, you must understand that it is
not 'nonsense'. The 'if' part may be false, though, rendering the
conclusion useless. I think we agree that, the claim that people need to
change their oil every 3,000 miles or on some time interval is nonsense
promoted by auto repair people.

 

FACT: De-ionized salt works just as well.

He didn't claim any basis in fact.

 

He made several casual observations. I wonder which one of those statements
rang true and got you so bent out of shape. I'm guessing this one:

"Some people want to feel superior, or it could be they want
reinforcement of their own beliefs, because they are not sure
of those beliefs."

 

I disagree that it is nonsense. In my 1984 AMC Eagle, those frequent oil
changes were needed. In my 2008 Ford Focus, a longer interval is needed.

The 3000 mi interval was based on good info. However, now it is based on
greed.

Good info based upon old technology (oil from 25 years ago and car
manufacturing from 25 years ago). Even without the 'greed' factor, the
technology has changed enough that the old rules simply should not apply.

....and for the people driving the 25+ year old cars, the 'topping off what
leaks out method' probably is as good as doing oil changes (though the
filter probably still needs to get changed).
