OT GM AND SYNTHETIC OIL

No traffic jams cause all you guys are down here in Florida cloggin up
MY roads <g>. eh?

I suppose so it can meet a wide range of requirements. After all, like all
products it is made to be SOLD.

And many others. But there are countless examples where a thread goes on
and on about to change the oil where it is unnecessary. They behave as if the
reason the person had an analysis done was to give the regulars there
something to say inane BS about. Get a life, I'd say.

The ones clogging up your roads are all of the old French. Look at your
beaches -- full of fat old french guys in speedos and their blimp wives
in bikinis!

We in Ontario can't afford to take time off work to do that!

Only in Quebec, (where, like most of the rest of Canada there is really
on 10 weeks of good construction weather), would they have what is
called "construction holiday" and stop all construction for 2 weeks in
the middle of July!!

Where do they get the time to actually get some work done???

French eh?

Then they are open season???

hmmmmmm...

Huw... over here... the 15w-50 and 0w-40 in Mobil1 are the only oils
stating on the label they meet ACEA A3. But the local Benz dealer
does use Valoline synthetic 5w-30. Funny... Valvoline "here" does
not mention ACEA ratings.

Turned into a confirmed bachelor / recluse, eh? Well, you ain't
gonna get more living in a place where you'll literally freeze your
nuts off! LOL

 

Not true. Delvac 1 5W-40 is their most shear stable product. But it's CH4
rated, so perhaps not always suitable for gasoline engines.

Wish I could find Delvac 1300 anywhere in southern CA .... short of
meeting Guido in a dark corner of some truck stop. Comes in 15w-40
and now 10w-30 too.

Naw, I'm happily married, with two parasites. I was just emphasizing
the point that I love it here and couldn't be lured to move.

When observing those of the female persuasion and I'm informed of some
factor that my limit my "chances" (ie, already married, plays for the
other team, etc), I just say that that reduced my chances from very slim
to absolutely zero. I have absolutely no desire to change my
"situation". I just like to think I can.

That site is sort of interesting, although I don't take the comments

Tell this to Mobil, who withdrew their AV-1 (aviation version of Mobil 1)
from the market after they had to pay millions of dollars to repair and/or
replace the Continental engines of all the aircraft owners who used AV-1.

Dan: I have never in my life inhaled air that cold, let alone

Ah, you haven't lived until you're outside in -40 weather, take a good deep
breath and feel the insides of your nose freeze.

 

What I am talking about is when the VIRGIN oil has say, 5 ppm of iron and
somebody posts an analysis that has 2 ppm with said oil and then later posts
an analysisthat shows 4 ppm for the same miles on the oil and everybody starts
posting about how terrible the second analysis is and that something is wrong.

You don't think that's stupid?

Here is waht AVWeb magaizine says:

"[AVWeb] started advising against the use of AV-1 in low-utilization
owner-flown airplanes as early as 1991. Our rationale was that 100%
synthetic oil is a superb lubricant but a lousy cleanser, and that cleansing
is extremely important in piston aircraft engines because of their loose
tolerances and the significant blow-by that can leak past the rings and
contaminate the oil."

"It's important to understand the mechanism at work here. Synthetic oil like
AV-1 is composed of long, smooth polymer molecules that don't have all the
little side branches that petroleum polymers do. This makes them extremely
slippery and gives them excellent lubricating properties. Synthetic oils
also lack the "light ends" of petroleum oils that can break down under
extreme heat and create varnish and carbon deposits.

But it's those same smooth, ultra-slippery molecules that give synthetic oil
its Achilles' heel: the inability to hold lead salts and other contaminants
in suspension. The synthetic oil molecules are simply too damned slippery to
hang onto such contaminants, so they settle out of solution and form sludge
deposits, particularly in areas of oil stagnation such as prop hubs, oil
pans, and the inside of pistons.

Tetraethyl lead is an octane enhancer used in avgas [not allowed in
automible gasoline]. It doesn't belong in the oil. Two compression rings on
each piston seal the combustion chamber and keep combustion confined to
where they belong. As long as the rings do their job well, the lead will go
out the exhaust pipe and the oil will stay relatively lead-free."

"We believe that AV-1 engines that exhibit good compression test results are
probably not at much risk of sludge formation and sludge-induced lubrication
problems. Engines that exhibit early deterioration of compression are at
greatest risk.

Turbocharged engines appear to be much more likely to be contaminated
because their higher combustion chamber pressures make blow-by more of a
problem. The Gross and Eriksson engines were both turbo'd, and every owner
we talked to in researching this article turned out to have a turbocharged
engine. Ironically, AV-1 was especially popular among owners of turbos
because of its resistance to coking under high heat."

I"m not about to deliberately test my mortality in that manner!
When it's 40 above zero, I'm bundled up and most likely indoors.
Aside from being a southern California native, look up Raynauds
syndrome.

Let AVWeb explain to me WHY ..... Mobil1 did the best job of keeping
my engine innards sparkling clean for 285,000 miles ... much cleaner
than any dino oil used in previous engines. Is AVWeb implying "100%
synthetic oil" is not the same "synthetic" (Mobil1) I put in my car
because my car engine was so clean?

 

You guys think it's taxes that keep us poor up here! The problem is
clothes! We have to be prepared for -40 C and plus 30 C!

You guys are wussies!!! |>))

Getting waaaaayyyyy OT now, I was on a plane back from Brazil with an
octogenarian British X-Pat lady. She and her husband had left Britain
after the war and set up an aerial survey firm in Brazil. Her big
obsession, all the way from Rio to Newark (talk about a come-down), was
"With similar histories, how come Canada does so well and Brazil does so
poorly?"


I replied that I thought it was the climate! If you landed at Montreal
in May, with nothing but the clothes on you back, you better quickly
figure out how to clear some land, plant a crop, build a shelter and
store you food before winter comes, because if you didn't, you didn't
have to worry about next year. In Brazil, if you didn't get any work
done today, a mango would fall from the tree to feed you. If it rains
today, it will dry out tomorrow. etc. There was no real incentive to
establish a work ethic in Brazil, like there was here in Canada. Brazil
was also conquered by "southern peoples" (Portugal) and Canada was
conquered by "northern peoples" (Britain), again with a more difficult
climate to deal with, and a stronger "incentive" to get things done.
Now, with all of the stuff that makes our life easy, a lot of the work
ethic has disappeared over the last couple of generations! But it still
lies under the surface if you scratch hard enough.

....very interesting, Dan.

I'll have to contemplate your statements for awhile <g>.

That could answer the differences in the States...too.

Minnesota and Alabama.....hummmm

Florida does not count...cause we got all the damned yankees that came
down to mess up paradise <g>.

Good observations. Do you wonder if predominantly cold climates also
incline people favor collectivist economies?

 

Not like you think. Due to the isolated situation in which French
culture developed in North America, they are about as French as a
New Jerseyite speaking Elizabethan English. (Not the current Elizabeth,
either!)
You have to go backward about 350 years to make the connection.

Be careful. Python-like, they CAN fart in your general direction!

I meant the 0w/40. Sorry.

I deal with it daily. The 0w/40 is a superior oil which stays in grade
and lasts for longer drain intervals as proven by the Standards it
meets and exceeds.

It is such a pity then that it cannot meet any of the higher standards
set for measuring this. In fact it is quite shear stable, there is no
denying it. The 0w/40 is however proven to be stable and has other
properties which allow it to be used for much extended drain intervals
which are not possible with the present chemistry of most other
viscosity grades of Mobil I.
The Standards are just that.. "Standards" which allow a comparison of
oils. Get over it and educate yourself.
