For N9KB:
Ken,
It was really "lube engineering". I never did understand why
it was called "tribology". The course designers may have
thought it deserved a more "sophisticated" name since it was
a graduate-level course.
My oil consumption experience with light trucks/cars has
been about the same as yours - but a different matter with
my motorhome engines (GM "403' and "454" and a Ford "460").
'Bought the motorhomes with the "460" new and the "403" with
24k mi. I use dino 15w40 in the "403" and "454" (latter used
only summers in Alaska). My son uses same in the "460"
('gave that Mh to him/his family years ago when we bought
the GMCMh).
'No challenge to your experience with your "455". 'Just wish
I could replicate it. It may very well be that the Olds
"455" has a better oil control design than of engines in my
motorhomes...
'Don't have (or really want) an aircraft. 'Spend a
disproportionate part of my time taking care of the stuff I
already have...
Thanks for the exchange...

Hi Fred.
Quit using those big words that I do not understand.
TRIBOLOGY???
I am just reporting my oil consumption as it is. My cars
are all the same way and I do not drive new cars. My 98
Blazer has around 170,000 on it, Laurie's 99 Jimmy has
100,000 on it. My daughters 96 Blazer has 280,000 on it and
my 05 Colorado has around 80,000 on it. None of these use
oil.
I believe if you use the proper weight high detergent oil
with a decent filter and change it based on miles or
annually, you should not have major engine wear problems.
The only engine I have ever had problems with was a 2.8
liter V-6 in an S-10 that I ran Mobil 1 in since new. I
wore a timing chain and gear to the point I had to change it
at 40,000 and I had lifter problems starting at around
65,000 miles. GM refused the warranty clain based on the
MObil 1 use. (Their warranty was only 36,000 and ther
refused an special claim on this.) In 1991 I dumped that
vehicle and bought another new one identical to it. This
was the last new car I ever bought. I ran that 1991 truck
until last year on Haveline 5w30 winter and 10w30 summer. I
finally got rid of it because everything was badly rusted
out. The fellow I sold it to wanted the 170,000 mile engine
to put into another S-10. It also used no oil.
I run Havoline in my newer engines because Rotella does not
make a 5w30 or 10W30 oil. I run Rotella dino 15w40 in my
older looser tolerance gas engines and in my diesel tractor.
I also run a 180 degree thermostat and an external oil
cooler to keep the engine oil a little cooler. This keeps
the oil is a little thicker. The 180 thermostat and trans
oil cooler also helps the trans which is bolted directly to
the engine run a little cooler. Dick Paterson recommends
the 180 thermostat for the same reasons. Dick also made a
comment in one of his seminars that I attended that he
noticed reduced oil consumption when he switched to Rotella
form Mobil 1 a few years back. He had no explanation for
this.
That is my experience. What can I say?
Now if you want to talk about oil burners, lets talk about
my airplane engine. I would be happy with 1000 miles to
the quart on it. That is why we use ashless dispersant oil
in an airplane. 1000 to 1200 miles on a quart is
considered about the best you can get on an air cooled
loosely built airplane engine. Note: We actually measure
oil consumption in hours rather than miles on an airplane.

Fred,
We actually had two separate courses. One was tribology - which close-coupled to the fluid dynamics section. Tribology being the study of things that rub one on the other. The second was lubrication technologies and between the two were included all manner of slimy and sliding things and hydraulic wedges and journal orbits and dynamic film displacement and other whole sections on dry film lubrication with metallic soap like Graphite and MoS2 and then low viscosity support like air bearings. It's no friggin" wonder that program is dead.

Tribology
From Wikipedia, the free encyclopedia
Tribology is the science and technology of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. The word 'tribology' derives from the Greek root τριβ- of the verb τρίβω - tribo "Ι rub", and the suffix -logy.
Applications
The study of tribology is commonly applied in bearing design but extends into almost all other aspects of modern technology, even to such unlikely areas as hair conditioners and cosmetics such as lipstick, powders and lipgloss. ...

WOW. All of this because I decided to give Fred a hard time. I think, or at least hope, Fred knows I was just joking around with him.
Tribology is a new word for me. I never had that word in EE or physics class 45 years ago and my spell checker hates it. .

My rule:
If you are offended by something you read here on GMCnet, you probably read it wrong.

I know Fred first hand from GMCMI and I was just teasing him a little bit in my response. I'm sure he took it that way.

Don't be feelin' like no Lone Ranger here guy. We had the course in 1968, and I did not hear the word again (unless I used it and then the other engineers would look at me like I made it up) until 1986 when a client came into the lab and wanted to do a lubrication study. When he used the word, everybody said "go find Matt".
