Oil Change observation

Nice figuring, Ted, but it doesn't work that way.
In 5 or 10 seconds of running, the engine does not get to the point
there is no oil, and it does not build up any heat.
Although it is not a smart idea to run the engine without oil, the
chances he has done ANY harm to the engine are EXTREMELY remote.

The oil has not been wiped off the surfaces, and even if it has, the
extreme pressure additives in the oil are there for that purpose. Used
to be Zinc, not sure what they use now that zinc has been implicated
in catalyst failure when the engine starts to burn oil.

At idle, that engine ( the Pontiac 2.0) may well have run for several
hours before it failed.. Damage would have begun within the first
minute or so, depending on the condition of the engine, the oil that
HAD been in the engine, etc.

 

Again, what quarts - or liters???

 

USA Quarts

 

This seems to be consistent with other Chrysler vehicles. IIRC, my 3.5L
owner's manual says 5.0 U.S. quarts, but I generally need to put in a full 6
after I drain the oil and change the filter to bring the oil to the top of
the full dipstick. Our 3.8L also takes slightly over 5 US quarts,
consistent with your finding here.

That was the main point of my original post. I thought it unlikely that
3/4 qt of oil would remain in the engine. Chrysler sure seems to have a
curious practice by understating oil capacity by almost a qt.

Remember, 4.5 Canadian quarts is very close to 5.25 US.

 

WOW! Great posting. Could this be a newsgroup equivilent to "War & Peace"?


Suffice it to say WVK's hand has been thoroghly smacked and he stated that
he would discontinue this practice.

Now onto the PFTE (PTFE? - whichever - TEFLON) additive portion of this
saga - without getting into details a fleet mechanic recently told me to
"NEVER use a teflon additive to an internal combustion enigine" as a few
years ago they received a bulletin from DuPont stating that teflon was not
intended for use in an ICE. DuPont does NOT use it in any of their fleet
vehicles. Teflon is a solid and will settle into the oil film space
required the keep mulitple pieces of metal from becoming one. Additionally
it can and will restrict oil flow throughout the motor.

I know of folks who have used it with no ill effects but this is what I was
told.

 

Better yet, use TUFOIL, then you will be able to reference the Guiness Book of World
Records.

 

And you need to learn to post at the bottom rather than the top. Top
posting is for newbies and WebTV users.
