Is Redline polyol based synthetic on the VW list?

Oil Pressure Indication in DIC by desertrat5
Dec 10, 2004 (6:22 pm)
Reply
I have both a Buick Ultra and a Pontiac Bonneville SLE. The Buick forum is not very active and I have not received any feedback on the Pontiac forum which is fairly active. So I am posting my question here.
I just had a LOF and engine detail on my wife's 2000 Ultra. Now the DIC shows 129 psi oil pressure regardless of engine RPM. I have never seen it that high and I have never seen it rock solid unchanging. Is it possible that water from the engine detail has messed with a connection somewhere (all the other DIC indicators seem to be working okay)? Or could they have done something in the oil change to make the pressure that high?
My 04 Bonneville SLE has a gage which typically shows between 60 and 80 psi oil pressure. The gage does sweep from 0 to 120 back to 0 at startup before registering the actual pressure.
  
Thanks in advance for any info.

If water gets into the connection at the pressure sending unit you can get a short to ground and peg the reading low, or open and peg high. At least I think that is the way it swings. Been a while, but I saw this before on an Olds engine. Find the pressure sending unit and make sure the connection is dry and tight. The DIC can only display what it is receiving, or as we have said about computers for years ...

The other interesting item is that the DIC also says "Normal" right next to the 129 psi reading.
 
Is there a check valve in the filter that could be plugged and drive the pressure that high? I know some filters have such valves to keep the oil from all running out of the engine after shut down.

my oil change story by scottinky

I took my 03 Pathfinder to my dealer to have the oil changed yesterday. Picked it up in the afternoon, drove it home. Went out last night. Upon returning home, noticed a big puddle of oil in the garage. I didn't see it when I left, but it was there. My round trip was about 6 miles. I turn off the motor, and watch oil drip from the filter location. Crap. I pop the hood, check the stick , I have maybe 1 quart of oil left. So, I add 1/2 a quart of what I had in the garage, and pulled in. This morning, all the oil had drained out, no surprise. I call my dealer and inform them of what happened. My dealer rocks! Sure, they made a mistake, but my motor didn't blow, whew. within an hour, I had a flatbed tow truck, and a guy from the dealership at my house with cleanup supplies and a rental car. Unfortunately, i won't get my truck back till monday cuz there are no mechanics there. However, this dealer has always taken care of their customers, and I am amazed at the service. The general sales manager took it upon himself to take care of the matter. All I can do now is wait and see what the problem was.

It is entirely possible that there is more than one sending unit. If not, could be a guage failure although these days that is pretty rare. Would be a good idea to have the pressure checked to ensure what is really there. 129psi is way over the top. I doubt that is a true reading.

Trouble like that is never pleasant, but it is great to hear a story about a dealership that reacted the way yours did. Let us know what is found. I'll guess the seal on the filter was defective, or you suffered from the two-rubber-ring syndrome.

Oil changes - then and now by taft4

A friend recently gave me the owner’s manual of a 1927 Packard straight 8 (384 cu. in eng.) that was her late father-in-law’s when long ago he purchased the car new. Talk about oil changes, in those days it was really something. Thought you might be interested in seeing the details which are: (1) Remove crankcase oil drain plug and drain out old oil; (2) Replace drain plug and pour in through oil filler one gallon kerosene; (3) With ignition off turn motor over a few times by hand or with starter to clear oil lines of sediment, then drain, removing cover from under oil pump; (4) Remove oil pump screen, clean and replace; (5) Replace drain plug and cover and refill crankcase to level with fresh cylinder oil. It goes on to say the motor needs about 2 gallons of oil, and not to overfill it, but if overfilling, do not overfill by more then one gallon.
 
The instructions go on to say Packard suggests the owner use a high-grade medium gas engine cylinder oil and in the Detroit area they use oil with a cold test of under 25 degrees fahrenheit. Oil changes should be every 1000 miles in the summer and every 500 in the winter and the dealer can only charge for the oil, but the labor is free.
 
This was the warranty on the car: “The Packard Motor Car Company has warranted that for a period of ninety days from the date of delivery to the purchaser it will replace, free of charge, any part claimed within that period to be defective and found by the company to be so upon examination, provided such part is returned to the company within that period for credit or replacement. Such free replacement does not include transportation charges to and from the Packard factory, nor the cost of installing the new part. Tires, rims, batteries, speed instruments and other accessories, being subject to warranties of their respective manufacturers, are excepted from the warranty.”
 
I know this is not the focus of this board but I found the oil change information interesting, and compared to today’s situations, rather humorous.

Every 500 to 1000 miles-- that's the killer! Let's be thankful that motor oils are now much "cleaner" than back then, and that the kerosene flush is not needed.
