If you still have the used oil, swim a magnet through it and see what you get.

I'm on the fence about how the oil looks...

If you can... Get a mechanical gage.... Its possible that you pressure sending unit isn't worth a crap.. Its the only way to know for sure

I've had a delco branded e-core crap filter drop my oil PSI by over half before, can you see if you have that "e-core" plastic cage inside your old filter?

I'm going to cut that ***** up like a trout.

I bought it and figured it shouldn't be an plastic core filter, but the only way I checked was to see it was by Duraguard. Also, thanks so much for this amazing participation. This is one of the best forums that has ever existed in the entire history of all of mankind. It'* awesome!

I'm going outside right now to run a couple of blown speakers through the oil and see what I come up with.

The blown speaker magnet I put through the oil picked up nothing. I'm going to drain the oil through a coffee filter and see if that does anything to the speaker. Long shot, but perhaps. Also, the coffee filter may show something.

So, I have good news and bad news. The good news is that I let the oil drip out over some long length of time, and then I cleaned the mating surfaces, put in the drain plug and new Purolator filter, and the new Mobil 1 oil went in. The bad news is that I have more pictures. Here we go:

Here, you can see more of the milky color the flash on the camera makes the oil have:

This is pretty much what it looks like:

While warming up my engine in 7 degrees C weather, here'* the exhaust that came out:

That may be a bit concerning because of just how white it is. The camera captured about half the colors.

Cold engine:

Slightly warmed up:

Warmed up pretty much all the way:

Some throttle on the warmed up engine this time gave me more than 40 psi on the oil pressure gauge, which is very unusual. I may have gained pressure with the oil change after 1000 miles on the last Mobil 1 and AC Delco. Is that normal?

that smoke doesnt look white. thats the blue/gray smoke that is the sign of oil burning.

or is that just the camera affecting the color?

The smoke smells a bit more strange than usual, but I'm not losing coolant, and the camera affected the color. It'* thicker and far more white.
