oil preference/recommendation

[Zapper]

I hate oil discussions but I will simply state this. I send samples to Blackstone and ran Mobil 1 5w20 for the first 6 or so years. Tests showed slightly higher than average copper and iron wear. I then switched to pennzoil ultra platinum 5w20 (super cheap on amazon) and subsequent tests showed iron and copper wear dropped below average. So now I buy pennzoil ultra for everything. 5 quart jug on amazon is 19.99 when on sale.

I need to do the Blackstone labs thing the next time i change my oil, i still have my old oil from when i last changed it but that is a weird concoction of atf, coolant, gear oil, 5w-30, and gasoline, so it wouldn't be worth it to send them that

That would be normal for a 2.9L

Catch an oil sample as soon as you pull the plug, easy to do with a pit. Never tried it on the ground, might need to change your angle of attack to find a good position from which to get both hands up there, pull the plug with one and grab the first oil that comes out with the other

After reading the replies on this thread, tho maybe not all, I'm wondering what's happened to the Motorcraft?

The blackstone instructions say NOT to do this. Take the sample halfway through the draining process. If you do it as soon as you open the plug you can get sediment/sludge in the sample which will ruin the test.

In my experience you cannot get it there fast enough for that, the plug must be moved out of the way before putting the sample container in its' path, allowing any sediments disturbed/released by removing the plug to be already gone.
It' may be a good idea to wipe away any excessive accumulation before even starting, with a shop rag or air hose

Actually the ones I did it on were mostly International semi tractor diesel engines that held about 5 gallons, and we pulled a sample every 15,000 mile oil change(about every 3 weeks in a truck's life) and sent it in for analysis.

Their reasoning was more tuned to the principle that the heavier particles they were looking for would be mostly metallic, settle more rapidly to the bottom(even on a warm engine), and be mostly gone any later in the draining process

How dang big is your bung hole that you cant get a sample container under there quick enough...




Their instructions not mine.

Sampling Procedures | Blackstone Laboratories

Most people take an oil sample during an oil change. Or you can do it with a quick-draw pump. Either way, instructions are below.

Unscrew bolt, move bolt, put sample container there, at least the first half pint or so has already gone flying by, taking any loose dirt with it. If they found any dirt/sand in there it wouldn't alarm them much, we didn't use that often in our engines

I was standing up straight in a 3 foot wide pit, had plenty of room in there

I work on gravel, and I believe each stone was personally sharpened by satan himself.

The best thing to do is pull the drain plug while the engine is still running and mixing the oil.

These things always made me nervous, not that I've ever heard anyone complain about them but something about just having a lever to drain the oil makes me uneasy.. I like the femco ones that have a cap, and then you screw on the hose to make the oil start draining. Still no tools required but a little more "secure".

Dammm! I never thought of that!

If your short term memory is as bad as mine is, you’d end up with a seized motor............?
