That's a lot of trash in the filter. Is this normal? Seems to be some pretty contaminated fuel.

20 amps at 240v is 40 amps at 120v, so it's capable of delivering a lot more power than your normal 15 amp 120v outlet.

There is so little variation in your data that it isn't significant. We have no way to know how much lab error is in your data, so there is no way to account for it and there is lab error. No UOA data is 100% accurate. The average Fe is 1.62 so 2.06 is only 0.44 ppm/1k miles above the...

I have only seen drill bits break, not bend. Your bent bit probably was not hardened correctly.

The orientation tag in the exif data from your camera/phone is telling the browser how to display the image. If you rotate the image and save it the orientation tag will be changed and it will display correctly.

Listen closely to what @Kestas says. He is a career metallurgist that decades of experience doing failure analysis.

I would give your scenario a 0% chance of happening unintentionally.

Frankly, the cams all look like they are junk. Lots of pitting and scoring. I guess it depends on what life you expect out of the engine. If it's a short term engine that is going to the boneyard, then run it. If you expect a long life then junk the cams. However, I'd want to completely go...

You mean, "Oh, I didn't realize I was shutting the fuel off to the engines"?

You have a good baseline for the next sample.

Iron of roughly 1 ppm/1k miles is very good and the other metals are far lower. Metals are of no concern. There were two quarts of make-up oil, which somewhat replenished the additives. Oxidation of 14 is medium if you consider 25 a condemnation limit. Zero concern with this oil change...

I met a B1B pilot that said the highest fuel flow he ever saw was a sea-level with full AB which was 398,000 lb/hr. That's 60,000 gallon/hr.
