The data offered below is from my '99 Gord Explorer 4.0 SOHC using Amsoil Bypass filtration and Amsoil Series 2000 0W30 The mileage on this oil sample is 19,848 iles.
No filters were changed and no make up oil added at this sampling.
The UOA on this sample, as well as all the others, was performed by Blackstone Labs
The first ( of 5 ) column represents the virgin oil ( VOA ), the second is a previous sample of this oil ( at 5120 miles ), the third is a previous sample at 7679 miles, the fourth is the current sample and the last represents Blackstone’s average of data collected for this type motor.

Blackstone's comments: AL: Wow, almost 20,000 miles on this oil and your wear still looks good. The thing about long oil changes is, not all engines can handle them. If your engine makes a lot of metal, it builds up and causes abrasion, which wears down parts. But your Explorer is handling the long oil changes like a champ, and we see no reason to stop at 19,848 miles. The oil is still in place so we suggest running another 4000-5000 miles and then checking back to see where things stand. The TBN read 2.3, so the oil still has active additive in it. The viscosity is a bit thick. Check back.
