Bad News from Blackstone

[SnowDrifter]

Used Harley technique of just poking a hole in the top of the filter and letting it drain to get enough oil for the sample and to mitigate the mess in removing the filter.

Poor collection technique. Oil flows around the outside of the filter, through the media, then back up through the center. When you poke a hole in the bottom, the oil flows out of the center (from the block) and basically back-washes the filter media, rinsing any captured contaminants out with it.

The appropriate method would be to clean around the drain plug, remove it, let it drain for a few seconds, then place your container under the stream until full.

I'd send another sample in. Unfortunately, can't really say anything about this one because of how it was collected. It's a meaningless result.

I asked for advise, so I'd better listen to it. Just now emailed Blackstone asking them to disregard my most recent sample. I'll pull another one in a few days and get it off to them at that time.

Yessir, you need to follow their recommended method of obtaining a test sample or it’s worthless because their test is based on that method.

I've never done an oil analysis on any vehicle I've owned. I guess I'm missing out on a whole lot of worrying.... Lol

Try grabbing a copy Royal and dumping it through a coffee filter see if you have anything in there left when you're done. Certainly don't need to pay somebody to or $300 to sniff your oil good luck

Who’s charging $300...?!? IIRC it’s around $28 for a full analysis, shipped..

Holy crap what side of the world did you wake up on? Pour your oil through a coffee filter? This ain’t the jungles of Bolivia, we have tools here that can measure parts per million, can a coffee filter do that? And it only costs about $25. $300 will get you a blowie to go with it.
