Blackstone Labs Oil Analysis

[AXE]

Sorry to hear this AXE. Hope you sent him a picture of the tools required and the carnage to the oil filter. That is absolutely ridiculous and no excuse. To bad you can’t take the line tech out back and have a conversation.

I've known him for 25 years and he's been good to me. They have done a lot of good work for me and they have one of the best diesel techs, who always likes working on my stuff cause it's well cared for.

I wasn't looking for a fight and I just wanted him to know about it. He apologized and said he would talk with the tech. By the time he called me back, I had gotten it off and there wasn't any damage, so we had a good laugh about it.

This was the last exchange in the folllow up for the Tahoe. I liked his response. He knows I'll give him a hard time next time I'm in there.....LOL.

We can laugh cause it wasn't ours! lol

AXE, I understand.

Got my latest test results on my 1500 and Tahoe oil samples back. Everything looks pretty good at this point. Not sure if I'll continue to do these or not. It'll be interesting if one of these turds blows!

I see the calcium is considerably higher on this oil and viscosity is lower than Mobil 1 0W40 FS. That's what some guys said on Bob's the Oil Guy website. Also see that magnesium is considerably lower.

I did a little more research and found that some formulations will run higher Boron and Calcium and low Magnesium to control ash build up. Looks like my 40 weight oil for my diesel oil analysis had similar balances, so must be something to do with the heavier oils too.

Think they will actually do an oil analysis to figure out what oil you were actually using? I highly doubt it

To get to the root of the problem, they'll drain the oil first, so there goes their evidence.

would oil collected from my oil catch can be ok for doing an analysis? or is it best if it comes from the oil pan?

Oil pan.

No, It would not be a sufficient sample. Catch can is just oil vapor collected by screens. Oil sample is best taken from the pan within the first 15 minutes of shut down for the sample to be accurate.

No, there is moisture and crap in there and it'll be a poor test result.

I've tried to go thorough the dipstick with a Pela pump, but it will not get into the pan.

If you're not doing a full change it's a PIA. However, if you warm it up a couple minutes, then unscrew the drain bolt 95% of the way. Then rock the drain plug and you can collect a sample.

thanks all. I was in a rush to get my truck to the dealer for the 6.2 recall check, but I emptied out my catch can before doing that and wondered if it would be good to test. The verdict is clearly no.
