Lead spikes every other OCI. Until those come down I’ve been following the Blackstone recommendations of no more than 9K. Based on this last one it looks like they now are ok pushing it to 10-11K.

Oil was changed at the time of the sample. For the blackstone questions below. Does the user this engine sees change significantly from sample to sample? No. Daily driver for the wife. Maybe more highway trips during the holiday season (Nov / Dec), but nothing else I can think of. Hopefully...

This was the first run on Amsoil ATF after switching from the GM Auto-Trak II fluid. I'm not sure how to explain the really high insolubles or copper? Fluid was replaced with another fill of Amsoil ATF at the time of this sample. Make/Model: GM Transfer Case (Rebuilt) Vehicle: 2004 Chevy Tahoe...

Will likely extend the next run to 55K based on Blackstone's recommendations. Overall looks like things are getting much better since we bought this one. Make/Model: GM Differential Vehicle: 2004 Chevrolet Tahoe Code: OIL SVG 75w90 SVG 75w90 SVG 75w90 Unknown MILES IN USE...

Considering si hasn't changed with 4 different filter brands, and completely replacing the air intake system, I don't think that's where it would be coming from. Any other suggestions where it could be getting in at?

Yes, this is the flex fuel motor. Have not run E85 since owning the vehicle (bought at 119K miles)

I can assure you it's not the air filter. I've replaced the stock air box, tried K&N, Wix, and Amsoil air filters. And on this most recent I replaced the MAF and installed a specter cold air intake which replaces all OEM tubing up to the throttle body. I really expected to see a big reduction in...

Oil was changed at the time of sample. Cold air intake was installed at 216K miles that replaced the entire air intake assembly, including the MAF. Good news was that I haven't had any more MAF codes trip, but bad news is that it seems to have made no difference at all in silicon levels. Also...

I was thinking the same thing regarding the kit and the 2x wear, not sure why/how that could be related. Guess I'll know more after another 60K run. So far I have not had to deal with an oil leak on the Duramax, so can't really help you on that one. Pulling the cab or tranny sure doesn't sound...

Ok just found it in the manual. 50K is the OEM recommendation for transfer case fluid change.

I'm not sure on the manufacturer recommendation for service interval, I'll take a look and see what I can find. I've done 30K on past vehicles before I started doing UOA with samples. The product line is coded as ATF from Amsoil, it's their multi-vehicle transmission line...

I'll take a look at it. The problem is that it hasn't always done this, so something is quite right with the ATV. Initially when I bought it, things were fine. About a year ago it would start fine after sitting for a week, but 2 weeks would have the same behavior. It's slowly gotten worse to the...

Make/Model: Kawasaki 750 CC V-Twin Vehicle: 2005 Kawasaki Brute Force 750 Decided to send a sample in early as I had work done on the ATV to try and fix that fuel leak, plus after sitting for a week it's really hard to get started. Mechanic had to adjust valves (front cylinder was really tight)...
