38,591 mi. on motor. I just got my report back from Blackstone & it wasn't good @ all. 9,600 mi. on the oil & it said lots of soot in the oil. How does one get soot in the oil? It also said lots of components that meant bearing wear. I'm using Amsoil 15-40 Syn. w/Amsoil filter. I wasn't ready to change the oil so I let it high idle for about 5 min. & then took the sample. Could this be the problem? They told me to change the oil @ 5K mi. intervals. I'm supposed to ba able to go alot longer w/the Amsoil syn. Lots of lubrication left but lots of soot & bearing wear. What do yall think? TIA

 

You'd have to change oil every week to keep it from getting sooty black. . . .unless someone is out there telling you your in deep doodoo, I would not worry about the soot just keep changing that oiul when the manual tells you to.

My oil goes black not long after each oil change.

 

Sorry but soot that shows up in a sample of the oil is a problem.

LFD, they should have had some recommendations for you in the text part of the report. I would change the filter add new oil and send in another sample in 3K. In the meantime, run the Smarty on level 1 and stay out of the fuel. I have a fumoto valve on my pan. When I sample mine I let it drain a little and then shut the valve, put my bottle under there, open the valve and fill the bottle then close the valve remove the bottle and then reopen and let the rest drain. You could always call them and ask them a few questions. They are knowledgeable enough to answer most anything.

 

smarty + quad = soot. piston rings are not a 100% seal

 

Right Diesel Doc. The advanced injectiontiming is tough on metal components. Cyl wear, bearing wear, generally accelerate. The new engines are able to extend oil intervals because they have stock pressures and do not soot up the oil as old engines did. More HP than stock equals more oil contimination and engine wear. JMHO

 

I get my OA through NAPA and the test results show Soot as a %Weight. My truck is stock so my results are what I take to be low as there have been no recommendations to change sooner or to a different oil. I am running Valvoline Premium Blue and with 6739 miles on the oil it only read 0.6 %Weight for Soot/Solids for my last analysis.

 

The CR engines have retarded timing for emissions reasons. That's why for the less soot. Increasing the timing to what it really should be isn't going to hurt anything.

Let's not forget there is soot in the oil then there is enough soot to cause concern on a oil sample. That's a lot of soot. Plus the OP stated that he has metalics at a level that indicate bearing wear, etc. I would be a little more careful in how I took the next couple of samples and ask a lot of questions.

My truck ran 607 HP the last time I dyno'd and that was with an HTB2. Now I have the HTT 62/71/13ss and a different IC. I haven't dyno'd it yet but have run it for over a year and did a sample with 9k on it. I posted my results before but they said other than a slightly high viscosity my report was perfect.

 

My report syas this: Iron/93, copper/15, lead/6, pottasium/21ppm(maybe antifreeze but I have used very little), insolubles/SOOT, TBN/5.6 & alot of other good values. They were also comparing this to a 6,700 mi. test data bank for my type oil.

 

You should post your uoa...

if soot is a problem, then one of the best oils out there for that would be Delvac 1. Delvac 1 is known to allow for up to 3% soot and still maintain supreme engine protection. The downside? Cost.

 

I tried & I can't figure out how.
