Oil Analysis Help - X15 565/1850

Dunno why they're flagging the base number on the D4739 - less than 2.0 I'd change it, but

Rest of it looks good, fuel dilution - they must use a different test.

I use Schaffer's, so I'm more familiar with their analysis. I'm guessing CAT/Blackstone/Schaeffers have different testing.

I mainly monitor fuel dilution, bearing/metal traces, glycol, soot - and change ultimately on acidity (base).

 

Base number is highlighted as low, other than that seems ok. Do you have bypass filtration?

 

To be honest with you - I use Schaeffers oil because I like the guy. He came to my house, greeted my wife and I, was polite, and I consider him a business friend for the last 10 years.

The product gets delivered to my house free, over $500 - they have a range of lubricants, and test kits are cheap.

Is it any better than any other oil? I doubt it.

Is it overpriced? Yes, but I have it in a barrel when I need it.

Oil sampling - to a guy that owns 50 trucks, should be a no brainer.

Oil sampling - to a guy that owns one truck, should be a no brainer.

I pull a sample every 10k - I have gone to 40k before changing, or -

"OH, we have fuel dilution, lets find the problem", and saved $30k -

Or - you can just change oil regardless at 10k miles , and see what happens.

To each their own.

 

Was going to be my next question - Amsoil has a gallon spin on filter bypass unit for less than $500 - EaBP150 (or something). Recommended change at 50k miles - filtering to less than 2 micron.

Adds 10% capacity and cooling to your system, slow bypass filtration - $50 filter - why not.

 

Molybdenum is what they promote I think. It won't help with soot or fuel dilution at all. Soot needs to be filtered out, fuel dilution will come from injector issues - which is why I think the samples are cheap canaries in the coal mine.

Somebody smarter can probably tell me, but the factory filter or filters for that engine may already serve a 'bypass' function if it has two and they're different micron size.

Putting an Amsoil bypass on it certainly can't hurt.

 

How many miles/hours on sample and why 10w30

 

The ISX and X15 both use a internal bypass filter design in one.

From QSOL .......

A combination oil filter is present on the engine. The upper portion of the combination filter contains the full-flow Stratapore filter element, while the lower portion contains the full-flow NanoNet element.

The combination filter design has been optimized to distribute oil flow during normal engine operation; however, during extreme engine oil conditions (additive dropout, contamination, soot etc.) the improvements increase the overall filtration effectiveness.

Oil circulates through the Stratapore full-flow portion of the filter, into the oil cooler housing, and is directed to the engine oil rifles.

A smaller portion of the oil circulates through the lower NanoNet full-flow portion of the filter and is directed to the engine oil rifles.

End QSOL-

If both sections of the filter become clogged a external bypass valve in the filter head opens to supply the engine with oil by bypassing the filter fully.
