milky oil fill cap??????

[gsbrockman]

I highly recommend Oil Analizers Inc. Not only are they the recommended UOA company by my local Cummins they offer more data for less money than blackstone, including TBN as a standard option (very important), and they seem to have better tech's too.

I was on the blackstone wagon for a while but became very unimpressed with them over time.

Care to elaborate???

Just the fact that they throw in TBN is good enough for me to try. And they've been getting kinda snarky in the comments and communications.

It basically boiled down to lack of knowledge on the techs. The write ups were vague and a phone call was less informative than the vague write up. They didn't appear to actually know anything about oil.

The lack of TBN on the basic test is also BS. TBN is a very important number on a UOA and shouldn't be an extra fee.

It's been a long time since I used them but the comments I see when people post their UOA's don't appear to be any better.

The universal average thing is also a waste of ink. It doesn't actually tell you anything.

190 is normal unless pulling hard. I never go over 212 and that's pulling a 32,500# combined load. Blackstone IMHO is a great place to have oil sampled.

Coolant temp runs 190-195 unless hooked to a loaded trailer , 225 f was the warmest, during last trip, seems to act normal for what I see... oil sample being sent in today...

I wonder if your crankcase ventilator filter is plugged, have you changed your filter lately?

Changed my oil last night after work. If anyone should have a milky oil cap & valve cover, i should.
I dont. I even felt around along the top of the valve cover to see if i could find any milky substance.

I drive only 6 miles to work & 2.5 to get groceries. I change my oil every 4 months to combat fuel dilution. I use amsoil 15/40 OE full synthetic. It seems to attract less moisture?

After 4 months, I suspect fuel dilution because it climbs the dipstick gradually.

Have you done a UOA?

Does the dash reminder come on?

13+ engines don't have near the issues with fuel dilution and the computer OCI is pretty accurate.

Have not done an oil analysis. But it does alot of active regens. I realize the extra injection of fuel during active regens could introduce fuel dilution.

Dash minder was at 81%. But in 2 3/4 years of ownership, it only has 1 idle hour. I would guess it should be closer to 150 idle hours.

The 2013's had something wrong with their programming that was never fixed with an update or RRT. The fuel filter warning is much more accurate.

I changed it this weekend for peace of mind.
Next week, i'm taking off on a several thousand mile trip over several weeks. I wanted fresh oil.

When i get back, it will be time to change fuel filters and lube the front drive shaft.

I would do an oil analysis. It could save you quite a bit of money in oil.

Yes, I plan on doing that.

I have seen people post different ways/times/timings of taking oil samples.

I watched this video when I installed my bypass filter. https://www.youtube.com/watch?v=oAGo6jbDLOQ

And I did a lot of what this guy recommends. But I didn't put an oil sampling cock on the the system anywhere. I see people taking samples out of the oil drain plug at different times (middle of drain or end of drain).

I went back and watched this video and I found it interesting that he put the oil sample cock on the clean side of the bypass filter. This seems like it might not give the most accurate reading of the oil in the sump since his sample was just filtered.

I have the swivel oil cap that he has and if I took the sample out of the return to the valve cover, it would nice and easy to collect, but might not be the most accurate oil sample.

Any thoughts?

 

[AH64ID]

The return line to the oil cap is a great place to sample from. The data in the sample will not be effected by a filter.

Man you must like to throw away money ! You should stop looking at the color of the oil and get an oil analysis if you are worried. That will tell you how much life is left in your oil so you can stop wasting your money along with oil.
I owned 6 commercial semis over a 35 year career and changed oil at manufactures recommended interval my 89 was 15000 my last one a 2010 was 25000. That is an example as to how much the oil has improved. All the trucks had a half million miles or more when sold. Save your oil money and buy your girlfriend or wife a nice nite on the town. then you will get something for your money!

Here is the Lab Report from the Milky Oil....

Another reason I think blackstone sucks... TBN of 1.0 is not serviceable oil. Cummins only allows TBN to degrade to 50% of it's original value before the oil needs to be changed.

With only 2,000 miles on the oil the TBN is VERY low, IMHO. Something is depleting it very quickly. Delo 400 LE 15W-40 starts at 9.3 so the oil was 75% "used" in 2K miles. TBN should have been 8+ with that few of miles, IMHO.

 

[dougsram]

Looks like a very good oil sample. No water or anti-freeze and little to no fuel dilution. So, what is causing the milky oil appears to be a mystery!

 

[ramfan]

thanks for the help, I can only hope this milky ghost starts to show its self soon, time will tell...... thanks again for all the input!!!!!!!!!

 

[TFucili]

Not knocking Delo, but try a different oil at next OCI.

 

[RVTRKN]

Can you scrape a little of it off, and have it analyzed? I don't know who could analyze it, but it might be worth contacting oil testers to see if they could. I have thought about your milky substance, and back in my teen years (quite some time ago) I disassembled motors for cleaning to be rebuilt. A 327 Chevy motor had a substance like you describe, but was real heavy around the rocker arms. It was almost a gell and only the areas around moving parts were free of this gelly. I was told it's the consequence of using oil with detergent in it.
