TBN 12.4


Here we go with the report as it is......

Who actually did the analysis? Lab name?

If I am reading this correctly, you wear numbers and TBN and other oil characteristics looks fine. OTOH I don't understand "uc", and it looks like you have pretty hefty coolant intrusion "Potassium 519uc sodium 215uc" (Si at 49 as well)

Calcium doesn't look right if it's PPM.

 

[Lethal1ty17]

TBN of 12.4 is higher than a majority of brand new oils.

silicon looks high, dirt is getting in somewhere.

 

[Johnny]

I think if you cut the uc in half you will get ppm.

What kind of vehicle is this, what are the total miles on it, and how is it driven?

 

[BAD1]

The lab that did it is.

I have 42.000 mile about 70.000 kms it is a 2.0 suzuki SX4 2007

a combination of highway and city in June we did 8890kms in 8 days heavy driving on the highway short trips in the city, just over 5300 miles.

I don't know how the Silicon level is so high, I use a
EaPF Pre-Filters with a EaAU3050 shouldn't be sucking any dirt I wouldn't think.

 

[Pablo]

Silicon is coming from coolant.

 

[demarpaint]

Pressure test the cooling system to determine if the HG is bad and coolant is finding its way into the engine. If not there is something amiss with the air filter. It could be a bad connection somewhere allowing dirt into the engine. JMO

 

[Gary Allan]

For the coolant markers in the oil, not too much seems bent out of shape about it. I would expect higher double digit on most of the metals.

I would speculate (it itched) that this has to have been a recent event (coolant).

 

[chubbs1]

Are you losing coolant? Seems like the markers for a coolant leak ie. Na, K and Si. What oil(s) did you use before AMSOIL?

The column for the TBN for the new oil it says 12.5 so with that it is only .1 difference.

I drive a SX4 Suzuki 2007 42.000 miles 70.000 kms when I drive on the highway it is driven harder than I am in the city. The oil is good for 35.000 miles and I only have 7500 miles on this change.

It was high last time we had it tested 32 and I was told it was from gasket material in the engine......

But it make more sense your way.

I guess the connections where it attaches to the engine or any where along the pipe where there are clips/connections, not just where the air filter is.

It did happen before, coolant drop then it was topped up and was good till just recently, say the last month to six weeks.

Collant question answered above, as for the oil I have used Amsoil synthetic since 1600 kms which is about 1000 miles.
the oil before was what came in the car from Suzuki.

I'll leave the analysis to the experts helping you here. But wow at that TBN.

Yes everything associated with fresh air intake from the filter housing to the throttle body, including the TB gasket. It doesn't take much to allow dirty air into an engine, even with the best of filters.

 

[Pablo]

Bad1 - did the lab report have any words, anything, about coolant or antifreeze?

He means it's good.

We don't normally see a TBN that high. It makes me wonder if perhaps it's getting thrown off by the coolant contamination. Coolant contains acid nutrilizers, the aftermarket coolant additives do too. This is really what they are measuring when they measure TBN.

The potassium and sodium are high enough that this is a medium coolant contamination issue. But your wear numbers are not bad. This is good! This coolant contamination is probably coming from an issue inside this engine (i.e. head gasket). I'm assuming the calcium reading is off as a result of this as well? 7000+ calcium is out of this world! calcium silicates and calcium phosphates are used by some manufacturers in coolant, it seems that your coolant contains this. The water in the coolant will evaporate, but the other chemicals in it will not. This leaves calcium, potassium, and sodium behind. This is exactly what was found in your oil.

The "UC" designation is not meaningful, IMO. It's not a measurement. It's probably something that the lab uses to designate "unusual/critical" or something like that. The silicon is probably not an air filter problem. You said that you topped up the coolant a few weeks ago, my guess is that (if you still have the bottle it came in) if you look at ingredients listed, it will contain silicates. Some of the "universal" antifreeze types have this. If this is true, then your air filtration is probably ok, and we are back to just 1 issue -- the coolant contamination.

I would definately pressure test the system. It is a great way to detect a coolant leak. JMO

But we already know there is a coolant leak. We know it for a fact. There MUST be a coolant leak. Unless he topped up his coolant using the engine oil filler cap, there is a coolant leak. We already know the pressure test will fail. I don't mean to be overly argumentative, but we have a symptom, and we have a diagnosis that matches. We just need a treatment.

 

[demarpaint]

Then replace the head gasket! There's the solution! Lots of work too, and costly if the lab screwed up. The reason I suggested the pressure test more than once is because labs have been wrong in the past. I thought maybe someone might have read between the lines. The OP topped up coolant 6 weeks ago and said it was good last he checked. Slight chance the coolant is leaking on the outside and he's not seeing it, and again the lab could be wrong. Pressure testing is like getting a second opinion that's all.

Read some of the screwed up UOA reports and see for yourself. Pressure testing is fool proof, and if the lab is wrong it will save a ton of $$$$$$$$$$$. That TBN is high too for the amount of time the oil was in use. Could be a mistake too, lots of reasons why it might be high, no real facts though.

No argument here, just calling it like I see it. If I had to guess its a bad head gasket, but I'd be dammmmmmm sure before I started ripping into an engine.

 

[REDDOG]

Is this vehicle still under warranty?

Upon rereading your post, I read it wrong. I thought you were trying to "detect" a coolant leak, like MAYBE that was the problem. But you were trying to "confirm" a coolant leak before ripping the engine apart.

We in agreement on that!
