Originally posted by Baveux: That's what he told me "I have discussed your requirements with a diagnostician and the recommendation is that you opt for a Mob2 kit but request a TAN instead of a TBN in view of the fact that you will be monitoring the oil from gasoline engines" Any better ?
quote:Normal and abnormal wear can be effectively traced by monitoring wear metal levels at each drain. TAN by itself is of limited value in determining oil condition of an engine oil .
Originally posted by Baveux: But what they say make sense. If I understood correctly, TBN is something "man made" and can be subject to dicrepency, while TAN is "engine made" therefore it cannot be misenterpret...
quote:By all means, please continue to WALK me through the concept of/with your belief in using TAN with your knowledge of UOA's to better able grasp a real extended drain survival of the said oil. If you have some info, please share. As far as I know, it is limited and the WEAR is what you need to look at. Please advise me how to read the TAN... Please show me how and why it will be different than a TBN. They go hand in hand and as far as my understanding is, the TAN will only move when TBN is getting too low... The TAN I have in my oil is usually 2.0-2.5 VIRGIN depending on which one I use... usually 2.5 the TBN depends upon the oil is over 12, sometimes a little higher. So if you have a formula or something please share. All I know is that WEAR speaks for itself and theres gonna have to be a lot of talking to change my mind on that one.

quote:That's okay, I tried it and it would crash my computer every time. Also I started having problems seeing PDF files, they no longer pull up automaticly. My opinions differ in form from the mainstream anyhow. I also rely on the opinion of those I work with and IMO they would include a TAN if it was important. I'n not saying it has no value... But just haw far can a point rise when it is at a 2.5...and if the same rules apply to the TAN as the TBN in giving a possible ERROR, even the more to rule it out IMO. There are oils out there they would I think condemn at this level and mine starts here.. again I'm speaking through my hat on the TAN's, I have no real hands on other than a few times. So if anyone can straighten my thinking I will heed/heel to facts and consider what I find.
Originally posted by Baveux: Robbie, I'm far from being a specialist but if you follow the link in a post above you will see why they beleive that the TAN is a better measurment of the oil degradation. I'm a bit disapointed to see that a lot of the "specialist"here aren't participating to this discussion ... Where is Mr Terry ????
quote:Drstressor has much more education in regards to chemistry than these others though. I would trust what he says. Another thing to consider is that if Wearcheck as a whole company thought TAN was more relavent than TBN, then they'd include TAN on their MOB2 reports by default instead of TBN. If you want TAN, you have to pay extra for it, but TBN is included in the MOB2 package. [ January 07, 2004, 11:06 AM: Message edited by: Patman ]
