Welcome to Noria's new Lubrication and Oil Analysis Message Boards.

We think you'll find our new interface faster, more user friendly and a better way to communicate with other lubrication and oil analysis professionals.

To kick-off the new message boards, Noria is giving an electronic copy of Jim Fitch's new book How to Select a Motor Oil and Filter to the first 10 visitors that register and post a question, tip or case study (relevant and meaningful posts only Smile ) to our new boards.

I have a question regarding TAN. We recently got back our oil analysis on our hydraulic presses, including TAN's. What do they mean. Our highest TAN on one of our presses is 3.4. Is that an acceptable number? I can't seem to find this information either from the lab or the manufacturer. We use Mobil DTE-26. Running an average temp of 110 to 115 deg. the ISO code was 11/8. any sugestions? Thank You, Chris Ward, Entegris Inc.

Hi Tiffr
Re "TAN" or "AN" as it's being termed lately.
TAN is a trendable item watching for rate and amount of change.
It is a good indicator but I would checking, viscosity, water, Oxidation figures and if there was an increased in chemcially gelled lubricant agglomerations before I took any action. If your new lubricant had a TAN of 1 and the TAN figure of 3.5 occurred over a month then I would definitely be checking why.
If the change was over 2-3 years it may be "normal" but I would still would like to complete a complete a patch test or filter gram just to check for amount of damaged lubricant in the sample.
