Very helpful. I'm new to the really scientific parts of oil analysis, and this definitely helps me understand one of the actual testing methods.

Thank you for describing the difference between FTIR test looking for oxidation byproducts of the oil and the RPVOT TEST measuring how much oil can resist oxidation.

Raff, i think it would be also profitable to hear about the rpvot values comparing to aminic and phenolic AO corresponding with the additives working temperature and how it compares with RPVOT in modern oils. Maybe good idea for new video :)

Great suggestion! We covered it a little bit in the Phenol and Amine videos way back but it's probably a good idea to tie it in with RPVOT.

PDSC (Pressure differential scanning calorimetry) test is also kind of a similar test which measures OIT Oxidation induction time

It would have been great to include TOST as well here.

Glad to found your channel. Great video. One question could you tell us a bit about your education background.

Education wise I trained as an aerospace engineer 😊 Fell into industrial lubricants!

@@LubricationExplained are you trained to an ICML level? Eg MLA or MLT if you know what I mean? Your content is good and has a mix of theory and practice like some courses I have done.

@@jediali221 No, I'm not. In fact, what I'm trying to do is provide an alternative to ICML. Don't get me wrong, I think ICML (and STLE) and the associated training organisations provide a great curriculum - but it's really targeted at lubricaiton professionals. I think there's a lot of people out there for whom that style of training is massive overkill and the cost is way too high. The people I'm trying to hit up are engineers and technicians that might only need an understanding of lubrication in their specific application area. What's your background? And did you take MLA/MLT?

@@LubricationExplained that's interesting and totally understandable. I agree a bitesize approach is useful. I am a degree qualified and chartered engineer dealing with rotating Equipment and other mechanical maintenance in the oil and gas sector of Scotland. I have been lucky to have had time and budget to get up to MLA2. I am mostly dealing with application of lubrication best practise in maintenance role so the chemistry side that I am learning from you is new to me.

@@jediali221 Oh awesome! Like I said, I think the likes of Noria and co. do a great job of training people. I probably have a slightly different teaching approach because I feel like I understand the application best when the chemistry is made clear. I guess it's more of a "first principles" approach to understanding lubricants. I don't think either way is better, just different. Funnily enough, I have a pretty similar background to you in that I worked as an engineer in the oil and gas sector for a decade - I just never got round to the ICML exams. I've got a little more time on my hands these days, so maybe I'll have a crack!

Great Video and great learning. Please help to resolve below query. 1. Why only copper used as catalyst. 2. If manufacturer cheat by adding anti copper oxidation additive then can we use any other element as catalyst ? 3. If we don't have reference RPVOT value then is there any reference available to compare with original ?

Good questions - copper is generally used as a catalyst because you'll find copper in a lot of machine designs, whether it's the oil coolers, or bearings materials. Copper is both a catalyst, and susceptible to corrosion, so it's a good one to include. We could use another catalyst, but then the manufacturers who are cheating the test would change to a different additive system - so if we changed it to platinum, they'd load up the formulation with platinum passivators. If you don't have a reference then the best thing to do is trend results over time. If you continue to use RPVOT to test the lube oil system the number will drop further and further, and you can use the rate of decrease to predict oil life.
