Guess I should know by now that there's always going to be some "expert" that is going to know more than everyone else. Not the first chemist I've ran into that didn't understand oil analysis though.
Good to hear it. I typically focus on industrial filtration so I'm a bit behind on who's making what for who anymore. Shoot, I just found out about Hy-Pro and Donaldson a couple weeks ago.
Amsoil and Royal Purple are both great lubricants, the best quality filter I have been able to locate for most vehicles comes from Purolator though. Last I checked, their Boss line was getting capturing 15 micron and up at a rate of 98.7%. Most of the OEM filters aren't coming close to that.
I've been thinking about the two tone as well. I have been thinking about the look of the '79 F100 with the metal strips boxing in the second tone and how something like that would look on one of these.
With "Theoretically, so long as the TBN is over 0, TAN is 0. But that’s only in an ideal world (which we ain’t in)" as your understanding of AN/BN, I concede that you will never listen to me (your understanding is incorrect when it comes to oil analysis). So you win, take joy in whatever you...
I like it. I will likely go with the same 500 mile flush and fill myself. After that, I will use whatever the manual says needs to have in it. Once the warranty is out though, I will likely move to a blend that has the titanium additive since it shows great potential for reducing engine wear.
My understanding comes from the tribological side of it, but as I understand it acid in oil travels more in pockets rather than being an actual solution. This is why the AN is used more prevalently than TAN, since it is more representative for machine surfaces.
I am no chemist though.
TAN was replaced by AN because of this. This is why when most people are using AN/BN to schedule oil changes now (at least in industrial equipment) both numbers will be charted and the change will take place just before those two numbers cross on the chart.
A good article that covers this...
PH measures strength of an acid, so you could have a low acid number, meaning a low concentration of acid, but a high strength acid at the same time.
I haven't gotten into the weeds on the engine sensors on the Maverick yet, but most vehicles with an "oil life remaining" indicator have a...
Oh, I completely agree. Consequence of failure is (should be at least) the root of reliability. This is our measure of when/if we perform different types of maintenance, or if oil analysis is even warranted.
On a side note, TBN and AN are not the same thing as PH. AN is the concentration of...
My concern would be that your AN would outpace your TBN when you get below around 3.5 typically. I always thought that once TBN hits about 50% of the original new oil value that it is in a cautionary limit with 20%-40% being a critical limit.
I'm a lube guy, so I tend to geek out about this...
