yeah 15.1 is good for alternator charging, but resting voltage below 12 is not considered normal as far as i can tell. Do you have a powerboost with the aux battery?
11.9 volts is a concerning voltage - this is coming from a powerboost guy with the aux battery behind the rear seat and the extra considerations that must be taken for us powerboost people. just a heads up
Right on - I'll let you take it from here.
I am guessing your AUX battery needs replacement, and due to this, it's been sucking the main AGM dry. I would guess you're going to need to replace both (main AGM replace with an H7) and then just do the fan speed 5 trick, disconnect the truck when...
this sounds to me like your aux battery (the second one). disconnect it yourself and measure the voltage, lots of posts on here (including one from me) about potential issues.

I'm sure changing the oil frequently is good enough to get the engine to 94k miles - but if the intent is 200,300 or even 400k miles, then it's a whole different ball game...
Thanks for the reply, I agree - however, oil quality is directly related to turbo longevity. This is where I started thinking about improving oil filtration and ended up on these products.
I've recently been looking at further oil purification options in the hopes of making the ecoboost engine last even longer.
Options like InsaneDiesel 1 micron bypass filter (they confirmed the kit will work with the f150):

Kleenoil as has one, but no...
Based off that image, it seems like the GPL 205 covers all areas.
Would be great if there was a demo video to show you how to do it right
Based off my research, Krytox GPL 205 is the commercial name for the Ford branded Rotunda 164-R4906.
The best pricing I've been able to find is through...
I want my key fob to always get the truck to sync to my phone and my wife's key fob to let the truck sync to her phone.
Is there a way to do this? It seems as if the truck always wants to connect to her fob.
Thanks,
honestly man, the best thing you can do for your sound system is to sound deaden the doors, floor and rear wall. won't solve your front centered issue, but should make it a lot cleaner and the difference is huge. cheers
