Remember that Amsoil says their Ea15K oil filters aren’t only for 15k mile use. Their EaO filters are the 20k ones.
I know there's alternatives to make oil changes a bit easier (e.g. Fumoto, Stahlbus, EZ Valves) but then again, I would still need to drop the filter and replace it and IMO it kind of negates the reason to have a valve in the first place unless the filter is located inside the engine compartment like some vehicles.
As promised, just received the oil report from Blackstone this afternoon.
Came out great for 7664 mi, I usually don't go much more than this on my vehicles.
A little interesting in the way the comments were written, this time I ran the car for 45 min then left it sit for half hour or so to cool then changed oil, probably why fuel dilution disappeared this time.
Oil used was Ravenol 5w20 SFE.

If my 2.5L burns a quart of oil per 4K miles, I’d use 5W-30 oil trying to slow down the oil consumption.As I predicted in my last post/report, after 4K miles the oil level was down to the lower hole on the dipstick. Added a quart to bring it back up to the top mark. So the next time it's down a quart it should be time for my 8K mile oil change.
Here is my oil analysis from my 16.5 CX-5 with 63k miles currently. I also posted this on BITOG
I'm hoping to run the Mobil M1-108A till it's approximately 18-19k miles before doing another analysis to see how the AMSOIL Signature 0W-20 is performing. Also, to clarify, I did not add any make up oil, I simply misread the question as "How much oil did you add into the engine after the change?"
7/25/20 (OLD) Setup:
Oil Used: AMSOIL Signature 0W-20
Filter Used: AMSOIL EA15K12-EA
7/25/20 (NEW) Setup:
Oil Used: AMSOIL Signature 0W-20
Filter Used: Mobil 1 M1-108A Extended Performance Oil Filter

How many miles has your car got on it?As I predicted in my last post/report, after 4K miles the oil level was down to the lower hole on the dipstick. Added a quart to bring it back up to the top mark. So the next time it's down a quart it should be time for my 8K mile oil change.
The regen is done with the adblue or whatever mazda calls it not directly with more fuel. Basically inducing adblue and getting very high temp in the dpf to burn the soot that accumulates in it. Its all in the exhaust system. Bear in mind if you drive mostly in city more regens may happen and you may need more adblue sooner than later.
Yes, DPF regen does burn more fuel and bring down the fuel efficiency.Actually, the Diesel Particulate Filter (DPF) regeneration cycle ("regen") IS assisted by using more fuel in a "post injection strategy" to increase the Exhaust Gas Temperature (EGT) in an active regen. Some of that fuel ends up sticking to the cylinder walls due to the lower pressures/temperatures of the injection timing and then ends up making it's way past the rings and into the sump. Much of the fuel dilution in the oil "burns off" or evaporates after some time (depending on oil temperature and engine rpm). This phenomenon is why the fact that my car had just finished a regen cycle only a few miles before the sample was taken is a factor with the fuel dilution for this sample.
The DPF is the first thing downstream of the turbo (actually just behind the engine). The Selective Catalytic Reduction (SCR) is the gizmo that uses the Diesel Exhaust Fluid (DEF or "AdBlue") and is downstream of the DPF. It uses the DEF in a catalytic converter to reduce oxides of nitrogen during certain engine operating conditions (usually extended low speed/idle and high engine load conditions). The SCR may use more DEF when an active regen is going on, but it's a separate, downstream event that doesn't help clean the DPF. DEF cleans Nox out of the air, not Particulate Matter (PM) out of the DPF
Whew! that's a whole lotta letters!! lol
Here's a little video that shows the basic system .....
I just do t myself ~ 6-7 k, used a Premium Bosch filter and Mobil 1 (blackstone labs guided/test) > Done...
Believe it or not...if you are on a tight budget Amazon Basics Oil ( API certifications ) is a high quality choice for the budget minded...
