Oil Filter Recs

[Timmayy!]

This is a very personal opinion driven topic but i think its important to get any parts of information that I'm not privy to. They all have pros and cons and i will list my choice below. Keep in mind I'm a 5000 mile Oil and Filter change kinda guy so i know this probably matters none but i cant help it. I will be putting in Mobile 1 EP 0w-20.

 

Wix:

Pros: Synthetic wire backed media,  Correct bypass pressure setting of 22psi

Cons: 50% efficiency for particles 20 micron or larger

 

Fram Ultra:

Pros: Reigning BITOG champion, synthetic wire backed, 99% efficiency for particles 20 micron or larger

Cons: Incorrect bypass setting of 9-15 psi

 

Mobile 1:

Pros: Correct bypass pressure setting of 22psi

Cons: Semi-synthetic non wire backed media.

Unknown: 99% efficiency with particles 30 micron or larger (IDK how this compares to the other two testing standard of 20 micron)

 

I have taken the belief that the bypass valve pressure setting is important and i have all but written off the Fram ultra (even though it would be my first choice if it had the correct setting). The Wix efficiency really turns me off even though in all reality it might be better than mobil 1 when compared on same scale. My guess is its a comparable efficiency to the mobil 1 considering they are both trying to make 20K mile oil filters.

 

What say you

Don't know, I use Amsoil filters.  Since I found Amsoil, I won't use anything else unless it's and emergency.

I actually just called Amsoil and they also only have a bypass setting of 14-16psi. So for the time being personally i rule them out

ACDelco PF63E.  Only one GM calls for. 

[Timmayy!]

I thought it was general consensus that the PF63E was bad because if the ecore

Amsoil is my vote

[Timmayy!]

So for those that are picking a filter not speced for the updated bypass pressure (i.e. fram and amsoil), is there a reason??

[Mike GMC]

For me, it's the nanofiber filter material.  It traps more dirt and simultaneously flows better than paper.  As such, it still works when others are loaded.  It's the only filter that I trust to last for the entire drain interval.

 

Basically, because of the nanofiber filter, it will still be working when others are in bypass, even with the lower bypass pressure.

 

 

This is for Amsoil, not Fram or others.

I prefer the Wix but usually get the Mobil 1 the same time I get the oil at Walmart

I usually get Wix but have been getting the Baldwin Filters B7449 for my 2018.

Does the bypass only kick in when the filter is dirty? I thought it was in bypass more often than that (like cold and high demand), which means a lower bypass is passing unfiltered oil more often. But maybe not often enough to justify a lower performing filtration medium?

Anyone get their oil changes at Valvoline Instant Oil Change?

I've been going there for the last few years using Valvoline full synthetic, and I heard they use a Purolator filter with a Valvoline label. Anyone know the truth?

If it wasn't such a pain in the ass to dispose the old oil I'd just do it myself . I just might start though they charge $110 with a $10 off coupon . Rip-off if you ask me. I'm not going to use my two free oil changes from the dealer either. Took 2 hours last time I went there.

That is not the information I got when I called AMSOIL Tech support.  They informed me that the EaO17 has the proper by-pass setting per GM specifications.

My guess is that tech was unaware of the spec change of the filters for the 5.3. 

 

If you look look at the pf63 it’s bypass pressure is 15psi (which is what the amsoil filter is per my questioning amsoil tech) 

 

the pf63e bypass pressure is 22psi. There is a bulletin passed around about gm saying that using and oil filter with a bypass setting of 15psi or less could introduce particles and increase engine wear. 

 

When end I called the amsoil tech I didn’t ask whether the ea0 17 would work for the 5.3, rather I asked specifically what its bypass specs were. He had to go look it up from some other manual but he informed me the bypass pressure setting was 14-16psi.

This in theory is partially true if the nanofiber does flow better (have a lower dp after xxx amount of miles). 

 

However the pressure bypass plays a much bigger role under load and when engine oil hasn’t warmed to operating temp.

 

When under load you oil filter is seeing a high upstream pressure due to the pressure supplied by the oil pump. The restriction of the oil filter naturally creates a dp depending on the bypass setting determines whether or not oil will flow through the filter or not. A lower dp setting will cause the filter to be bypassed more often. 

 

When cold the viscosity of the engine oil creates a higher restriction therefore a higher pressure drop causing the filter to be bypassed until the pressure setpoint is reached. So the lower the pressure setpoint the longer the filter will remain in bypass while the engine warms up. 

 

There isn’t any statistical specifications (to my knowledge) that state the dp across the oil filters for comparison and just from my intuition I don’t believe it would be vastly different to cause one filter to be in bypass while another is not (all bypass pressure settting equal). 

 

I truly believe it to be more more important to follow gm specifications regarding pressure bypass settings rather than have a full synthetic media or nanofilter tech. That’s just my opinion and I would love to hear everyone else’s thoughts.
