This is what concerned me originally and why contacted Mobil1 support when the filters were being made by Champion labs which was also making the OEM ACDelco PF64 filters at the time. I don't know of anyone with a C6 actually contacted them to verify the bypass pressure, it would have been...

M+H might not have realized that the Mobil1 catalogue was cross referencing the same filter for both bypass pressures when they became the supplier. The M+H and Champ labs M1-113A filters are definitely different designs even though they share the same Mobil1 part number. Right now I'm taking...

Probably because M+H is already telling us that their M1-113A has a bypass pressure in the 15 psi range and if you want higher you need to use a M1-114A filter with a 25 psi bypass pressure.

Yes, the engines were covered under warranty by GM. The assumption is that if you install a bad OEM filter and it causes an engine failure while still under warranty that GM will cover it, but I have never seen anything in writing other than the filter itself being covered. Nor have I seen...

Actually, there were a few C7 engine failures that were attributed to contaminated ACDelco PF64 filters (one was a press car under review). They were covered under warranty but still a hassle. But in my case I'm just trying to make sure the three Champ Labs M1-113A I have sitting on my shelf...

I don't know. Their signature line from Champion Labs (now [email protected]) is below:

FWIW, I asked Champ Labs to verify the bypass pressure they had previously told me (18-24psi). They responded with the below message: "After reviewing with Engineering. The old Champ supplied Mobile1 M1-113A, has a 18-22psi bypass relief rating. As we no longer supply Mobile1 and the Champ...

The later Champ Labs filters also had the A suffix. It indicates they meet the 20K mile change requirement. Interestingly enough, the M113A's mad by Champ Labs and M+H have the same Mobil1 part number.

Mann+Hummel.

But the question is does Mobile1 provide all the specifications for each application and have the supplier comply with them? Or does mobile one give general requirements (housing thickness, media construction, etc.) and rely on the supplier to determine which filters meet the application...

I get the feeling that Mobil1 gives general specifications and relies on the filter manufacture to come up with the detailed application specifications. If you look at the filter warranty, it is by M+H and not Mobil1.

I did call the Mobile1 hotline and the M+H representative confirmed what the Corvette forum poster said. He also asked me if I was the person that just sent an email (I wasn't). I suspect what is going on is two different manufactures with different approaches on how to meet the...

He was told that the M+H M1-113A has a bypass pressure of 12 to 15 psi and the M1-114A has a bypass pressure of 25 psi.

That's what I thought when I got the answer from Champion Labs. It's just the the M+H answer got me concerned again. I didn't want to do anything that would jeopardize my warranty even though Mobil1 guarantees that they would cover any damage to my engine caused by their filter. Below is my...

^^^ I'm trying to decide if I should use my three Champ Labs M1-113A filters on my 2020 Corvette. Doing some reading here, some people don't seem very concerned about using a filter with synthetic media even if it has a lower bypass pressure. And I live in a moderate climate. I'll rarely (if...
