I agree; the added oil level height from an extra 3/10 qt is not a deal breaker.I'm sure there can be some variation between engines also as 6 quarts with a 400 equivalent filter puts my cold oil level just a tiny tad below the top of the hashmarks. While I completely agree with Marks comments, the oil quantity between the top of the hashmarks and a tiny bit over is insignificant at best. The foaming mentioned is typically caused by the crank splashing around in the oil when the pan quantity is too high (not a good thing). 3/10's of a quart is NOT going to put this engine in that condition. And in reality, we're talking about less than 3/10's because the larger filter is holding some of that 3/10's inside the filter and not in the pan. All in all, 6 quarts even with the 400 filter is zero threat.
What is the mobile one equivalent???Mark is definitely an expert and as he points out for exactly the reasons he listed, if 6 quarts puts you over the hash marks on a cold engine, take some out. You can do the 5.7 fill and add more the next day if you want.
As for the higher rated bypass valve, I always figured it was all sixes since the larger surface area of the filter would allow more oil to pass through it, making the difference between bypass valve ratings more a moot point?
I've always just ran the M1 equivalent. Since its larger and has a lower bypass rating than the 400S, it always fit the bill for me pretty well.
Lol, not this again.Never use Fram. They have been know to come pre rusted.
