There would be zero oil in the filter at oil change time with that design. Least messy filter removal out there.

This is assuming that you're smart enough to let the engine/car sit for a little while after shutting it off. :)

I air cooled 911 uses only 'aftermarket' Mahle oil filters.

I wrote a long post about auto parts and the parts business but must have gotten distracted before hitting “send.” The cliff notes version is that the consumable parts that you buy from the dealer parts counter are inferior to the ones put on your car at the factory. There are different tiers for even name brand parts.

I’ve told the story here before about my friend with an indy MB shop that only uses dealer parts. He realized a long time ago that replacement brake pads never last as long as the original ones on cars that he services exclusively. It’s a marked difference and impossible not to notice.

I have a 2022 Chevy Malibu that I use for Uber and it has 64k miles as of today with the original pads and rotors nowhere near needing replacement. At the current rate, it might be at 100k. I don’t ride my brakes and I’m pretty smooth behind the wheel but still…can’t believe it. I wear out brakes in normal time on everything else.

As far as filters go, there is just no reason on earth to use crap. OEM or even dealer filters are usually cheap. In some cases, like the fuel filter for my Power Stroke diesel, the dealer or OEM filter has patented features wrt where it touches the bypass valve that makes it impossible for an aftermarket filter to be the same.

Just what I said yesterday:

I’m or talking about parts from FLAPs, I’m talking about parts from the dealer’s parts department that are different from what came on the vehicle originally.

I’m well aware of the difference between OEM, OE, all of that ****. It goes deeper than that.

I wonder if Fram's are better than those old JC Whitney filter canisters that used a roll of toilet paper as filter medium....

Maybe Project farm will test them.

^^^ My first car was a 66 Chevelle with a 283 that had the cannister oil filter holder. Put any brand in and go.
The first oil change I did myself, I didn't dig out the gasket and when I replaced the filter it doubled up. I stopped at a store and a guy shouted at me.."You've got oil leaking like crazy!'
I had lost most of it, replaced the gasket, filled it up, and went on.

I had a machinist work for me for 9 yrs. Before me he spent 28 yrs at a plant dedicated to making Fram (and oem) filters. One of the best employee we ever had.

Now see, that’s where the problem starts….🤪

I bought a filter for my wife's Corolla last week from the dealer and it was around $10.00.
Why mess with it?

To those who have seen Lake Speed Jr's videos, this one is interesting regarding filters. The main part is about him making a custom oil for his Boxter. The filter part is towards the end at 17:45 where he gets into the difference between high mileage and regular filters.
He discusses that in order to make high mileage filters work with the less frequent changes, they are less efficient than the standard filters.
Lake also is against any more than 5,000 miles between changes and uses WIX in his car.

Picked up some fresh oil and a new filter for the Silverado. It's oil still looks pretty good but I will probably change it anyway in a week or so. I really like this "oil in a box"!

$22.98 for the oil and $4.16 for the filter....not bad! :)

I’m for less plastic waste and have bought the cardboard boxed oil. The valves leak a a little and i just kept the box right side up with the valve facing up.

Isn't the parent company filing Chapter 11?

That's a whole 'nother ball game. The TP filters used a significant bypass. I would guess they filtered 10% of the oil, if that, on each full exchange of the 5 qt's or whatever your vehicle required. The TP did remove particulate and water. That was a bonus. What was not so good was 90% of your oil was being recirculated with a random 10% being filtered unless your retained the stock filter. Some did not because the kit required you to remove the filter canister.

I realize that a normal filter has a bypass and the oil that goes through it is a random selection if the bypass opens. Turns out, some engines have a by pass in the block. (Porsche, IIRC), those that don't rely on a filter that does. The delta is about 10 lbs. differential from OP going in vs. OP coming out. A clogged filter will have a larger differential letting more oil bypass. Remember hot oil has less pressure so that can drop the delta.

Does every engine and filter send 100% of the oil through the filter and oil cooler, if equipped? I guess you need to know your car or engine driven equipment. Do some filters allow more oil flow and thus less differential? You bet.

Yep
