No more If I'd. Dialysis for your oil

If it's good for the environment and helps extend oil changes why isn't the OEM jumping on such a concept?
 
all they basically do is removing solid particles from the oil. but it says nothing about restoring oil's chemical properties. most of the times oil in turbocharged engines or heavily driven ones is either sheared, or fuel dilute, or both, or oxidized etc etc etc. [censored]. I don't see anyone buying this [censored]
 
Also detects people who are likely to, say, start another thread on the exact same topic shortly after this one.

Maybe they thought there should be one with a title in English. What does "No more if I'd." mean?

This doesn't sound like a great idea. It looks like a bypass filter you use every few thousand miles rather than just adding a permanent bypass system. Rather expensive for what you get. Like many crowd funding projects, it appears to be a solution in search of a problem and not very well thought out. The end result isn't going to save money.

This does nothing about additive depletion and loss of viscosity (especially in turbo GDI engines known for fuel dilution problems). I notice they still recommend having your oil analyzed, since this part-time bypass filter can't make used oil new again.

The DIY crowd would rather change their own oil than use this silly thing. For most people, routine oil changes are the only time other critical safety items such as brakes and tires get checked... for that matter how many average car owners even check their fluid levels between oil changes?
 
The basic idea makes sense, but more as an oil nutter DIY project, rather than buying this gadget. It could be combined with a revival of the winter-summer oil change idea.

The advantages are:

Packaging: Younger cars than mine don't seem to have ANY spare room under the bonnet, so adding anything is a challenge.

Failsafe: If something goes wrong offline you might have an oil slick if you havn't arranged containment. If something goes wrong with an online bypass you might have a seized engine.

Control: Online you pretty much have to assume operating engine temperatures and pressures. Offline you could change those. For instance, you can get high performance spun propylene filters for drinking water here quite cheaply but they have a maximum temperature of 60C.

When I had metal settling out of my oil, even simple offline sedimentation under gravity might have made a useful difference over six months
