I hear from some people that it does, but others come back and argue that they disagree. That it does not.
And that the larger capacity filter Audi switched to, is supposed to help prevent that.
I think the stock filter years ago was smaller, but now it's bigger and adds oil capacity, maybe bumping total capacity up to like 4.7 liters or something.
Mann 940/25 I think.
And I hear there's even bigger filters that can fit, which might come from Volvos, if you look them up in the Mann+Hummel filter catalog.
I hope there's no compatibility issues. Such as if they spec a different bypass pressure in the filter spring.
Anyway. What would the sludge come from? The way the previous owner treated the car?
Since they're old with miles, and are likely no longer on the first owner.
I hear certain oils have cleaning power, that you can use to slowly and safely clean the engine.
Versus more aggressive fast methods. Because supposedly they can loosen up debris that can clog the oil pickup screen, that sucks oil from the oil-pan to get pumped through the engine.
So to this I ask, is an aggressive clean worth doing? How would it be done?
I see that many engine clean products exist on the market, including being stocked on auto parts store shelves.
However, there is also the company Lubro-Moly, which seems to like claiming it's a quality German car parts company. Is it?
And if so, is their Engine Flush worth using?
If it is, should other things be done at the same time? What if the flush clogs the pickup? Should the pickup be manually cleaned or replaced immediately after?
This would add additional steps to the job, such as dropping the oil pan to access it, and cleaning the pan to re-install it with a new gasket or sealant.
Maybe BG has a product for this?
Is there still oil cleaner residue left inside the engine after a flush, that should be cleaned out by running a flush oil and a quick additional oil change after that?
One candidate would be Mobil 1 0w40 European Formula. $22 Wal-Mart rollback price + M1 Rebate form, brings them down to $12/jug (5L).
Also, why did someone smear axle grease on the cam-shafts at 0:40 of the video and then wipe it off at 1:12...
That techno music makes it sound like this $15 bottle of Engine Flush will add 500hp to my car.
Or is this just snake oil designed to make money off of people who don't know better, and want a feel-good mod,
in other words, mods that don't actually do anything, but make you feel good like you took care of the car, due to spending money on it and being a "responsible owner"
This is a car with ACTUAL sludge (Audi TT), because the oil wasn't changed for 84k miles.
I doubt an Engine Flush would make a difference on it, and none of our cars are neglected this bad.
And the camshaft lobes are still clean because they're in constant physical contact with the lifters.
