Recently I was shopping for parts for my Audi on Amazon and it recommended to buy a K&N filter. The model for my car was PS-7015.
I normally use Mann or STP if I buy from Autozone.
The K&N filter looked similar to what I normally buy so I installed it and forgot about it. Unfortunately, the filter reminded about itself very quickly within a couple of days with substantial smoke from the engine compartment and subsequently a low oil message. I drive 100 miles a day and am normally very busy. So I thought I had spilled oil and hadn't filled the engine well so I topped it off with a quart. After 3-4 days the smoke was still there and got another low oil message. This time I thought the cap needed to be tightened which I did -- at that point there was a visible oil discharge from the filter housing. After a few days again the oil was low.
So, in 700 miles I wasted about 3 liters of oil.
I chucked the K&N in the garbage bin and replaced it with STP with the first chance I got. Wasted $9 on the filter and $20 on oil
When I was throwing it way, I compared the big gasket to the STP gasket and while visually they looked similar, by touch it was clear that K&N was slightly thinner.
