vs
Oil filter LIQUI MOLY or K&N
Reviews
Personally I like K&N filters, they come with a nut welded to them so you can use a normal wrench instead of a filter wrench. Gotta be careful not to over tighten them though
Pros: nut welded to them
Cons: careful not over tighten
Vehicle:
Subaru
$65-75 for 5 quarts of liqui moly and a filter. I do oil changes myself cause they are too easy not to and I don\u2019t trust anyone.
Pros: easy to do
Cons: don't trust anyone
I have a kn 1 on my truck and winter is about every 1k miles I empty it. Its the 6oz canister and usually about half full. From may till like October I dont even have to look in it because it doesnt get more than an oz of oil build up in it. But man winter time with the condensation sucks.
Pros: little oil build up
Cons: condensation sucks
Mileage: 1000 km
That won’t happen if you were using a K&N oil filter. All these cheap brand filters are not sturdy and will collapse when you’re trying to take them off when stuck… either The Black K&N select filter or the white Premium filter will avoid this problem from happening…
Pros: sturdy, avoids collapsing
Cons: cheap filters collapse
Also the K&N oil filter is superior to HD’s despite the recent upgrade. The K&N has a better flow.
Pros: better flow
K&N HP1002 because it has a hex on the end that makes taking it off through the wheel well really easy. Don't even have to jack up the car, just remove the rear splash guard.
Pros: easy to remove, hex end
Part number: HP1002
K&N is good but sacrifices filtration for flow for better performance.
Pros: good performance, better flow
Cons: sacrifices filtration
Vehicle:
Acura TLX
Not sure about mobil1 filters, but stay away from K&N oil filters. I've just used one for an oil flush after extensive maintenance work, and after just 100 km it had collapsed.
Cons: collapsed after 100km
Mileage: 100 km
K&N filters are some of the worst quality filters on the market.
Cons: worst quality
KN filters are gay, watch freedom worx YouTube video about Oem vs KN filters. You'll wanna swap right back!
Cons: KN filters are gay
Vehicle:
Infiniti
