Re: Engine Oil

Not all of the dirt that makes it to your airbox gets to the throttle body - you've got a filter for that. So some tiny amount of some other tiny amount gets by and into your oil if it doesn't get incinerated and shot out the exhaust first, finding its way into the filter and then maybe out. If a car tends to find its way into dusty rallycross stages or dirt roads, I could see this being a bit more of a concern. For the casual city car? Probably about as much of an issue as throwing that pinch of salt in a lake and noticing by taking a drink. I don't use a K&N, but I'll feel free to defend it only as it's unduly discredited by empty words like "more" and "worse".

Re: Engine Oil
after replacing my maf sensor i deposited the k&n that came with the car in the trash. the largest issue i see with the k&n is that the oil and dirt coats the maf sensor hot wire and deforms it due to the extra heat, doesn't seem to matter on american cars but i have a stack of questionable asian mafs that i took out of cars with less than 30k because the owner over oiled the k&n.
as far a oil, i have recently been buying bmw full synthetic from the dealer. it's castrol full synthetic and they sell it cheaper than the castrol brand does at auto stores. |

The city you wont see dirt roads, and its highly unlikely you will find dirt just kicked up by the tires. Now of the dust that "could" be in the air a properly oiled K&N will stop enough of it that what ever does go through wont be able to do any damage. Again that is city life, You want to talk country that is a way different subject. |

Some bit of silica gets past the best-in-test filter, too. How much is too much? How much is worth talking about? What's the difference between one stone and two stones when compared to a quarry? It's either "100%" or "negligible". Regarding over-oiling the filter... Isn't the solution to not over-oil the filter? Burned my dinner? Blame the oven - it's a piece of crap... it burns food! You can't blame the hardware on operator error, no matter how many lawsuits suggest otherwise.

Re: Engine Oil
If we're comparing questionable merits to questionable detriments, why not just go for the place we can really measure? The wallet!
