I have several vehicles, my F250 has a K&N filter in it. I have had in the vehicle for 100,000 miles. I now have 170,210.4 miles on it as of yesterday when I put gas in it. 460cid. V-8 I get the oil changed in this vehicle every 3500 miles, I also put a new oil filter in it. I inspect it every oil change, and every 13,000 I clean the K&N (I know a bit of overkill) I think they say every 25000 depending on the driving conditions.
In my xyl's van a Ram Van with a 318cid. V-8 we do the same it only has 100,000 on it. As of last month.
In our RV we have a V-10. When we changed the oil the first time at 4500 miles, it had a K&N fiter in it from the previous owner. I took it out at 15000 miles and put a new one in it.

i have noticed no significant change in the mileage of any of my vehicles.


I use semi synthetic oil in all of my vehicles.
