y'all are gonna hate me.
First off - per other SAE studies. With a good filter and some time, i like a 5K change. with a good filter and some synthetic I trust, I will go until the monitor goes off.
However - what do I trust is a very short list. M1, Amsoil, and Castrol.
but as said if you just can't stand it - change it more often - hurts nothing but your wallet.
But my biggest thing - run a filter magnet. I don't care if you use cheap oil that you change often. I don't care if you use some magic brand filter etc (I prefer wix). I don't care what you drive.
USE A FILTER MAGNET!!!
Now I'm not also selling those 59 dollar filter mags from Jegs or Summit etc. Use what you can find easily.
I use the magnets off the heads of sonicare toothbrushes, or magnets out of a harddrive. Yes really. Why - they were free. And guess what they are strong enought to stay on the filter of a 500 HP v8 car in Memphis City traffic over a 6 month period.
Then they are also strong enough to pull iron metals to the sides of the filter. And again - cheap.
Meanwhile in my family car I use 9 quarts of Amsoil 5-30 and a wix gold filter.
for my new focus - I intend to use Amsoil in it too and some filter. That is up for debate currently.
If guns kill people, spoons cause diabetes.
My other car is a 4 door family car.
