I have two cars one is my 06 Optima (commuter) with the 4 cylinder engine. I'm at strict 3000 Mile OCI's the car has 31K Miles on it, I use a purolator filter and castrol 5-20 (4.5 qts) and I dont even drive it hard, it's mostly highway (cruise control), no short trips etc...
Anyways, the oil always comes out dirty but yesterday was the worst. I pulled the plug and it was BLACK! I mean, I even dripped a little on my garage floor and wiht the lights on I couldnt see through it it was solid black. On my fingers it wasnt even transparant again, just black, and it stinks. Anyone else have a KIA ? I've always done the oil changes so they get down right at or before 3000 Miles. I use shell fuel and the car runs great. No smoke, not burning any oil etc.. During oil changes I even dump half a quart in with the drain plug out just to "rinse" things off and a bunch of dirt comes out.
My 01 toyota tacoma at 4000 Mile OCI's with the same filter and the same castrol 5-20 comes out golden after 4000 miles and thats a 4x4 with almost 100K Miles and I drive it hard..
