2008 4runner v6 4.0 175xxx miles
I’ve owned since 84,000, M1 5w-30 synthetic every ~6000 miles.
Doesn’t burn a drop and everything runs fine. MPG is lower than these rigs are supposed to get, most average about 20 highway (non interstate), most I’ve gotten is 18.
Recently, I’ve been noticing some staining on the rag when I check my oil. I can’t say how long this has been happening, as I never gave it much thought. My oil changes usually come out fairly dark (think a nice milk stout). I know color doesn’t mean much upon used oil, but the stain on the rags seems like there’s an oil stain and a darker gets in. Most recent oil change was only 200 miles ago
Any guesses what this is, is it a problem, and what should I do about it? Thanks so much!
