Hello!
I will do the 2 year maintenance next week. Today has been exactly 1 year since my last oil change (5w30), and I drove only 3,2k miles (rushing quite a lot though).
I have today a 0,7 miles trip (highway) and I am a bit worried about if I should use another car or it is completely fine to drive my car with 1 year old oil
I know some of you have done some oil testing after you oil changes, maybe you can tell me some thoughts about if
