I have a 2006 MCS with 6-speed manual. The only engine mod I have made is a CAI I installed when I first got the car in 2009. Recently, I have been getting an intermittent red oil light after the engine has warmed a bit. But, it only happens when I have to stop at a light or stop sign and sit at idle with the car out of gear. As soon as I put it back in gear and give it gas, the light goes out and stays off unless I stop again and take the car out of gear. And, it doesn't happen all the time even under those conditions. Oil was changed less than 5,000 miles ago and I keep it topped off whenever I notice it has been burning a bit. I haven't taken it to pull any codes or have it checked out yet. Just first wanted to see if anyone else had any similar experiences and what you found out.
