I'm just wondering if anyone here knows the exact oil that comes stock in new 300c's. I already know the weight is 5w20, but I would like to know the brand and the type of oil (regular dino oil, semi-synth or full synth.) I switched to synthetic today, and the dealership told me that it wasn't worth it because the car already comes stock with synthetic. I'm pretty sure it doesn't, but I would like to know exactly what it does come with from the factory.
BTW, I put in Royal Purple 5w20 today (Same brand I currently use in all my performance cars) and it made an absolutely huge difference. I've have never felt the car run so smoothly or quietly, even when it was brand new. I'm expecting slightly better fuel economy too. The car has 25K km on it using the dealership oil (Changed every 5K km) I would definately recommend this product to others.
