2007 BMW 750Li with 112K miles. How good is the OEM BME TPT 0w30 LL-1FE oil for my car? I love my car and I am planning on keeping it for few more years. I keep reading on the forums that FE oil is not good for older BMW's with high miles, and that a thicker oil (such as PP 0w40) might offer more protection? My car does not burn oil and is mechanically in very good condition.
