E92 330
in the last 3 days ive driven over 750 miles, long journeys! today ive gone to check my coolant and theres about 1 cm in the bottom, so topped it up! next i checked my oil, its half way up the stick. i had only just finished drivin when i checked the oil so the reading may not be accurate but its a bit suspicious, my first thoughts were headgasket?! is there anything else it could be?
