When changing the oil in my 1994 Camry 5SFE, after letting the engine sit for 10 minutes while draining the oil, when replacing the oil filter, not one drop spills, the filter is completely empty! The filter is mounted at a 45 degree angle open side down. Have tried many different types of oil filters, WIX, Toyota, etc. all with the same result. Is this normal for this engine? Have neven experienced an oil filter emptying so quickly or completely in my life. I know my filter has to refill every time I start my car if it has sat longer than 10 minutes, very disconcerning. It has the donut shaped factory oil cooler between the block and filter, uses engine coolant to cool oil, maybe this has something to do with it, none of my other cars have had this.
