It seems like you might have pressure relief valve problem in that crap brand F filter. I would think it highly unlikely the engine oil pressure relief valve is faulty unless the car has suffered from severe neglect in the oil change department or used the wrong oil for many many miles.

Yes, when i look underneath there is oil all around filter only. ,looks like it is blowing oil out from gasket at oil filter? Like too much pressure is in the crankcase. It has happened 3 times, but only on long distance driving. I can drive 4 months in town, no oil lose, car drives great in town all day, only on long distance at high speed. I thought it was a motor defect or design flaw?
That or you have a totally wrong filter/failed filter and it's deadheading against the engine oil pump and that means you have no oil flow past the filter. This needs to be fixed. Take the filter off and take a picture of the adaptor to see if something is wrong with the mounting surface

I always check to see that the old filter gasket came off with the filter. Double gasketing the filter will do exactly what you are experiencing. Also get the large filter that goes on a 90's Ford Taurus. Better design and holds more oil. Fits the LS 430.
Fram filters are not known for their quality. Wix & Napa (made by Wix) filters have a good reputation. I use Baldwin for the same reason.
Motorcraft Filter number is FL-400s.
My guess is that you have a filter problem. I would also check for codes.

Aftermarket oil filters have no place on our engines first due to gasket design and second due to filter element.
Size for the sake of size?

Trust me, i know how to change oil and filter. It is not my abilities at task, it is a flaw in the motor? When i was at home depot, a guy offered to buy the car, he said he only buys lexus. Then he mentioned the very same problem i was talking about, that the motor has a oil leakage problem at the oil filter and it only happens at high speed long distance driving. But he walked away before i could ask him for the fix or known problem? I can't find any solution on web, but it is a known problem. I use fram filters and castor oil only on all my cars. It seems to be crankcase pressure buildup? With the motor running i have vacuum at the pcv's?
I have been on the forum for 11 years and have never seen your specific issue reported. Unlikely that it is an inherent flaw with the motor. I'd try replacing oil filter and checking PVC line/valve. Keep us posted. Good luck.

If oil lealing where oil filter bracket mates with engine block, replace gasket #15692.
