did an oil change today on my buddies '05 ford ranger, 2.3 liter engine. last oil change i had used an STP 3600 filter. went to wal mart today and got the oil and a motorcraft FL910S filter. however when i took the STP off, i noticed the STP is longer than the motorcraft by at least half an inch. can this hurt anything by using the smaller mo0torcraft filter? did ford downsize the filters? the STP 3600 and the motorcraft 910S are both the right ones for this truck.
