So here's probably the same old question, I'm guessing. I have been using Motorcraft 5W-30 with a Motorcraft FL-820S filter. I buy 5 quart jugs two or three times a year (if I drive to FLA four) and there always a backup for that last .07 of a quart and the usual top offs. I always buy the oil and filter in advance so I can change on the spot when needed. Here be the situation, every time I go to buy a new jug the the price has gone up (what else is new). Use to cost $20.00 or less then goes up $2, then $3, now $4 locally now its $29.99 and have to drive to get it at that price now. My local parts stores no longer carry 5 quart jugs and If I want to buy it I need to get it by the quart and its 7.49 - 7.99 a bottle (almost double the jug price). Forget online pricing seen it as high as $80.00 (FOR Motorcraft OIL). Thinking of switch brands I can get locally or delivered by WallyMart (save that gas). Thinking either Mobil ! HM or Rotella Full Syn. The question: Should I change filers as well, or keep running with Motorcraft filter? Oil recommendations welcome. Thanks in advance to all answer as usual.
