QuestionSorry to bother you with such a simple and probably stupid question but nobody i know can help me. I have a 2003 ford f-150 crew cab and until now i have never really been interested in mechanics but i am now, and would like to change the oil in it myself. I looked through the owners manual and it recommended 5w-20 oil. My question is, i obviously have to drain the old oil out but i have no idea where the cap is to do that and the manual didn't say how. Also, which brand of oil would you recommend and which oil filter would be needed? Also is there any trick to draining the oil and replacing the filter or do i just put a bucket under it and open the cap? Sorry for such a stupid question and i understand if it is not worth your time to reply. Thank you in advance!
AnswerBlaine, the oil change procedure is rather elementary, and some customers simply enjoy doing this operation themselves. However, it is a lost opportunity for an 'expert' to discover problems with your vehicle that could save you down time and money later.
The drain plug on the 4.6 or 5.4 engine is still on the bottom of the oil pan. It will take a 5/8" or 16mm wrench to remove it, and let the oil drain into a pan. The filter is a little difficult to get to - turn the steering wheel about a half-turn to the right to clear the tie rod and pitman arm, and look at the front driver side of the motor - the filter is a Motorcraft #820, with many equivalants available at any parts store. You may need a special wrench to loosen it, then unscrew it by hand making sure the old rubber gasket comes off with it. Install a new filter, tightening it about 1/2 turn after the gasket contact is felt. Then, refill the oil with 6 quarts of 5W20 quality motor oil, and crank the engine. Let it run about 15 seconds, shut it off, and check the dipstick level and look underneath for any leaks.
I would recommend a Motorcraft filter, because it is made for your engine to the specs that Ford recommends. A Fram or STP filter may be fine, but I know the Motorcraft is absolutely right.
I personally like Valvoline, Texaco, Exxon, Shell, or most other motor oils... I do not like Quaker State or Pennzoil (the Pennsylvania crude has a high parrafin content, and years ago I worked at a dealer that used it - many engines were full of sludge after 60,000 miles on that oil!)
The oil and filter are most economical at AutoZone, Advance Discount Auto Parts, etc. and a selection will be available. Pick up an oil filter wrench, too, that fits the end of the oil filter! Most of these stores will also recycle your old oil, too.
While you're doing the oil change, check the air filter, the front suspension, the brakes, the tires and tire pressure, the other fluid levels, etc. Also, rotate the tires every other oil change, and have an alignment done if you start to see unusual wear patterns on the front tires.
Hope this helps!
