[05 sport trac]

its about that time for an oil change and now new spark plugs. What kinna oil and plugs do ya'll think r best for the trac?

A full synthetic oil for sure. I prefer Amsoil. For spark plugs your best choice is Motorcraft.

Plugs, either Motorcraft or Autolite double-platinum. DO NOT get multi electrode plugs like Bosch, they do not get along well with the Ford ignition system.
Most any synthetic oil is fine, I occasionally send my used oil to a lab for testing and I get the lowest wear metals with Pennzoil Platinum (although I have not tried every oil there is).
Regular Mobil 1 5w-30 was fine.
Curiously, Mobil 1 Truck & SUV 5w-30 was awful in the lab tests so I wouldn't recommend it.

Just changed my plugs with AutoLite APP103 dbl platinum. I'm not one for exotic plugs of any kind. Radio interference, ignition incompatibility.

You'll need to take off the front tires to gain access to the heads. I used a piece of rubber hose to help with the re-install on the right bank. Slip it over the top of the plug, guide it into the head and twist . You'll also find it's easier to use a wrench on the plug socket hex rather than a ratchet. (I've got every flex socket and flex head ratchet known to man and still used a box wrench on at least two of the cylinders).

The old plugs came out pretty easily, but I always "crack" them in the tighten direction first. Engine runs great, but I'm thinking about an O2 sensor next- idles a little rough.
