How often to change oil?
Gonna change the oil in our '04 F-150 4.6L this weekend, just wondering how often to change the oil and which oil to use. The options we considerd are:
Mobil 1 Extended Performance that gurantees oil life for 10-15K
Royal Purple which says 12K
There are also people on here who say they ran Castrol Syn. and they go 20-25K. Is that really possible? Thanks all!

Just follow what your manual says. Today's oils can certainly handle many more miles before they breakdown. But unless your changing the filter once or twice thru that extended change interval. You'll be circulating oil that's still good but full of particulates.
But like anything, this is just opinion and it's always best to do some good research to find out the info that you need.
This site may offer a bit more indepth info then what you'll gleen from all of us. http://www.bobistheoilguy.com/cms/
You can't go wrong running the OE oil/filter. Motorcraft oil and filters are readily available at wally world.
Hope this helps

to keep cam phaser problems at bay arent you supposed to stick with motocraft oil and filter? you guys switching it up had any problems?
that being said i do motocraft 5-20 and a fl820s every 5k.
ill probably do it after 2.5k or so this time, and then again in another 2.5k just to clean things out.

damn. whered it relocate it to? thats awesome! i want one of those for my truck and my mustang.
im surprised we dont see those more often, one of my old friends has a 4.7 tundra he has to pull the factory skid plate off when he changes his oil.
good stuff.
take it to pms if you want so we dont hijack. id like to see where you mounted that relocate

You can run your M1 or RP and end up with the same results and a lighter wallet. General concensous is to run the Motorcraft 5w-20 and the motorcraft fl820s filter. They both perform flawless on the 4.6 engine. You will get a ton of opinions on when to change them so you will just have to decide for yourself. I change at around the 4000 mark.

"I have been told that M1 is the best oil out there ..."
MGD
Not even close. After Katrina, Mobil went with a Gp III base which is a synthetic like Castrol and the rest, excluding the non API certified Amsoil and Royal Purple which are a Gp IV. M1's formulations are not showing any premium performance versus that of any normal dino oil. You'll generally see iron higher in analysis with M1. Some is corrosion as the non-polar properties of the base they use literally runs off of the parts when you shut the engine down. The HT/HS rating on the M1 5w-20 is 2.6 which means it is at the absolute bottom of barrel and just barely making grade....if the oil is in grade at all. For normal wear, a HT/HS rating is 2.8. HT/HS rating is directly related to bearing wear. Since you have it, use it but I would find something a lot cheaper that's a lot better next time. In regards to the Fram filters, you'll never find another Fram on anything I own. There is a thread here from a Fram tech that got hammered pretty bad as he apparently couldn't answer the hard questions. I'd try to find somebody to pawn them off on and buy a good filter. Your truck, your money.
