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!

Oil change and tire rotation every 5K for me.

8 quarts Motorcraft 5W-20 with an Motorcraft FLA1 filter.

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

I previously used Mobil 1 and ran anywhere from 5-7k with motocraft filter. I just switched over to Amsoil OE 5w20 with Pure One filter and will run it the same.

I run Penzoil platinum with a K&N filter and change mine out about every 5,000 miles. Depending on what oil you go with determines the change interval. Non-synthetic should be every 3,000 and full synthetic is good for 5,000+ depending on driving habits and your climate

7 quarts i hope you mean. our trucks dont take 8 quarts. and it shouldnt take an fl1a filter either, they go on older 5.0's and 4.0s

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.

Normally, yes. But after I installed my Pro Comp skid plate, I couldn't reach the oil filter. To avoid having to take it on/off every oil change, I installed a Trans Dapt 1127 Oil Filter Relocation Kit. That extra 30" of hose and the larger FLA1 filter takes about another quart - for a total of 8.

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 had great success with Motorcraft 5-20 and Motorcraft filter changed about every 4000 to 4500. Has 118,000 and the level on the dipstick braely moves between changes.

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.

i dont get why people are running synthetic oil at 5k intervals, its more expensive than the motocraft oil, and wont net you an mpg gains. motocraft oil is designed to be run for 5k, so what justifies the price difference?

Synthetic is just better for the engine in general and I've never had issues with synthetic. I'll stick with that.
