I just purchased a 01 4.6L Romeo F150. I want the longest life out of it. I want to know what is the best brand and type of oil to use to get this result?

 

Motorcraft,sold at Wal-Mart for $2.32 a quart.It is a synthetic blend and by far,IMO,the best synthetic blend out there.And,the lowest priced too! BTW,your truck should use 5W30.

Oh,I recommend using Motorcraft oil filters.Wal-Mart sells them also.

 

the only synthetic blend Motorcraft makes is the 5w-20

5w-30 comes as either dino or a full synthetic.



EDIT:

SAE 5W-30 and SAE 10W-30 Super Premium Motor Oil

Worng i have some hear it is Motorcaft blend 5w30

 

It don't matter. Use an oil with the latest API rating, I think it's SL now. Use the proper weight for your engine. Use a good filter, I strongly recommended Motorcraft. Change your oil and filter regularly (along with other basic maintenance things, fluids and filters, etc.), and quit thinking so hard about oil.

I've got 6 quarts of Motorcraft 5W30 sitting in a Wal-Mart bag on my tool shelf,which reads on the back of the bottle "synthetic blend"!
Um,Uber,you think Motorcraft slipped some 5W20 into my 5W30 bottles and misprinted the back of the bottle?
Sorry,but Motorcraft 5W30 "AND" 10W30 are synthetic blends! And,can you guess who makes this oil? CONOCO!!!!!!!

 

 

Mobil 1!!!

So you know, I just said that so I can sit back and watch the fun. It's like poking at a wasp's nest.

 

I used Castrol 50/50 for about 198,000 miles - always used motocraft and wix filters - 200,000 + and running Amsoil 100% syn now . I think it's the best , if not - I want to know. Also I've read I don't have to change until 7500. So I figured 5000 miles I 'll change it out to be safe. Great compression , no leaks and it does't burn any at all within 3000 miles.

I have a 98 5.4L tho.

Miles speak for themselves , just burn the quality stuff..

 

i think everyone can get too caught up in oil....I just check my oil level every 500 miles and change it religously every 2500 miles. I use standard penzoil in everything i own except the db9 and my bikes and never had problems.......

 

Forget oil. How you drive is what determines how long your engine will last. If you beat it all the time, and don't let it warm up on cold days, you'll tear it up quicker than somembody that treats theirs right.

 

 

You think about the tolerances inside the engine when it's cold. You don't want to just jump in and stomp the gas. If you let it warm up a bit, it will make it easier on the whole engine. This is a MUST especially for diesel engines. They make horrible compression on cold days, and you will pay the price for working them cold.
