Whats the best oil and oil filter I should use in my 4.0EFI, I know from the mustand 5.0 the best filter is to use the motorcraft filter?

 

You're not going to get a definitive answer. Here's what I use:
Mobil 1 Synthetic
K&N Gold Oil Filter.

For interesting reads:
One guy pitting Mobil 1 against Amsoil. Unofficial, but more real world to me.
Great site for info in oil and other things. Includes air filter tests.
Oil filter study. Deconstructing oil filters and comparing their innards.

 

Everbody has there preferences, I use Valvoline and Wix filters alway will.

I hate Fram and think they are worthless, but there are people who swear by them, so like many things in life you just have to pick a preference and go with it.

i also use k and n and it works kick ***

 

i only use purlator mobil 1 or amsoil filters with either mobil 1 or amsoil oil in my gas cars

 

Motorcraft filters and Castrol GTX for me.

 

You really can't go wrong with Motorcraft oil and filters, especially since both are stocked in Wal-Mart.

Truth be told, most oils these days are pretty good.

 

truth be told most oils, just like gasoline, are made at one of maybe 3-5 rifineries. lots of companies share products so it doesnt matter. make sure the oil has the current and best ratings recommened for ur engine.

IMO, to have a true oil filter test one would need to have several oil filters from a set of changes (say 3 of the same filters in a row) and have the oil and filter media tested at an oil analysis lab. that should show which filters the best.

 

Motocraft is all I use for oil and filters. Every once in a while I might use wolf's head...

 

Most conventional oils you mean?

 

its my believing (probaly not true) that most syns are only made from a few different people as well. just relabeled.

 

I use Mobile 1 oil and filters so its just prefrance as long as you change your oil you should be good!

 

Thanks guys I'll go with the motorcraft filter, what we use in the mustang. And what ever synthetic advance has in stock, for the weight 10W-30?

 

i use SuperTech syn for the ranger and xploder ($11 for a 5 qt jug). over on BISOG.com they give it good reviews and it seems like one of the best guys for the buck IMO. i also run ST dino 10W30 in my F150 for years and havent had any problems.

 

Well I know that police cars use el cheapo stuff. For more than 5000 miles and those engines are RAN hard. SO Other than that I got nothing as for what is best. But I do believe that optikal has a point.

Mobil 1 & Motorcraft filters

 

I use Amsoil Series 2000 0w30 in my truck. I use the "Ea" series Amsoil filters and change the filters every 10k and the oil once a year (about 20k). Oil testing shows the oil is holding up but I change it every year whether it needs it or not.

 

I hope you meant 10w30 :)

 

Nope. 0w30 is not a typo -- that's the rating. My truck is supposed to use 5w20 but I don't like that stuff.

This oil does very well in my truck.

 

omfg, j-dawg-griggs is back =-O

 

yup :)
i will always use both motorcraft oils and filters, if ford puts there name on it, it must be good. plus its tri-syn & cheap.

 

5W30 syn Mobil 1

 

I just switched over to Amsoil (5w-30 w/ EAO15 filter) in my truck, I did the engine flush and what not then put the Amsoil in. So far milage seems a little better, it will take a couple tanks to notice that, but all is good
