Oil changes are going to be cheaper on a Ford Focus where you can run Mobil Super 5000 5w-20 (it meets ford specs) than a Honda Civic where you have to buy a synthetic 0w-20.

I have been using M1 0-20AFE in both Fords for several years. Both engines perform very well and I wouldn't use anything else.

It's basically just hopes and dreams in a bottle. No manufacturer ever recommends any type of snake oil and the only reason it's sold is because people buy it.

If it ain't broke, don't fix it. I don't know why everyone always thinks they know more than the engineers who designed the cars.

Mariner?

Didn't he say Mountaineer?

I think of it as "clean sludge"....LOL, just kidding, there must be a useful purpose for it...I just can't think of one right now.

Any would work, 0w-20 is what I would personally use all year round.

Yes, 0w-20 works just fine in the summer...why people still think you have to replace it with 5w-20 in the summer is beyond me.

+1 the 5w does nothing to change anything just because it's warm outside.

Use the 0w20!


This is the proper answer.

+1

I run 5w20 currently but the next change I'll be going to 0w20.

Same here; I have used M1 0W-20 AFE and M1 0W-20 EP in my FX4 (which has the larger version of the 4.6L) and it worked flawlessly. I would use the 0W-20 without thinking twice.

Any of those viscosities on your shelf will work. Don't even worry about it.

^this.

You could use any of the grades you've named without any harm.
The Ford cammer originally had 5W-30 recommended for it, so I'd seriously doubt that it would do any harm to use it.
Engines just don't seem to be all that sensitive to differing grades of oil and it's not like you'd be using 15W-50.
Does anyone else recall a now departed member from Kentucky, IIRC, who used M1 15W-50 in everything including small-motor Asian cars and had nothing but good results to report?

 

[dave1251]

Use the grade you have to most of first.
Your son's 4.6 will not care. I had a fleet of 5.4's that used 15W40 year round.

 

[ThirdeYe]

Just go with the 0w-20 and call it a day.

 

[chiefsfan1]

Go with the 0w20.

 

[barkingspider]

Don't buy oil. Use your stash, doesn't matter which weight. Ok to mix if u want. Your car will run fine

 

[Dallas69]

Dont you know that mixing is now frowned upon by some here.
But not me,so mix away.
