Motorcraft 5W-30 in a 2002 Exploder

[Whimsey]

My wife has a 2002 Ford Exploder with the 4.0L SOHC motor. She has taken it faithfully to the Ford dealer for service since new. They do use the Motorcraft 5w30 SL oil and FL 820S oil filter. The first oil change was @ 2,000 miles the second @ 5,000 on the odometer and approximately every 5,000 odometer reading there after. At this analysis the oil was used for 4,910 miles and the total mileage on the Exploder was 25,340. No oil was used or added.
Blackstone did the analysis. I asked for the "Dyson" package, hopefully I'll get it.

In this case I'm not even going to list the universal averages because some of them just don't make sense. I'll let our esteemed panel of judges determine what they think is "normal" for this oil and usage. And remember I have no intention of running any oil further than the 5,000 mile scheduled oil change interval.

ALUMINUM- 8
CHROMIUM- 1
IRON- 19
COPPER- 7
LEAD- 1
TIN- 3
MOLYBDENUM- 1
NICKEL- 1
MANGANESE- 1
SILVER- 0
TITANIUM 0
POTASSIUM- 1
BORON- 3
SILICON- 14
SODIUM- 2
CALCIUM- 2154
MAGNESIUM- 16
PHOSPHORUS- 793
ZINC- 1001
BARIUM 0
SUS VISCOSITY 56.3/FLASHPOINT 405/%FUEL WATER 0.0/ INSOLUBLES .4

TBN 1.8

Her driving is 30% stop and go on the highway 30% normal highway and 40% mixed local driving. This interval ran from 3/6 to 7/10. Which included cold snowy conditions and hot temps. As a side note the airfilter was changed @ the dealer @ 15,000 miles. Purely as a profit item, not that it needed it.

Let the artillery barrage begin!

Just one question (well, two actually):

Your dealer uses 5w30? Isn't 5w20 what Ford requires for this engine?

And how often does an Exploder explode?

Only once!

The lead number is very impressive, but the high iron is not. It could be normal for this engine though. Oil has thinned out to 9.1cst, so it's now 5w20 anyways.

Gman-II, I believe the 4.0L OHC V6 in the Explorer and Ranger and also the Focus SVT 2.0L ZETEC require 5w30.

Certainly a very O.K. number. Looks like ford either makes its own 20 w t. oil even if you don't put it in.

I would be inclined to use the 10w30 wt. at least in summertime. Moly also would be nice, but with these numbers on the lead it may not be necessarily. I wonder what they use instead of boron or moly that apparently works pretty good on the bearings-and its even a 20 wt.

Too bad we can't tell from the TBN if the oil is shot

. But with it being a 20 wt-I guess it is.

You are correct Sincity. My 2002 Explorer Sport Trac with the 4.0 SOHC calls for 5W30. -Joe

Al, I think under the new system that Blackstone uses, a TBN of 1 is the oil at the end of it's life. Overall I don't think that this oil did bad for what was expected of it. Patman ironically the iron of 19 was what Blackstone "average" was.

Very good report Whimsey. The oil did thin out a little but look at the excellent bearing protection. The iron might be from some of the cold weather driving earlier in the oil run. It is improtant to remember that this is a Conoco hydoclear oil. Motorcraft oil is producing outstanding wear numbers in the new 5w-20 oil and also with heavier weight oil. I am runing Motorcraft 10w-40 now and hope to have good results.

 

[MNgopher]

For a dino oil at nearly 5000 miles it did just fine. Sure it sheared in 5w20 land (barely under 9.3 cst according to my conversion), but the wear numbers show nothing out of the ordinary.

I wouldn't have any problems with this routine using this oil, IMHO.

FYI, yes, the 4.0 SOHC is one of the "exceptions" to the 5w20 edict from Ford.

 

[metroplex]

That's surpising - Exploders usually aren't driven as hard as 4.6/5.4 V8s and V10 trucks which are supposed to use water, woops I mean 5W-20.

 

[Whimsey]

Obviously you haven't seen my wife drive!

I wonder if this being a German made motor has anything to do with specking 30 instead of 20 weight oil.

I think this report is exceptional! Very low wear numbers for this engine.

I am continually impressed by Motorcraft/Conoco oils.

Somebody correct me if I'm wrong, but this is just a SOHC version of the OHV 4.0, which I believe was derived from the old 2.9 V6.

The Porsche designed Ford engine is the 2.5L Duratec used in the Contours. I believe the current 3.0L Duratec is basically a bored out version of the 2.5.

The only similarity between the "old 4.0L OHV" and the new 4.0L SOHC is they are both 4.0L engines. Otherwise they are totally different engines. The old 4.0L OHV developed around 160 HP and the new 4.0L SOHC develops around 210 HP I think. My wife had a 1996 smaller 2 door Explorer with the 4.0L OHV engine. And she now has a heavier 4 door 2002 with the SOHC 4.0L. The 2002 is way faster and more powerful. And the gas mileage is practically the same. The old engine was good but the new SOHC is better

I'm not sure whether they did or not for their SOHC 4.0L German made engine. I still don't know why most newer Ford engines can use 5W-20 yet this engine and the 3.9L V-8 from Lincoln require 5w30

? The 5W-20 seems to be a better constructed oil than the 5w30. It doesn't appear to shear down, while the 5w30 does shear down to 20 weight in many cases. Any ideas?

Are you sure about this. Just because it has more power, doesn't mean it's a different engine. Did they really change that much. As far as I can tell it's basically the old 4.0 redesigned to incorperate OHC heads. The GM 3800 has been redesigned many times, and shares no parts with older engines, but everyone always talks about it being an old engine from the 60s. Are you sure this isn't the case in the Ford 4.0?

[Whimsey]

Ok, I'm totally lost as to your thinking and reasoning. An Overhead Valve engine is one type of engine where as the SOHC engine is a TOTALLY different engine design. The former is a pushrod engine and the latter is an overhead cam engine without pushrods. What am I missing? Where are they related or the same? Just because they are both 4.0L V6's does not make them the same. If you have other information I'd love to hear it.

Is this the Lincoln LS engine? If so, it is really a detuned version of Jaguar's V-8 design and is of completely different design than Ford's other V-8s.
