How many changes so far? Iron looks high but it's new.

Good to see it's a moly batch.

I haven't paid enough attention to SS analyses... is SS always thinning out like TS did? What lab was this? Of course I have to ask about air & oil filters.

This is my 2nd change. The first one was drained around 1000 miles. I'm just using stock air filter, and Motorcraft 820S oil filter.

Blackstone Labs did the analysis.

The copper had me a bit concerned, but not sure how common that is for a new engine.

I think M1 starts out thin, so I don't know if it thinned out that much. It's within the proper range.

 

[OneQuartLow]

I didn't think the copper was high this new. Not for the 2nd change. Someone here will know that engine better than myself.

Seems a little thin. Starts out around 58-59, but then I'm using a ruler over from their published 9.7 cSt@100C. Might also be a lab thing. Or that I'm still watching for it after seeing drops with my trisyn.

What do others use to convert between viscosity standards? I have Schaeffer's grade systems table but rulers are a pain. Any web calculators out there?

[Patman]

That viscosity converts to 9.3cst at 100c. It's now 5w20 oil. I thought SuperSyn had the thinning problem licked too.

 

[Patman]

By the way, what is up with all the copper in new engines lately? Are they using old pennies to build these engines?

They might have switched to a floating wrist pin on some of these newer motors. The small end of the rod would have a bushing that could show as a wear metal.Cranks not true running and wearing in the thrust surface of the main bearings ect.

There is another 4.0 here with Motorcraft oil and about 20k or more on the motor,the analysis is double good for the driving conditions

I still think the Supersyn has been tweeked recently,yep,yep I do

doesn't M1 start at 9.3?

also, why is the silicon so high?

Probably a combination of the oil pan seal that sits in a reciever groove that may or may not have Si content and the pistons being Hyperuetectic having a higher Si content than some pistons of yester year.

Oil analysis is not exactly acurate to all that maybe going on inside a motor,,,great for oxidation numbers,TBN and solids plus some more tidbits though

It's a new motor, so the solicon is probably from the gaskets.

Other than the thinning out. I'd be OK with this. Magnesium seems low- Should be in the 300 range I believe

. More evidence that 10W-30 is a better choice IMHO.

 

[Giles]

Has M1 SS 10w30 held it's viscosity better than 5w30? I know they show about the same viscosity at temperature on the specs. I have both 5w30 and 10w30 in the garage, and need to decide which to use for the next drain. I'm tempted to use 10w30, but then again it would be nice to get a trend on the engine with no changes in filter or oil.

 

[Patman]

Mobil 1 SuperSyn 5w30 starts out around 9.7 cst according to Mobil 1, some virgin analysis results we've seen show it around 10.4 cst.

Actually so far both of these viscosities have shown to hold up very well, this really is the only 5w30 report so far on SuperSyn that showed it thinning out so much. All the other 5w30 and 10w30 reports we've seen here show it holding viscosity very well.

Here's another analysis from a Ford Explorer 4.0L using Mobil 1 supersyn. 5w30.
Mine's a '94 with 105,000 miles.
K&N air filter and Wix oil filter.
3,500 miles on this sample I just received results on from Blackstone.

mcmech, your results look good. You should start your own thread and others will be more likely to provide feedback. I have a '91 Explorer with fewer miles, but it didn't have nearly as good of numbers as yours.

 

[mcmech]

My results may be somewhat deceiving.
I bought the Explorer last November w/100K on it from the original owner.
He said he had always used 10w30 dino oil and changed it every 3,000.
This is the first synthetic the truck has seen so it may be more of a reflection of whatever brand of oil he used before this....I don't know.

 

[MolaKule]

My son-in-law uses M 1 SS 10W30 in their Explorer and have had no problems.

We will sample some time this spring and report.

 

[TooSlick]

mcmech,

Your analysis numbers are excellent ...I'd step out to a 5000 oil/filter change interval under these conditions w/ Mobil 1. Very low valvetrain and bearing wear on this motor - even with the K & N.

Interesting how the wear numbers look better. My guess is the makeup oil diluted the concentration of contaminates, although, it went down significantly on the iron so it looks like lab error on either lab, or both.
