Amsoil Dual Bypass 10-11K mile Analysis

[tanman_2006]

I tried to attach the Document but if it didn't work here are the worry points:

Severity-2

Magnesium-57

Vis 100c- 17.6

Silicon- 26

I was told silicon could be from a bad air filter seal (what a suprise from a box filter :rolleyes5: )

What is the magnesium from?

I am running Shell Rotella T 15w40, I changed the primary filter @ 5,000.

I am changing my oil, I just want thoughts.

Here are the elements from my UOA vendor and their most likely source.

[FONT=Arial,Helvetica,Geneva,Sans-serif]Elements[/FONT][FONT=Arial,Helvetica,Geneva,Sans-serif] are quantified in the oil at part per million levels (PPM). This list shows the most common sources of the elements in a gasoline or diesel engine oil. [/FONT]

[FONT=Arial,Helvetica,Geneva,Sans-serif]Aluminum: Pistons, bearings, cases (heads & blocks).
Chromium: Rings, a trace element in steel.
Iron: Cylinders, rotating shafts, the valve train, and any steel part sharing the oil.
Copper : Brass or bronze parts, copper bushings, bearings, oil coolers, also an additive in some gasoline engine oils.
Lead: Bearings.
Tin : Bearings, bronze parts, piston coatings.
Molybdenum: Anti-wear additive, coating on some new rings
(washes off as break-in occurs).
Nickel : Trace element in steel.
Manganese: Trace element, additive in gasoline.
Silver: Trace element.
Titanium: Trace element.
Potassium: Antifreeze inhibitor, additive in some oil types.
Boron: Detergent/dispersant additive, antifreeze inhibitors.
Silicon : Airborne dirt, sealers, gaskets, antifreeze inhibitors.
Sodium: Antifreeze inhibitors, additive in some gasoline engine oils.
Calcium : Detergent/dispersant additive.
Magnesium: Detergent/dispersant additive.
Phosphorus: Anti-wear additive.
Zinc : Anti-wear additive.
Barium: Detergent/dispersant additive.[/FONT]

Some oils used to use Mg as an additive. Blocks also have Mg in them.

 

[JMJNet]

What kind of air filter are you using?

 

[SfcJones]

as far as the silicon is concerned, look at the filter for any damage or the housing itself.

 

[tanman_2006]

Its a WIX filter, I have always had good luck with them but my last one was deformed when I pulled it out to change.

I am hoping the Mg isn't from the block. Does shell or Amsoil Synthetic 5w40 have Mg?

I run a nondetergent 30w and 2 cycle additive rotate through both or mix, first time I bought 30w it wasn't nondetergent though OOPS!

Well your Mg content wasnt really high, so its probably from the 2-stroke or regular 30W, and blowby could put it in oil. how much do you use per gallon?

A compression test may be more telling how it got there, or maybe you can see there is blowby out the oil fill when truck is running warm. I get a lot of blowby, so I wonder what my oil analysis would show

Shell doesnt use much Mg in diesel oils which is why it was flagged as odd, Amsoil I think stopped using Mg additives, Ashton (wrecker the oil geek) would know better.

Viscosity was high, may have been cleaning a lot of deposits that became trapped in the oil

I use 1 quart per 26 gallon but I do miss sometimes.

My truck has some blow by but is doesn't seem bad and only uses a quart every 5,000 miles. I have been adding Amsoil 5w40 when it gets low. I went through Lube Specialist I think it was Greg and he is the one that said the airfilter seal can be the cause of Silicon.

So all in all my oil really isn't that bad? Could I keep going?

 

[buddy]

It was time to change it. It is the viscosity reading that is telling. It is higher than normal, which means its collected a lot of debris, or been overheated, or you need a better filter, or you arent getting enough bypass filtering, how is the bypass system installed?

 

[buddy]

You know they flagged your viscosity as abnormal, but I dont think thats very high too. This is where you need to ask the Oil Geek. Since Amsoil I believe has naturally higher viscosity or something like that, so adding that could result in the higher number.

I will go ahead and change it.

It hasn't been overheated hardly at all it hit 220 once or twice thats all, I wouldn't doubt the oil has collected debris. My kit is on the frame rail by the T-Bars for now ( bent the bracket off road since it is below the frame) I am going to relocate the set up to behind the T-Case so it doesn't hang. The kit has the large 2wd factory type filter and a 2 micron bypass through a restricor orfice.

Your vis at 100C is well into the 50 weight range. Amsoil uses the same SAE viscosity rating guidelines for kinematic viscosity as everyone else. Generally, overheating a multi vis oil will cause a drop in Kinematic Vis numbers due to shearing down of viscosity improvers.

Have you switched from or topped off with a different oil?
AME (Amsoil 15w-40 Diesel and Marine) generally has a Mg number of less than 20 in the UOAs I've seen. Delo on the other hand I've seen over 100. That's why I'm asking if you are mixing oils or maybe not getting a good drain between changes.

Silicon is almost always from the air side, some oils use it as an antifoaming agent, but not at those levels.

You could have some strange effects from running weird things in your fuel. I run fuel additive in fuel, trans fluid in the trans, etc. I'm weird like that.

A 2 overall is no reason to go and get excited. Sample again in 5-6k miles IMHO.

Hope this helps.

Thanks for the input, I'm glad to hear from an expert.

I topped off with Amsoil 5w40 Synthetic only 2 quarts at the most. Original fill up was 15w40 Shell Rotella T (Dino Juice)

I am running the 2 stroke and NON Detergent 30w (1/2 quart of each) in my fuel due to a bad Injection Pump and worn Injectors, less injector knock and my SES Light comes on less. The regular 30w was an accident.

Ive gone about another 3K on it since the sample.

 

[SfcJones]

I would never change weight....I would stay with 15W40 and the same brand, That way you can compare apples with apples

 

[tanman_2006]

Lol a little late for that. I just look at it as converting to Synthetic slowly. I talked Greg @ Lubrication Specialist and he said there aren't any problems with doing it (besides the oil analysis :rolleyes5.
