VOA of AMSOIL premium protection 10w40.

So is calcium one of the ones that can be bad for the cat-converters or is it bad in a GDI engine for other reasons? What about Moly? Is it one to avoid also with GDIs? I know some oils tout the fact "high Moly."

Calcium is only a detriment to certain GDI engines (more so TGDI) in terms of LSPI. It's just a bit too reactive. The sulfur can be harmful to cats, but it would take quite a bit to have an effect and the same would apply to any other additive containing sulfur.

Calcium sulfonate's root is a calcium carbonate salt (chalk). Take some chalk and scuff a bunch of it in a small area on the sidewalk, porch, or wherever. Take a glass, or something with a flat bottom to it, and slide it across the deposited chalk layer. You'll notice how the chalk fills in the gaps of the surface and forms a rather slick layer. This is weak compared to the MoS2 deposited by MoDTC, little more than enough to cancel our ZDDP's friction increase, but it's still something. The downside is, since that CaCO3 deposit is still basic, it can neutralize ZDDP's acidic nature in high concentrations thus ZDDP increasing helps counter that to maintain a balance. ZDDP should always be the dominant additive.

So this is not a HDEO, more a light duty? Could this be used also in Kubota engines?

Both HDEO and flat tappet engines.

Possibly older roller rocker engines as well that’s built and isn’t direct injection (just regularly fuel injected) but I’m trying to get more information on that.

Ima run it in my ls lq4 to see how it does and do a used oil analysis on it then later amsoil z rod, euro fs, boosted xl, and signature series to do testing on 5k mile oci intervals to see how it goes.

I dont see it being an issue in the kubota however I can message amsoil to see if it’ll be suitable. Is that kubota a diesel?

Should be fine

I have many Amish mills in my neighborhood and many are running Amsoil 10-40 AMO in their Kubota diesel engines, as well as in most Honda small engines.

Been curious about this oil for a while and haven’t seen any recent VOAs on it. Decided to do one to see if it would be great for my application.
Would have liked to see more moly, higher oxidation value, and around 300 less zinc. I’m sure this oil would do phenomenal in a built diesel application or older flat tapped engine.

(The 04 Denali I have isn’t direct injection. Just fuel injection)

Added to the VOA Database.

Added to the VOA Database.

I’ll have 4 more to add soon

 

[Jw95]

4 more samples ready. I’ll ship them out Saturday.

So a question:

Are these virgin or used? If virgin, what do you hope to learn past what Amsoil lists on their site?

If used, Why are they all listed as the same vehicle with the same mileage?

All virgin tests for these. I haven’t seen a voa on 4 amsoil products I’ve been curious about or none showing the oxidation value or recent as well depending on which product.

Used will show the exact mileage. I’ll test all of them in the same vehicle for these 2 ocis at a time so the second sample has no cross contamination.
Mileage is shown all at 420k because that’s just documentation of about how many miles are on the truck at the time I sent off the VOAs.

The daily’s however. The 2015 Honda accord 2.4L (hers) and 2010 ford fusion 3.0 (mine) I’ll be testing 2 ocis of amsoil ss and xl in the correct viscosity grade for those vehicles in daily driver applications and do testing on off the shelf synthetics to compare them to at the same mileage. Then do long oci intervals on xl and ss for data to show as well as for my curiosity.

Could you please explain, scientifically, how a $50 oil analysis would allow you to decide where this oil was deficient, when Amsoil probably dropped at least 5 figures to determine this was the formula that would best protect their name by doing what it’s supposed to? I’d love to know what methods you used to determine these characteristics.

I can explain it the best I can with what I know so far.
For the analysis part we can see the chemistry of the oil with what it has, how much of it, and etc to help determine if that’s the best formula for your goals and application.

Other companies as well as amsoil spends large sums money on both testing and marketing. As we know Mobil 1 fs and esp are both euro spec oils however in used analysis testing we see how well those oils do in domestic applications and many cases better than the api oils that was formulated for that domestic application.

We can take the knowledge of what we have learned and either know it’s not gonna work well or will great. We can also make a knowledgeable hypothesis on how the oil will do from the voa then test it with data in a uoa to see how well or poor it does.

Hear say as well on products from people using as example the premium protection 10w40 with great results in LS applications so I wanted to see a recent voa as well as test the product for myself to gather data to see if it could also be of best benefit for me as well.

I know driven ls 30 and dt 40 do phenomenal in ls applications. I’m also trying to find an oil from amsoil that will provide me with the best results running an amsoil product. Also trial and error incase something could possibly work better.

I apologize if this answer isn’t up to par with what you’re looking for. I’m just getting into doing my own testing rather than just reading results from others. It’s a curiousity thing as well on my end.

 

[burbguy82]

with what I know so far

On this subject...I think you may find, that the more you learn, the less you know. I did.

Try reading up on some of the threads about the validity of oil analysis............you will find many arguments. But, an oil test really does not test the oil, at least in the capacity that it matters to us...if anything it shows a picture of the wear and condition of the engine. That is the real function.

Think of a general blood test. Is it a test on how well your blood performs???? Or is it a test used to see issues in the rest of the body? Same thing.

An investment to gain knowledge always gets a return.

Yet whenever a VOA is posted here, people still look at them with interest and thank the person who posted them. I put them in a database and people thank me for doing that. It gets thousands of views.

It is good to understand what a VOA is capable of showing and what it is not capable of. But sometimes we know its limit and do it anyway out of curiosity, fun, or hobby. People spend thousands of dollars on other hobbies. This one only costs $40 a pop.

You'd be the first to be able to do that. Back to your comment about spending huge sums of money on testing, well that is for a reason. It is not possible to do the things you're claiming through a cheap spectrographic analysis, there are far too many uncontrolled variables to make it possible.

Comparative performance analysis between oils is complicated, expensive and is designed to eliminate any variable besides the performance of the oil. It's not easy. If those companies you reference could do that for $35 they would. The actual performance difference between any fully formulated oil is actually pretty deep into the noise in everyday driving. You cannot tease it out with a UOA.

What's the specific molybdenum compound being used, and what is an effective treatment rate?

A spectrographic analysis does not determine compounds or "additives", only decomposed molecules. Without knowing what the specific additives are you can't make comparisons like this. Just because it has some PPM of "moly" that doesn't tell you what you need to know.

Definitely. I’ve had a few people tell me that. It can still however help get you in the right direction tho as well. Lake speed jr shows that in his videos.

There’s none in this formula and after reading more on the amsoil website I now see why.

What is your interpretation? Wet Clutch?

 

[Jw95]

What is your interpretation? Wet Clutch?

Wet clutches need friction. I didn’t see the part of this oil also being wet clutch applications therefore it makes sense why it doesn’t have any addictives to reduce friction. I’ll do better for now on looking into more details on products.
