VOA of AMSOIL premium protection 10w40.

[Jw95]

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)

the calcium also acts as a friction reducer, without the deposits moly causes. But with that amount of calcium, the zddp concentration has to go up aswell, to keep balance.

Maybe not for GDI, but other stuff should work well with it.

Looks real good. Thank you for the VOA.

No problem

 

[fantastic]

That is high Zn like they claim.

I thought that was boron that acted as both and calcium was just a detergent. I appreciate that tho. And yes sir. All about balance.

With the truck just being regularly fuel injected and not direct injection I may run it and do a uoa on it to see how it does. Then amsoil z rod for intervals next with 2 uoas and go with whichever provides better results. I don’t run long oci intervals in this truck and for its use signature series wouldn’t be best for this application. I do however run signature series in both daily’s for mine and hers. Im gonna start doing 2 oci intervals of each off the shelf synthetic with a uoa then amsoil ss in the daily vehicles to provide more data comparisons with the same mileage. Then extend amsoil ss after with uoa to show it can go longer and with great results. The 2 daily’s for mine is a 2010 ford fusion 3.0 v6 and a 2015 accord 2.4.

Thanks for the VOA

no calcium does it too, that's why magnesium can't replace calcium fully. Most of the boron we see in VOA is likely part of the dispersants. Calcium also helps in greases and transmission/gear oils for anti-wear.

I greatly appreciate that info.

Boron is usually a phosphorylated boron, a multifunctional additive that serves as an ashless antiwear, antiscuff, and friction reducer.

Calcium can also reduce friction, but its primary function is as a detergent.

I think I might run that in my old 6.2 Diesel.......looks like a motorcycle oil? Wet clutch no moly.=no @TiGeo

ashless=good?

The lower the ash the fewer deposits that are left behind.

Oils with low volativity leave fewer deposits behind.

Is volatilty and NOACK the same thing?

The NOACK describes the relative volativity of a lubricant fluid.

 

[burbguy82]

The NOACK describes the relative volativity of a lubricant fluid.

So a low NOACK would correlate to low deposits......I thought this to be so, but some on here do not think that is true. So is is fair to say, all other things being equal, that low NOACK=low deposits?

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."

Ran that in my Suzuki GSX-R 750 when I owned it. Good stuff.

Here are many discussions about LSPI:

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