Wow - awesome blend!

I guess it must have been the M1 top up that kept the wear so low

Sb = 2

Quite a concoction...but quite a performance as well.

Thanks Mark. Could antimony be anything other than an additive?

Forgot to mention uoa was provided by Butler. It was my first time using them and I think its quite a deal at $12.

I was wondering if we could get an explanation of the ferrous debris and the anti-wear values.

This is my friends volvo. He likes the 50/50 mix

but it seems to work. It's mainly a city driven car, and he does not drive slow, at all. I think there was another guy on here who gets great results in his t-5 powered volvo too.

This car has lost a small amount of coolant over the last few months. I thought it was probably a bubble that worked its way out because he had changed the coolant pretty recently, but there is a small amount of k and na present. I was wondering what everyone's thoughts on that are. This was a winter interval and the roads are salted here.

Amazing results! And with K&N air filter too! Looks almost like a VOA! How many months was this oil in service?

 

[Santo Fontana]

I will ask him but it is something like 8 months.

 

[Patman]

Very nice results! Also more proof that the K&N air filter can work in some applications. It's working well in mine, and even better in this one!

The Amsoil 5w-40 will work at least as well as this blend and is $2.00/quart less expensive. It also meets the latest Volvo factory fill oil requirements in case your engine is under warranty.

There is NO reason to mix these two oils unless you are simply using up old stock....

For an explanation of the anti-wear value, here is Stinky Peterson's explanation:

"It's the ZDDP level as measured on FTIR. It starts out negative and becomes more so as it is depleted. I was told at around -o.3 it is pretty well used up. This was by the FTIR manufacturer and I have found no other sources."

It is not uncommon to see very low levels of elements that are not expected. Sometime this is due to interference from other elements or it may just be a noisy signal, the spectrum of a sample of used oil is pretty complex. This a is good reason not to get excited when you see a slight change of 1 or 2 ppm as there can be small variations.

As for PQ, it is a measurement of ferrous debris or iron. The advantage this instrument offers is that it is not dependent on particle size. The ICP (which measures iron and the other elements) can only see particles up to about 5 microns and anything bigger is invisible. With the PQ you can put a nut or bolt or gear tooth in the bottle and we will give you a nice high reading. The instrument itself is a magnetometer so it doesn't matter if the oil is dark, has water, or severely contaminated.

TS I agree with you that the 5W-40 is less expensive....I have no quantifiable data that says it will work as well or better, though. I am not generally advocating mixing oils, but gosh durn it - it DOES work sometime!

Thanks for the explanation, what is an average PQ value?

Also, what does PQ stand for?

Pablo,

I've seen enough data to suggest that the 5w-40 is significantly better than the regular Amsoil 10w-40 for gas engines and light duty, automotive diesels. So that's what I'm selling locally for these applications, along with the obvious replacement market for the high end Euro motors....

The 5w-40 has the required fuel efficiency to meet the MB 229.5 spec, while the 10w-40 only meets the older 229.1 and 229.3 specifications. So it is a superior additive chemistry and uses an oil soluble FM; most likely some sort of ester.
