Vince

is that calcium, zinc and phosphorous buildup normal?

Yes, it shows the continuing dilution of the original OEM oil.

Vince

are any of those elements out of whack?

Yes, it shows the continuing dilution of the original OEM oil.

Does that go the same for the lead buildup?

I'm sending my first one off to Blackstone in the next couple weeks. Hell, I'm going to be in Fort Wayne for Thanksgiving... I wonder if they have a walk up window :).

No, everything looks real good!
I think some of the wear metals go up and down a bit because of where the sample was taken (like at the first part of the pour VS. the middle or end).
The fuel dilution went way down as soon as I installed Canzoomers Stage One.

Here's a link of what the various readings mean.

Don't know why lead would be treading up though...

Interesting. Fuel = 1.5% My oil constantly smells from fuel. Dealer keeps trying to tell me that they use part synth for the oil changes and that's what the oil smells like.

If there's approximately 7 qts of oil in the system, then 1.5% is about 3.36 oz. That would easily account for the smell of fuel in the oil. It would also account for the poor mileage considering that the fuel probably boils off once the engine is at operating temperature.

Who does your oil testing and how much does it cost?

Considering that out of 7 quarts only 4 gets changed, it makes sense that fuel in the oil would linger beyond changes.

Not sure who RX3+5 is using, but http://www.blackstone-labs.com/ is a popular choice... they'll send you the sample kit for free, and they charge $20 to process it.

I use http://www.blackstone-labs.com .

Using Canzoomers Stage1/2 halved my fuel dilution and decreased my fuel consumption by a little.
