Pennzoil makes an excellent oil, as does Mobil, which is why I find it curious you felt it necessary to defile it with aftermarket additives
I don't believe that what you are trying to achieve here is within the scope of utility for Used Oil Analysis. You'll likely see some minuscule variance in PPM between the two lubricants, which demonstrates nothing more than both provided adequate performance over the experienced duration. If that was the purpose, then I'd say you succeeded, but that's not what you outlined in the OP with regards to your wager, which could be affected by ambient temperature, dust, driving style...etc.
Defile it? It's engine oil. Not a sacred text.
If you'd honestly like my reasoning for using these additives, I'll type it below.
I've been using MoS2 in every internal combustion engine for as long as I can remember. Knock on wood, I've never had a mechanical failure to speak of. Not even oil seals. I believe the MoS2 has something to do with it. I also use this additive in my air compressor and it is measurably quieter. At worst, it's doing nothing and I'm wasting my money.
This vehicle is the only one I've been adding Motor Oil Saver to. And for one big reason. I recently purchased this vehicle and wanted to make sure the valve stem seals are doing their best at keeping oil where it belongs because this vehicle has the most sensitive catalytic converters I've ever seen. Even a small amount of oil burning from this engine has time and time again caused converter failures on my customers cars. I aim to prevent that by running this additive a couple of times and then maintaining everything with high mileage oil after I stop using it.
As far as it being a completely scientific test, I never said that it was. It's just a bet with a coworker that thinks Pennzoil is the worst oil maker on the planet.
OK, but there are plenty of us on here who have never had a failure, even seals, not using it
I'd likely be inclined to use a high mileage oil like what you used, or Maxlife, for the seal issue, rather than an additive. My inclination is to use an oil as it is blended and tested, rather than altering the chemistry and potentially affecting its performance.
I'll agree with the intention of your wager, I think he's out to lunch too, I just wanted to ensure you were aware of the limitations and purpose of UOA's. Your use of additives also caught my interest, since they have the potential to affect the results.
