Amsoil didn't do any better

That must be quite the VOA to show silicone.

I believe it is pretty common. Same with aluminum

Al was high in the Amsoil run. Wish I had done a VOA of it, some of it was probably already there in the oil.

Okay folks, just changed the oil, hpl premium plus 0w16, fram endurance, 6000 mile OCI. Wish me luck, I don't want anything in my filter lol.
HPL surely looks different and smells different. But my engine doesn't sound like it noticed any difference lol

Not bad for 15 miles

I do not know of any spectrographic analysis that shows silicone.

Is this due to the oil?

Silicon, not Silicone. You are just parroting my typo.

Is this due to the oil?

Yes. My best mpg has been with Toyota 0w16.

No. I’m illustrating your lack of knowledge and what you’re claiming in regards to conclusions you’re drawing.

Never under any circumstances can you ascertain in everyday driving that an observed fuel economy change is due to an oil. This is deep into the noise. Many factors influence fuel consumption in this kind of an uncontrolled environment. For one thing the gasoline itself varies in BTU content, one study showed a 4% variance in energy density even at the same gas station - and this is separate from seasonal variations in formulation. There are tens of similar and equally significant variables that also influence your measurement.

Good morning. I guess all these oils are good. Amsoil just has a higher TBN, not by much though. First three oils are Mobil 1 AFE, Toyota, and Pennzoil Platinum. I think Pennzoil is the best deal of all four. What do you guys say?

The oils all worked. Use the brand your car seems to "like".
