Poll: Synthetic/Conventional/Blend

Run all the polls you want. Start all the new threads re-hashing old news all you want.
My impression is operators of this website would rather there be more threads and more content, than less.

I run napa full synthetic in modern fuel injected cars, with more extended drain intervals but my cars aren't super new.
Napa pure syn is very likely just high grade crude qualifying as synthetic because it meets certain levels of uniformity and purity.
If I had a quite new modern car or engine, I would run mobile or another premium synthetic.

Carbureted cars pollute / ruin the oil with fuel fairly quickly so I tend to run good quality conventional with a bit of zddp as of late and just change it at 3K.
