For long time drivers, and in my own case, a service man of over 2000 vehicles in the grubby oil pit... I am obsessed with oil strong enough. I despise spam, but I do like facts in my email. Castrol syntec has helped keep a 23 year old boxer squezing out the "hho killer" and I can drive anywhere to this day on the original build because of it. Adding some things like todays 10% ethanol fuel (and worse) , and external ducting to that of modern cars (pcv type stuff), the low temps make sythetic dead in the spring, all versions. There is another oil called castrol edge, claiming to utilize what today is burning,anyone tried it?
I am going to, for the sake of a rebate, and the facts of low temps, I can go back to 10w 30 instead of the water grade my ea82 makes everything else on the trochoid oil pump. This should be applicable to subaru boxers. The thermal disspiation of even the biggest turbo'd EJ is different than inlines and a majority of exact oils.
The stuff I have in bold sold me. Its at wikipedia, not an oil website.

A more specific type of olefin is a poly-alpha-olefin (or poly-α-olefin, sometimes abbreviated as PAO), a polymer made by polymerizing an alpha-olefin. An alpha-olefin (or α-olefin) is an alkene where the carbon-carbon double bond starts at the α-carbon atom, i.e. the double bond is between the #1 and #2 carbons in the molecule. Common alpha-olefins used as co-monomers to give a polymer alkyl branching groups are similar to 1-hexene or may be longer (see chemical structure below).1-hexene, an example of an alpha-olefin
Many poly-alpha-olefins have flexible alkyl branching groups on every other carbon of their polymer backbone chain. These alkyl groups, which can shape themselves in numerous conformations, make it very difficult for the polymer molecules to line themselves up side-by-side in an orderly way. Therefore, many poly-alpha-olefins do not crystallize or solidify easily and are able to remain oily, viscous liquids even at lower temperatures. Low molecular weight poly-alpha-olefins are useful as synthetic lubricants such as synthetic motor oils for vehicles used in a wide temperature range.
Even polyethylenes copolymerized with a small amount of alpha-olefins (such as 1-hexene, 1-octene, or longer) are more flexible than simple straight chain high density polyethylene, which has no branching. The methyl branch groups on a polypropylene polymer are not long enough to make typical commercial polypropylene more flexible than polyethylene.
