Yes, Mobil and Castrol can not agree on how to make a synthetic oil.
Their products are vastly different. Also vastly different additive
packages. But their refined oils are also different. Everybody's oils
are different.
IMO it is a mistake to ask, "Should I use synthetic?" The mistake is
lumping all synthetics in the same pile. The mistake is in assuming all
synthetics might be equal, or that all synthetics are superior. Or as
one motorcycle aftermarket specialist claims, "synthetics are inferior."
Focusing on base stocks or additive packages is myopia. What matters is
the end result. Mobil-1 works for me. For example my 8 year old
Kawasaki-engined John Deere 21" push mower has always had Mobil-1 15W-50
and still has 140 psi compression.

30 years ago this might have been an issue requiring really awful "break
in oil" as many were trying to solve engine life issues with super hard
rings. If you can find an old JC Whitney catalog you'll see Good,
Better, and Best, replacement rings. Marketing focused heavily on
"harder is longer life, therefore better." Everybody had a hard time
making the cylinder and rings conform to each other so the "solution"
was initial accelerated wear on rebuild. The super hard rings were hard
to seat no matter what oil you used. About this time synthetic oils
started making their presence known on the market. Suspect the same
marketing geniuses who pushed "whiter teeth" leveraged the hard ring
seating problem with FUD and forever etched into the psyche the myth of
the synthetic lubricant which is so good your engine won't break in.
The reason there is so much debate is that its very hard for mere
consumers to tell the difference between one oil and another. This is
compounded by the FTC preventing manufacturers from claiming their oil
is better than the competition, or from publishing tests making that
claim. The best they can do is argue additive content, extended
temperature, or "protect in ways other oils can not." The Syntec
commercial where engines were drained and run to failure could not name
the competition's products due to the FTC, not because of fear of
lawsuits from the competition.
