1. there's not many true synthetics out there, regardless of what it
says on the bottle. mobil is the only main stream one.
2. i was running mobil 1 on my 89 civic earlier this year. i was
interested to note that not only did the car perform better, but fuel
economy picked up a little too. in the range of 3% - 5%. that may not
sound like a lot, but if you do the math, you only need just under 3%
for the much greater cost of the oil to pay back in fuel savings. i'm
also pleased to report that there were no issues with oil leaks. i'm
not running it right now because i've recently changed the head gasket
and am still in "flush" mode, but i intend to return to it shortly.
3. castrol is great conventional oil. i've used it for decades with
great results. i occasionally try other oils just for the sake of
experiment, and with the exception of mobil 1, have always been
disappointed.
