me: mobil 1 'synthetic' (blend) 5w-30 with mobil 1 filter
it seems (and anyone correct me if i'm wrong in my assumptions), that the higher performance true synthetic oils (eneos, amsoil, redline, royal purple) are meant mostly for racing applications. my guess, the blend potion of the lesser 'synthetics' is used to stabilize the oil, to prevent premature breakdown.
mobile 1 seems to have great consumer support, meaning the product is going to be widely applicable, and very stable for all those applications. that would be the upside to a popular product, it seems to be taylored to a wide cross-section of the market (from daily driver tuners, to high end luxury, to jalopies (although who'd waste the money on mobile 1 on a '79 junker)).
for the price, i'm gonna keep using mobile 1, but if i ever build a race car, i'd probably use redline, amsoil, eneos, or RP.
other considerations when chosing oil that were mentioned in this thread:
weather: san antonio is usually 85+ degrees (for about 8-9 months of the year), then 'cold' for the other 3-4 months (it freezes here maybe once or twice a year)
driving style: hard and heavy. i just blew my auto transmission, need i say more?
miles/year: 13-16k miles annually.
