Fair enough, and I don't think you should.
Mobile 1 is clearly superior to conventional oils, and anyone
who uses and changes it within manufacturer's recommended
intervals should happily bask in the warm glow of an
obsessively pampered automobile.
I am talking geeky overkill here,
so the non-obsessed should
skip to the next message.
Amsoil tweaks my obsessions with its better performance
in the wear test--a 33% smaller wear scar in the four ball test.
Does this really translate into longer engine life? I don't know.
It comes down to the old cost-benefit tradeoff-- Costco doesn't
carry Mobil 1 0-20, so it would cost me about $5/quart all told,
versus $6/qt delivered for the Amsoil 5W-20 (the XL-7500) .
It just comes down to each individual to decide if the extra $1/quart
is worth it to him or her. If anyone has an insights into the wear
results' validity and significance, please share.
In the meantime, those using synthetic oil should definitely
not lose any sleep.
