Subject: Boost gauge, Mobil 1

[superba <superba@pacbell.net>]

Hi Paul,

I won't address the boost gauge, but the weight of oil ought to be dtermined
by the ambient temperatures where you do your driving.  The handbook and
maybe Bentley will recommend different weights of oil for a range of
temperature excursions;  I would then use the appropriate weight of Mobil 1.

HTH.

Cheers!
