Alan Hamm, I do recall hearing that there was a change in the size of the aux oil reservoir on the 603 engines, that would explain how some cars can take over 8 Qts. Heck I just remembered that Jag XKE I used to drive, it took 12 qts and then some and leaked like sieve too! Bad dream!

FWIW, I buy AMSOIL in the 2.5 Gal container and just add oil until I get it >almost< to the full mark. There is not much left in the jug when I finish so I might be adding close to 8+ qts I guess I'll have to get more scientific next time I do an oil change and measure it out.
