Curiously Phos/Zinc have identical values - Blackstone typo/error? Car has a slight oil leak that may have contributed to the additional consumptoin. Also, leak seems to be from the headgasket so I need to monitor anti-freeze closely ... so far so good! Either way, it seems the new M1 TDT (with supersyn) is as good a fit for this engine as the previous iteration. I'll keep posting these as there are not all that many SAAB reports on the board.

That's a great result. Did you have some sort of mechanical problems during those GC runs? I'm pretty convinced that a 5W-40 is the only way to go on the 2.3 Saabs. jeff
