As they say on race day commercials: "More ASE certified Master
Mechanics choose VALVOLINE for their own cars." Maybe there's something
to that. I run Castrol GTX in the SAAB. It is the engine oil of choice
according to most SAAB afficianados I have consulted. I'm not sure if I
can afford the extra dough for synthetic oil changes in the Midget.
The biggest concern I have is with unfiltered air entering the engine via
the oil filler cap breather. If this vent is left unfiltered, I would be
foolish to extend my drain intervals. Anyone have an easy way to modify
my valve cover for a sealed cap and a separate (K&N?) vent filter? What
about an affordable valve cover that already has these features?
Building in longevity (I hope),
