Say, what's all this "Service SJ" stuff anyway?
Mobil 1 seems to be the most popular synthetic (at least it gets mentioned
the most on this list, & on A4.org). So I trucked over to Kmart to check
prices (all in the $4/qt range). Looking on the back, all the synthetics
say "for service SJ" (or "SJ/CF"). Many of the labels claim equivalence
to other codes, (usually SH)-- but NONE claims to be a replacement for
either SF or SG.
The trouble is, my owner's manual says to use service SF or SG oil. What
the heck do these codes mean anyway? Is there a system to them? Would
SJ include everything from SA to SI?
