I'm using Amsoil 10-30 in the wife's 4ks (1.8). I bought a 4kcsq (2.2) in
June, drove it for 1500 miles (didn't use a drop, had Amalie in it, I
think), then switched to 0-30 (which is ~$2 more per quart). Now it
consumes/leaks a quart every ~2000 miles :-( I'm considering switching back
to 10-30, which has lower volatility (the wife's car stays full for ~20k
miles between changes, 'cep when I change the filter).
The 10-30 has a pour-point of -75F which should be good enough for here in
southern NH (-18F minimum in my five years here). The 5-30 pp is -76F, but
the high-temp performance is much lower than the 10-30--I don't see any use
for the 5-30. The 0-30 has an extended drain interval of 30k miles, while
the 5-30 and 10-30 are 25k miles; neither applies to turbo cars, where
Amsoil recommends not exceeding the manuf's specified drain interval.

I have an Amsoil foam filter, but no turbo and stock exhaust. It seems to
work fine, but ymmv.

I don't have any data, but I would guess the bypass filter won't help you
much. The Amsoil filters are the best available and will be changed, with
the oil, every 7500 miles anyway (due to turbo). The bypass setup is about
$60 (?) and time (and space) for installation, plus another quart and
filter at each change.

I don't try for extended drain intervals, so I don't do analysis.
