lol..those are different ma..
my mum buys them too

hehe..
oh i found this from ek9.org.
this is taken from the ek9 service manual.
Depending on your climate, the best oil for the b16b will be the following:
20 W - 40 - Recommended for climates -10 C to 15 C
20 W - 50 - Recommended for climates between -10 C to 40 C +
5 W - 40 - Recommended for climates between: -30 C or less to 40 C +
10 W - 40 - Recommended for climates between: -20 C to 40 C +
10 W - 30 - Recommended for climates between: -20 C to 30-35 C
5 W - 30 - Recommended for climates between: - 30 C or less to 0 C
Using this information you can't go wrong, I use Motul 10W 40 semi synthetic with no problems at all, I change the oil every 3000 - 5000 km, ALSO I change the gearbox oil when I do this, this is very important. I do this because I use my car for daily drive + track days.
