1999 forester s turbo
Is the oil filter for the auto box the same as the standard oil filter? And where do you top it up? I'm assuming through the dipstick hole. If thats the case, how much oil does it require.
The AT Filter is a non replacement filter.
Exceptions are if the filter is damaged or has been removed and re-installed (will leak).
It won't hurt to replace it, but you are just throwing your money away.
Better to just change the fluid every 45k or so...
Subaru does not recommend changing the filter unless it's damaged.
