The impreza i bought had been sitting in a garage for 3 years and t'he owner only drove it every now and again. Ive now got it mot'd' and was wondering how i would go about changing t'he diff oil and how i would know if it needsa changed?many thanks davey

 

Dont know if they reccomend changing it, I'm not sure, was thinking this myself but what would you uselike EP80/90 or something.. Changing it should be easy though as is checking the levels theres two plugs, the lower is obviously the drain plug.

 

75W-90 is recommended weight, so yeah that'd do.
