I bought a case of Castrol SFX synthetic blend filters made by Champion Labs: the CAS7317 fits my Honda, Infiniti and former Subaru. Usage on the Outback was fine. But after 2,000 miles on the Honda I noticed some seepage from the oil filter gasket. I always hand tighten 3/4 to a full turn. When I noticed the leak, I used a wrench to tighten it another 1/4 turn. Is this small leak just a question of needing an extra little turn or would it be a defective gasket?
