About oil I like synthetic myself, but my son is a mechanic and during his studies for certificaton came across a study were Pensoil came on top. As far as wiper blades I buy the bosh brand just because they come in the required 21" sizes and most others dont. Lights Wagner make really good bulbs but be careful and ensure that you buy them all with the nickel/silver finish the ones with brass finish will make your dummy light on the dash go bonkers.
