how long should you wait before switching to synthetic oil? i know if you buy a new car, you should break it in with the OEM oil, which is probably conventional..., but how long until you can/should switch to synthetic?
i'd say japanese because they tend to be more reliable and have a much much much bigger aftermarket support in case you're into that.
if you want sporty though, id go with the GTI. since a 4door ex civic isnt as sporty.
if you want reliable/economical, id say go with the civic
