I change my oil every 10,000 miles because I use synthetic oil.
Ok, well I suppose I should listen to you...after all you've been doing this for quite a while. A Civic Ex probably wouldn't be a bad place to start anyway...in the lowest class. Then work my way up a little as I get better.
Is there a performance advantage to using synthetic oil? I've always just used what the dealer recommended.
