I always do it myself and recommend a good synthetic oil like Royal Purple or AmsOil. The difference between mineral oil and synthetic is basically the usable life of the oil, wear protection, and anti friction properties. i'm no scientist so i can't explain to you why synthetic is better, but i suppose there's really no reason not to use it except for its price.

royal purple is expensive, $8/ qt. AmsOil is $7/qt and conventional is more like $4/qt. a reasonable price for a fully synthetic oil change is about $20 on top of material cost depending on which you choose.
