take the time to check your filters too...any clog or deteriation can kill gas mileage/perfomance...and always replace your oil filter when doing an oil change.

the plug for the oil change should be on the rear side of the engine block, mine (d16y8) has an arrow pointing to "OIL"...remove it and be ready for the oil to start pouring out, so make sure your oil catch pan is positioned properly. and wear some rubber gloves cause you'll undoubtedly get at least a little oil on your hands. drain = 15 mins depending on temp, will probably take an hour to do a clean and thorough job...good luck :thumbup:
