Yep...and use synthetic motoroil after your breakin period
(Mobil 1, Redline...) search the threads for suggestions...I go with Mobil 1
edit: oh, and obiously change the filter out as well (one of the reasons we run the engine after a new oil change is to fill the filter and re-check for the new level)
I sometimes go with K&N (high oil flow) or PureOne (it's cheap and good)
When you feel confident enough, try chaning both the manual transmission and rear differential fluid (gear oil) w/ synthetics....reccomend Redline...its makes your gearbox feel as if shifting in butter.
