I'm using motor oil I believe... I replaced it about 4000 miles ago.. I'll have to check the oil level again. There isn't a dipstick for the manual transmission is there? If I rmemeber correctly there is a lugnut i unscrew and fill up to that line.

...but.. if I jack up one end of the car up to get underneath the car, how can I can an accurate level?? Jack stand all four corners?
