I found this site which has been the most helpful for me for finding oil/fluid capacities for my ute when servicing.
Im a bit of a newby and just getting into doing all the work on my truck myself so I didn't know all the capacities and levels.
For some reason I could never find the oil capacity for my 5L-E hilux engine on the net until I found this - I used to play it by ear.
Someone else may find it useful too - hope I'm not telling anyone to suck eggs cos i'm a dimwit!
