We present a simultaneous measurement of the B0bar lifetime tau_B0 and 
B0B0bar oscillation frequency Delta_md. We use a sample of about 
50000 partially reconstructed B0bar --> D*+ l- nubar decays 
identified with the BABAR detector at the PEP-II e+e- storage ring 
at SLAC. The flavor of the other B meson in the event is determined 
from the charge of another high-momentum lepton. The results are
tau_B0   = (1.504 +/- 0.013 (stat)  {+0.018}/{-0.013} (syst)) ps, 
Delta_md = (0.511 +/- 0.007 (stat)  {+0.007}/{-0.006} (syst)) ps-1
