Toyota recommends 0W-20 with an OCI of 10K for a 2011 4Runner with a 1GR-FE engine.
Toyota recommends 5W-30 with an OCI of 5K for a 2010-2013 Tacoma with the 1GR-FE engine.
I looked up piston ring set, crankshaft, connecting rod and main bearing part numbers for the 2011 Tacoma. Most of those parts show "also fits 4Runner" or have the same part numbers. Only 1 out of 15 bearing sets has a different part number between the two vehicles. Both engines are dual VVTi. Oil capacity difference is 1.1 quarts for the 4x4 vehicles.
I'm wondering why a difference for the recommended OCI and viscosity. Any ideas?
