I'm trying to find out what the Australian owner's manual recommended oil viscosity is for the modular V8's.
As you may know, the Yanks have gone crazy and Ford is recommending a 5W-20 in all new engines.
Holy binding bearings Batman!
So, does the Australian owners manual say 0W-40, 5W-30, 10W-30 15w-40 or ?????????
Thanks in antissssssssssssssipation.
