I have just done an oil change to my Rover V8 Ford engine.
The manual states 5.21 liters. I threw 5 liters in, and a new oil filter, and it does not even register on the lower mark on the dip-stick.!
I will go and check add, until it does.
However in the booklet for the V6, it also says 5.2 liters, and I wonder if they might not have made a mistake and not corrected for the V8.
I will let you know.
