the oil story is a huge scam.
I ran around looking for oil for my V8. This is a Ford automatic, which is supposed to use a Mercon grade oil.
The local Ford dealers don't even use that! they fill with a Dexron grade oil.
Then I started to check and found a
Castrol ATF that claims to be Dexron AND Mercon compatible!!
That, plus the fact that Jatco, the supplier of Rover boxes, is a Nissan supplier where special oils are not specified! makes me say:
Anyone thinking Rover's autoboxes are different from Nissan's are dreaming.
Thus any specific oil requirements for the Rovers is just hype.
I have therefore just used good quality Dexron in my rovers for the last 4 years, no problems, whatsoever.
Go figure!
