“I was recommended to use this oil in my sports car with a Rover 3.9lt unit, these engines do suffer cam and follower wear and this oil is supposed to stick to the surfaces and form a wear surface esp when the engine is cold and with hydralic tappets can be noisy when started.
From the first turn of the key having having changed the oil i noticed a huge improvment, marked difference in engine noise and it runs so smoothly, very impressed so far”
