They used lighter oils the cam chopped out 3 times. They went to a heavier oil grade the cam was OK! (Are there any petroleum engineers on List?).
Penrite website says :- "HPR 10 Semi-synthetic SAE 10W-50 wide range viscosity engine oil formulated for use in a wide range of latest generation petrol fuelled motor car and recreational 4WD engines." "HPR 15 An SAE 15W-60 semi-synthetic engine oil formulated for use in latest technology multivalve- multicam computer managed or conventional engines "HPR 30 High viscosity, non friction modified SAE 20W-60 oil formulated for use in conventional engines and latest multivalve, multicam, computer managed engines operating under a high load environment" The lighter oils are designed for engines with lighter valves and less lift. These engines do not get the same shear conditions you get in older two valve engines.
