Chris - I'd forgottem about this graph !
As they say a picture is worth a thousand words.
Also If the oil should overheat for any extended period - I was told over 200degC for over 5 mins then its best to change it. This was only achieved when I ran a 400cu.in tuned chev engine at air temps of around 30deg.C - I only saw temps over 200deg.C after around ten hard laps (Kyalami circuit) where revs were never below 3500 and usually over 5000.
And no I did not have an oil cooler installed.
Good info graph from Wilf /Chris
