It is the best oil for "gumming" motors I've ever seen.
I lost a Zephyr Zodiac engine to Castrol.
I had a Peugeot 504 dump oil on the ground through long use of Castrol and a pressure relief valve seizing.
Recently, my brother lost the 5 litre V8 in his 1994 Statesman, at 120,000km. Holden in Adelaide, always put Castrol in it. 12 years later we put a full detergent oil in it, and the car went for 30 km, then lost oil pressure and died. He now has a second hand low km V8 in it with GOOD oil. When we took the valley cover off the old motor, the sludge was similar to my old Zodiac.
Castrol is the pits!
