"Calibre" 10W 30 oil

[The Monty]

Just a heads up, used this on my last oil change, about 3-4000 k's in, car was starting to get noisy on start ups, sticky lifter would start sticking if I gave it any juice, etc. Should have emptied it right then, but waited for the 10 000 k's I usually do (mostly highway K's).
Anyway, after 10 000 relatively easy K's compared to usual (not much thrashing, no drag nights/skid pan days), and changed the oil to find it so black, and like dead set water, there is no resistance there at all, the oil is just dead.
So my little warning, steer clear of it, avoid it, Ive gone back to my Castrol.
