Has anyone noticed that castrol tts now comes as castrol power 1 tts and it has now changed colour to red.
I bought a couple recently and wondered if anyone had noticed this. It still says that its fully synthetic but i have also noticed they sell castrol r2 racingbike?
Will it be ok to mix old and new oils or should the system be run down low until the oil light comes on then drained to make way for the newer oil?
Would you think power 1 tts is still the best castrol oil available or would this r2 racingbike oil be a better bet for oil pump use?
