Contaminates
Contaminates will KILL ,anyway i have run Castrol Syntec
since i bought my notch in sep of 91,and even though i don't put a lot of miles on it a year (1800 to 2100mi.) castrol told me to change it every 6 months ,because of the short jaunts that i drive it on (nice weather ,weekends) the reason is condinsation in the block.
and then when i do change it ,it may only have 600 mi on that oil
(hard 600) so it may sound expensive to some but thats on me.
anyway change your oil , no more than 5000mi. on a daily driver
