You need 10 characters to post. Good to know it's an Alloytec but still no reason to panic. Same deal with them, once they have a few kms moving to a 40 grade isn't a bad option, 50 won't see an Armageddon of puppies and kittens. Pre SIDI timing chain issues were a design flaw and Alloytec sludge problems were usually exacerbated by long service intervals that might end up even longer. 15k/12 months is very ambitious, most guys I know with Alloytecs go 5-7.5k.
