When to change Amsoil
 

I see my manual calls to change the oil and filter every 8,000. Amsoil says you can go up to double that amount with their synthetic oil. I have about 3000 miles on it and about 9 months. I was going to change it but I guess I should wait. The oil is still clean so i think i will wait a while. At least 5000 or 1 year. What do you guys do?
