How often to change Castrol Syntec Synthetic oil? I heard you can wait longer than normal oil?

I don't know that Castrol recommends extended drains with Syntec. Look into Amsoil synthetics if you want to go to once a year oil changes. Here's a couple data bulletins on the synthetic oil and filters: amsoil.com/lit/databulletins/…" rel="nofollow">amsoil.com/lit/databulletins/… amsoil.com/lit/databulletins/…" rel="nofollow">amsoil.com/lit/databulletins/… Here's an article on extended oil change intervals vs. 3mo/3,000 miles: amsoil.com/redirect.cgi?zo=14… Europeans have been doing 10,000 miles or more on their motor oil for years!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
