I am an Amsoil preferred customer and run Amsoil in all my cars. It is one of the few oils that is actually tested to go for extended drain intervals.
Anyway, I was skeptical about using it in our cars, as they do not have traditional fuel injectors and instead have direct injection. I called the Amsoil tech line and they confirmed that it was safe to use. I have been using it since I got the car with 7,000 miles on it. I now have 43,000 miles. I have never had any issues. I am on my original fuel pump as well. Just my 2 cents.
