I want to try Amsoil's 5W30 but I'm concerned because it's not API certified. What is the reason for this?
Can you really go 25,000 miles between changes? Are there any UOA's on Amsoil after 25K and what did they look like?
How does Amsoil 's 5W30 compare to Mobil 1 SuperSyn?
Will Amsoil 5W30 harm my engine?
Is there any store I can buy Amsoil at in my area? Or how could I go about ordering it?
