;The California legislature recently considered a bill requiring automotive engine oils to be certified by thier manufacturer to have a service life of 10,000 miles. this bill has been "held " this session so it is dead for now. It's purpose is to reduce used ; oil .

;The point here is that Amsoil has synthetic engine oils that will meet and exceed the 10,000 mile service life. Our XL series lubricants are good for the first occurance of 10,000 miles or 6 months of service. Amsoil's Signature Series lubricants have a service of life of the first occurance of 25,000 miles, 700 hours of operation or one year in normal passenger car service.

;By specifying Amsoil lubricants you can protect the environment and your engines while saving time with longer maintenance intervals. Shop now.
