I have been using Amsoil since my first Mustang. (1990 coupe). That car now has about 350,000 on it. Thats why I became dealer for them. Now I use it all my cars. From engine oil to rearend. 07 Mustang, 02 F350, 07 Fusion, 07 H-D Heritage,98 Explorer Sport. I know it is expensive but it is more than worth it. My friend changes his oil once a year. He just change the filters every 4 to 6000 miles. He also sends the oil to Blackstone labs to run tests on it.
