Welcome,
"I first started using synthetic motor oil in 1983. At the time, I owned a manufacturing plant and I had my own delivery trucks including an 18 wheeler. I had heard about synthetic oil and decided to use it in my trucks and autos full time.
I did more research into synthetics and found AMSOIL to be the highest rated synthetic oil on the market. In 2003, I switched all my vehicles over to AMSOIL motor oil, "Ea" oil and air filters, and other AMSOIL automotive products.
Now I change the oil and filter in my cars once a year -- including my 2001 Cheverolet Suburban that has over 195,000 miles and my classic '88 Mercury that has 73,000 original miles."
