I have always used mobil 1 and so have you. We both have had no problums. Both amsoil and mobil 1 are great motor oils. If the amsoil is cheaper then I say, give it a shot! Amsoil claims you can go 24,000 miles or 1 year before and oil change. I would never do that!!! However, amsoil is supposibly better for cold cold winters than mobil 1. Were i live, and at my work (murray's automotive) amsoil is over a dollar more a quart! The last 2 oil changes i have done I have been using Lucas synthetic oil stabilizer and I am in love with the product!! You should give it a try. If you can find it! It takes place of a quart of oil.
