It's about time to change the oil in my burban. I was thinking of trying amsoil. Does anyone use this brand of oil.?

I've used it for years and love it. I've found though that most synthetics will serve you well and most are less expensive. I have a 2000 silverado with 130000 miles and it runs the same as when I got it with 38000 on it. 21MPG local driving. Still has th piston slap but it had done that all along.
