Other synthetics are not better than Amsoil and will cost more to use, eliminating the need to buy them. If other synthetics were identical, then yet, by all means use them, but they are not. Amsoil is superior to Mobil 1 and Castrol.
My last oil change was about $60 or so on my car (double the $$ of yours), but I have over 70,000 miles on my car and my oil has been changed only 4 times and my gas mileage has increased over 4 MPG. I would have changed it 24 times doing it the conventional way. Instead of using 144 quarts of dino oil, I only used 24 quarts of Amsoil. Not a bad deal.
So if you really want to get down to the details... think of it if I didn't use Amsoil and used whatever cheap dino oil I could buy at Walmart and change it every 3,000 miles like most people do...
I was getting 29 MPG before Amsoil. Do the math...
72,000 miles / 29 MPG x $2.10/gallon = $5,213 in fuel (the cheap oil route)
72,000 miles / 33.7 MPG x $2.10/gallon = $4,486 (The Amsoil way)
Amount saved in fuel so far: $727
That's much more than I paid for the Amsoil. That means all of my oil was FREE! The oil paid for itself.
This is why I keep preaching to people about it. It makes no sense to use other oils or other synthetics. Amsoil is cheaper and better than anything on some store shelf or any quick lube.
The only people who shouldn't be using Amsoil are the ones who simply don't know about it. Now that I've told you all about it, everyone here should be researching it and ordering it for their next oil change. Use it the way it's made to be used with the extended drain intervals and you will be amazed. Trust me. Every friend and relative I've ever got to switch, they all now rave about it.
