You can order Amsoil on-line, and you don't need to buy it from a dealer. You can join as a preferred member for $20 a year, and it will give about 20% discount on all products. I have been using Amsoil now for over ten years, and recommend it highly. I've used Mobil 1 before in my 4-Runner and it didn't perform as well as Amsoil!
I have just gotten and oil change done last Friday on my 2008 GS350, and wow! The engine runs smoother with increase in acceleration! Can't wait to see an increase in mileage as well. It may take about two tankfuls to see the increase.
I use Mobil 1 simply because it is available in every autoparts store. In addition, WalMart carries the 5qt jug at the best price of anyplace. Amsoil is no where near that available.

This is very true...
If my guy that is right down the street didn't stock amsoil I wouldn't use it in the BMW. However Redline which I also have to order for my Harley is hard to find...but I still use it because IMHO and many other Harley riders it is the BEST! I always have enough top off fluid left over so it isn't a big deal...just is a pain to order it vs. going to WALLYWORLD and buying it!
