That is what I was thinking, but then I realized I work in a nuclear power plant, and we use top of the line materials for everything, and a lot of our fluid systems only get changed yearly. And we run the **** out of them. 100+ degree ambient temps,salt water, sand, you name it.

But as Billy said, a saleman's job is to sell. But Amsoil has been around for a long long time, if it was junk, it would go away. Sort of like Sham-wow, those things were being peddled when I was 6 years old, I remember. They work, they are still around today, but you don't need to spend 30 bucks on them. Same as Amway, they sell good products, but the pyramid concept gives them a bad name.

Hmmm, seems I have already made up my mind, but at 5K miles a year, who cares.......My VX is quickly becoming a trail rig, and my Expedition now has 18K miles, it is two years old and has driven cross country 3 times. That tells you how little I drive around.
