I saw a UOA a while back, and it looked pretty good.
I also saw a VOA, and it looked pretty solid. I'm not sure I'd trust it for a really extended drain, and its price is approaching Amsoil/ Mobil EP/ EDGE etc... Thats probably why you dont hear about it much.
I spoke to their tech people, and theyre quite nice to deal with. Unfortunately, none of them seemed to know much about the product. Even their PDS sheet on the site is pretty sparse. For that reason and a few others, Ive shyed away from using it. I'm sure under a 5K interval, it would be PERFECTLY fine, and do well. It'd go futhur I'm sure, but far enough to justify the cost???? maybe, maybe not.
