Yeah but Amsoil sells a whole litany of different lubes and oils that cover a wide variety of machines. Oil, grease, gear lube, etc.
How many autos are running BRP/DOO oil? Probably none. Amsoil, I'd say there's quite a bit more.
Hence the reason I think Amsoil can be sold cheaper, volume. If you don't think BRP/DOO is marking up their "special formula", I don't know what to tell you. Do you think they add $20+ worth of additives per gallon? I find that difficult to believe but who knows.
As many have said, it's really up to each person to make their decision with the plus/minus of what can happen. For me, Mystik has been outstanding and I've got the miles and valves to prove it. To each their own.
XPS also has a wide range of product offering, not just 2 stroke oil.
And of course they're marking up thier "special formula" - just like every other oil on the market.
Also, if you're paying $20.00/more a gallon for XPS vs Amsoil you're getting ripped off. I bought XPS last year for $33.00/gallon. Show me where I can by Amsoil for $13.00/ gallon and I'm in! I looked around the net some, the cheapest I found it was $34.65/gallon.
Again, I'm not saying ANY of these oils are bad, I was just trying to put a little perspective on some of the wild claims being made here.
It's your sled, burn what you want. Just keep in mind if something bad happens you might have some finger pointing going on. And as I've always said, of course eventually you'll most likely win, but how much time and effort will be exhausted in the mean time. With XPS you're not just buying oil, you're buying a little bit of an insurance policy too.
On the linked test, good info, decent oil, but notice how some parts got heavier with Amsoil. Gotta be from carbon buildup, yes?
