Not to highjack the thread and I am NOT a rep or network marketer or involved at all but... Amsoil is the real deal and their products are good, expensive, but good. An aquaintence of mine sells the stuff and he is into all things "easy money"!! You know the dude
But I will say that anything amsoil I have ever tried in anything showed evidence of great results. I am not mechanic but when you go out to your car in below zerow weather and it starts up with a quick VROOM as if it was summer and does not go woop......wooop......woooop.......vroom to get going there is clearly oil moving - good stuff.
Stuff may be voodoo medicine but when I see the temp guage running significantly lower after it is added/used there is something good going on in there.
Truth is oil has come a LONG way and the competition is stiff so there are many great synthetics available, not just amsoil. I run synthetics in everything.
I also use Motorkote in all my equipment because I believe in it and the inventer is from Charlotte Michigan. I have seen his tests and it shames any other "Super Lube" out there without doubt. My 250,000G 16yr old, hard used Tahoe is my personal proof so I poor a little in my saw, quad, splitter and any other gas/oil engines now and then. I like Seafoam too.
I am a maintainence guy and just feel better if I have done the little stuff along the way. For me it is like my personal competition with the thermostat - I feel like I am winning if my engines last, run good and never see the repair shop. Run em like you stole em but maintain em like you paid retail!!
