If this is pointed at me, I did not like the white bottle oil because it was plugging up my spark arrestors. The black bottle does not do that. I also do not like the white bottle because it is JASO FB and not JASO FD. The black bottle is. I actually traded back a full case of the white even up for a case of the black bottle.
I use Amsoil in the summer when the heat is really on here in FL. I run Amsoil in my equipment and vehicles. I am not a dealer, I have a commercial account because I am a business and they give the same price or less than the dealers pay to commercial account people.
I am not spamming anyone. I use Stihl oil from November through March here when the cooling power of the Amsoil is not needed like durring the summer months when my 2 cycle gear is being nuked in heat.
