What I'd really like to know is who makes what oil. That would end bunches of mine's better claims. I've bought my oil from a local hardware store in boxes of 50 one gal packets for about 15 years. In that time the boxes have said Poulan syn oil, Husky syn oil and it's name brand " ". I've always found the company's name in fine print on the box just to be sure. If I bought that same oil, doubled it's content and resold it as 50 to 1 mix, absolutely no one would know. Nor would it be a lie.
As fun as arguing the point is, it's kinda moot if you don't know who makes the oil you use.

So the thread keeps going. Mines better! Syn oils start with dino oil and they extract the good stuff and sell the leavings as "Penns oil"
Actually I just can't use Pennsoil because I was taught a long time ago that they get their oil from ash oil deposits back east and that oil comes out of the ground very dirty and gritty and full of ash. Maybe they get it real clean now but old habbits are hard to break.

Pe Whole industries are selling products that offer molecular bonding of lubricants to wear surfaces. Thats the prime reason for Syn oils. If the stuff is taking 5 hours to scuff off versus 1 and holding it's properties in the process to me that would indicate a 500% improvement. That alows 5 hours for new molecules to find a place in line to keep the process going.
