Very good oil especially for its price. I am now on the 4th liter and I use it on a Nakayama lawnmower and chainsaw. I mix it with a little castor oil in a ratio of 80/20 and I put 40:1 in the gasoline. It doesn't smoke at all and its smell is not very strong. I don't see any residue on the spark plugs, I haven't solved the engine yet since they still work perfectly.

I used both anonymous and branded oils and constantly faced issues with my tools (chainsaw, lawnmower). From the moment I started using this specific one, I forgot what damage means.

I have been using it for a year on a Chinese lawnmower and a Chinese chainsaw. It doesn't produce much smoke, almost none, and it seems to do a good job on the cylinder and piston.

It produced some black marks at the beginning but I had a ratio of 1:25. They told me to use a ratio of 1:45. Everything is fine. The machine is harvesting. I would recommend using a syringe for more accurate ratio. Very satisfied with the oil.
