This is the best chain oil I have tried. It’s hard to judge oil since the bad or good effects can take a while to set in but this stuff seems to be the best with my use so far. There are some cheap oils out there that I’ve ran into before, usually making the chainsaw not run as smooth, but it seems so much smoother with this oil. I highly recommend skipping out on all the others and getting this oil to prevent any possible wear and tear.
