Greetings 2-stroke fans. This will be my second testimony to the prior of 4 years ago. 4 years in the running has really put this product to the test for me. I purchased a new saw since my last review and used opti from the get-go. It has been 4 years using this saw in full time forestry along with splitting fire wood (yes splitting) about 5 cord per year and the saw still runs as the day it was purchased. But that is not my big awesome. Another saw I have that I had been using with the Opti for about a year went down on me right in the middle of a big job. It made a lot of noise when trying to restart so i set it aside for some time and ordered the rebuild parts based on experience. During disassembly I had found that the cylinder had loosened up in turn creating a massive lean condition. First thoughts where SAW IS FRIED. Much to my amazement only the crank and bearings had failed. The cylinder and piston were perfect, the 2 things that should have went first. If using standard oil that saw would have been junk. That’s my big awesome. Interlube corp, thank you again for a great product that may just do more than intended. No reason for me to ever try anything else unless it is new and improved from Interlube. Happy 2-stroking every one.
