This stuff is amazing. I went through a phase of trying to find the best two stroke oil available and have a lot of open but unused bottles of various synthetic/syn blends sitting in the garage now that I have finally settled on opti. I have heard great things about optimol from people in the forestry industry and lcos. And opti 2 is just a newer formulation. I use opti in my many vintage two stroke engines from old 16:1 chainsaws, vintage 16:1/32:1 lawnboys to my new husqvarna 50:1 strimmer. These lawnboys have had a service life before I found them and bring them back to life. I used to use Dino oil at 32:1 only in them but that was so smokey and it was normal to have to clean exhaust ports and still run into low compression issues from wear or rings sticking. Opti at 80:1 (I mix a bit richer) has eliminated carbon issues and I have brought compression back to old engines. I also use vintage mowers commercially and only use opti 2 in my fleet. I own a lot of equipment and some sit for months without use and with the optimizer stabilizer they always start in most. 2 pulls or so.I am a lifer.
