yes since we started to carry opti-2, opti-4 we have been using the opti-2 2cycle fuel mix in all the equipment that comes thru the shop. this stuff chemnically rebuilds the cylinder walls, which increases compression which increases the rpms. little to no smoke. we run it in snowblowers, chainsaws, trimmers, ice augers,
Now I can throw away all my small specail mixtures (32:1,40:1,50:1) and just make one batch of 100:1 with the opti-2 and I'll be good all over.Thanx MECH12
