Just a note to tell you how much I think of your products. Back in 1983 my next door neighbor was a chainsaw dealer for NE Kansas and Missouri. He sold me a Husqvarna chainsaw and told me to only run Optimal in it, which he had just started selling. The saw is still going strong cutting 5 to 10 cords of hardwood a year and the only problem I’ve had is an oil pump and a new spark plug every other year. The engine still starts on 2nd or 3rd pull and still cuts down big oaks with no problem. I use it in all my 2 cycle engines and have never had any engine problems. The only problem is I think the saw is going to out last me. I would stand by this product over all the others.
