I recently bought a used Toro 3650 snowblower as a back up for my other 3650. We had a hell of a winter here in Boston and need to run two machines at the same time..
This used blower had a tune up and spark plug change just before winter. The guy I bought it from was running Echo 2 cycle oil mixed at 50:1. When I changed the plug it was black and fouled. My other 3650 has been running for 3 years on the same plug using Opti-2 at around a 72:1 ratio. One packet per US Gallon. The plug was a very slight brown and had no oil build up whatsoever. It looked like new after 3 years and lots of hours !!!
This is good stuff. Thanks guys for a great product.
I’m not going to bother changing plugs anymore. I will wait until there are hiccups but I don’t expect any for a long while.
