Husqvarna HP 2 Cycle Engine Synthetic 50:1 Oil Mix 5.2 oz.

I'm a model airplane enthusiast. I've been flying radio control airplanes for over 20yrs. We run gasoline 2-stroke engines that are extremely similar in size and operation to a chainsaw. The engines range in size from 20cc up to 200cc or larger. Most of the engines myself and other guys at the club are 20cc -- 100cc engines. We operate these engines in the 7,000 -- 10,000 RPM range. I've run more than 160 gallons of fuel through 3 different engines using Husqvarna XP+ oil. I pull spark plugs and muffler as part of regular maintenance, every 8--10hrs of operating time. They're all clean! No carbon build up in the ring grooves. No carbon on top of the pistons. No carbon in the exhaust ports. Clean transfer ports. Bearings are all smooth. Plugs are tan and look totally normal. Dry and tan but it's a light camel hair tan. No oil fouling anywhere. I'm in for another gallon. That will last me about a year.

Have never had a problem with it. Works good on my weed eater.
