I was told by a dealer the other day that if I bought a 550xp that I would have to use husky chain oil or the warranty would be void and also that there was a sensor in the tank so when plugged into a laptop will tell husky what has been used!

I had never been in the shop before and will never go back.

Some dealers are a wee bit better than others.

FUEL HANDLING Fuel Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Mixing ratio 1:50 (2%) for all engines. Gasoline, litre Two-stroke oil, litre 2% (1:50) 5 10 15 0,10 0,20 0,30 0,40 US fl. oz. 2 1/2 6 1/2 12 7/8 ! Gasoline WARNING! Always ensure there is adequate ventilation when handling fuel. 20 US gallon 1 2 1/2 5 Mixing • • Use good quality unleaded gasoline. The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage. When working with continuous high revs (e.g. limbing) a higher octane is recommended. • • Always mix the gasoline and oil in a clean container intended for fuel. Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. Mix (shake) the fuel mixture thoroughly before filling the machine's fuel tank. Do not mix more than one month's supply of fuel at a time. If the machine is not used for some time the fuel tank should be emptied and cleaned. We recommend the use of special oil (chain oil) with good adhesion characteristics. • Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Ethanol fuel HUSQVARNA recommends commercial available fuel with maximum 10% ethanol content. Running-in Avoid running at a too high speed for extended periods during the first 10 hours. • • • Two-stroke oil • For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two stroke-engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). Never use oil intended for four-stroke engines. Chain oil • • • • • • • 20 - English Never use waste oil. This results in damage to the oil pump, the bar and the chain. It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. In temperatures below 32°F (0°C) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. Contact your service agent when choosing chain oil.

 

So basically they don't give specs for what type of oil to use which is a bit scary, due to that it would be fairly hard to turn down a warranty claim.
