Holy crap, what is this? I go on Ebay and this guy has the 562xp and the 346 xp insanely jacked up. 5hp from the 346 and 5.8hp for the 562. The guy claims they will last for ever if you use some magic purple 100 to 1 oil and keep the air filter clean. What is your take on this guys? I am new to the saw deal but once had black magic trail port a new Arctic Cat for me and it turned into a high maintenance #####. He says regular gas and let her rip. Is he that good? One more thing, these saws are not cheap. Let me know what you think? Thanks, Russ
