There never has been anyone here or on other sites, that I am aware of, that has proben any supperiority of fullsynthetic over semisynthetic. So if anyone has any proof, I am all ears. Although to be honest, at the moment I use full synthetic, but a generic brand where the same amount costs less than the semisynthetic brand name. 7

I think it fried because it couldn't cool off, the fins were packed with 5 years of caked in sawdust and neglect on my part. This was one of hardest run saws that is pretty much on a constant basis making ripping cuts with the grain, lot of fine sawdust for hours a day. Assuming I was running a 40:1 for the last 5 years instead would it have fried because of the same reason? If it was too lean why would it run day in and out for 5 years? That seems like an awfully long time to run. I have a new 490 echo that I may try and run 40:1 in and see how long that lasts compared to my amsoil 80:1 490.

80:1 is simply not enough oil for a chainsaw. I would say this saw would have run longer at 40:1 than it did under those conditions.
I doubt it seriously! If the outside is packed, there is nothing in the world that will save it, if it can't cool off in prolonged cuts.
