This is the dirty secret hiding in the closet people don't want to talk about: Smaller block-size engines putting out more power are lighter, but they burn up sooner. This is why Husky guys love light and powerful Huskys, STIHL guys love long-lasting STIHLs, and ported guys love blippy-rippers.....Same story with the 395XP vs 066/661. The 661C gets the nod for weight and ergos when putting face cuts in big timber, but the orange cinder block has the torque and double the oiling volume. Really shines when the bar is 42” plus, even if they did put the tensioner in the wrong spot.
Of course there's a strong argument the EPA regs choke off a saw's ability to perform at its best, the "government condom." But those are the forces the bearings and shell are designed to handle, and making more power is going to generate more wear; I think we just have to accept that given there's also "more fun on tap."
