Either one is a good buy, frankly. With the updates to the 562 it's pretty bulletproof and the performance from them is incredible. The 620 is built great, performs great and will give you reliable service for years. There's a significant price difference between the two, so there's something to consider there. Also, the D176 bar mount the 620 uses will introduce some caveats in finding specialty bars and chain loops locally that you likely wouldn't encounter with the Husky. The Husky D009 mount is heavily supported by all major aftermarket manufacturers. Drive link counts are standard 84DL for a 24". The Echo is going to be 81DL and a little bit of an oddball if you need something in a pinch.

Hey! It's called Chain Locker, we have them on our website. They began with a pro model for longer bars but it's not fully available yet. 372 already had HD air filter setup, not necessary to change.

The oil nowadays is much higher quality than it was years and years ago. Updates to the lubricity and formulations have made it unnecessary to run higher concentrations of oils. The oil conversation is an age old argument people have that is considered somewhat of an inside joke between guys that have been following chainsaws as a hobby on social media/forums and more. A lot of people have rather SUBJECTIVE takes on it and not a whole lot of substance to back it up. Frankly, most failures can be explained, and replicated, again and again. It's HIGHLY unlikely that throughout all of the bearing failures that these saws were noted for that every user ran the same mixture of oil. The bearing failures were explained through research teams at Husqvarna. The root causes in this case were attributed incorrectly installed oil seals, inadequate mass in the case to dissipate heat and ineffective air filtration that allowed fine particulate past and into the case.

Thanks for the reminder
