I just purchased a new Husky 580 BTS blower (will be here tomorrow) and was wondering if you guys do a "break in period" with new equipment? If you do, do you use a conventional 2 stroke for the first couple of gallons and then either a semi-synthetic or a full synthetic? I have the Echo PB 770T, which I've had for 5 years and I can't for the life of me remember doing a break in period and I've been using the Echo Red Armor oil.
