Hi guys, I have a couple of 254 XP's and a brand new 435 that I use for keeping the homefires burning and some occasional heavy duty farm use. I always used to mix oil as per the mixer bottle lines (50:1 I think) but read something a week or so ago that people are running higher a % of oil, I just wanted to hear what the pro's had to say about this. At my current use I reckon my saws will last me for eon's, so if a little more oil is good then I would be keen. Also, on the 435 - is there anything I can do to it to improve it without changing it too much - I don't want to run it harder than it should and risk killing it too early. From what I have read it is an entry level Husky saw and a decent saw - I like it but anything to watch for?
