I've had my 460 rancher almost 3 years now and have never ran anything but Husquvarna 2 cycle oil and 90 octane non ethanol gas. I was cleaning my garage and found 2 large unopened bottles of 2 stroke oil. One Poulan brand and the other Walmart brand (SuperTech). My wife and I are both out of work and not wanting to spend any more money than we have to. So my question is, does anyone see any issue using these oils? I have a tons of trees to cut and figure this is a good opportunity to use up this oil I found without having to buy the OEM stuff. What is your opinion or experience using cheaper s cycle oil?
