hmmm - never heard of the blue lined tube ... also haven't had any issues using gasohol in my 283, since rebuilt about 15 years ago - in fact we've had E10 here for over 20 years - I've always used it with no ill effects, and always heard that 10% isn't enough to cause problems .... might have more to do with low quality parts?
concerning the short "self life", I've been using the snowblower the past week, running fine on the 1/2 tank of gas left from last January ... and in a very humid climate
