I know junk science when I see it.
This is misleading journalism preying on the the uninformed, pure and simple.
Notice that even in an article the purports to expose the negatives regarding ethanol in gas, it still has incorrect "factoids/assumptions" to uneducate readers?
How long has it been since journalism was an "honorable" profession?
Bravo, TT.
In January, the Environmental Protection Agency approved gasoline-ethanol blends up to 15 percent ethanol, called E15, in cars, light trucks and sport utilities built after 2000. The E15 waiver raised a decades-old cap of 10 percent on ethanol blends for general use.
"APPROVED"? FORCED is the operative word...
In these bikes, the fuel hoses turn stiff in about 1 season from this alcohol, as do the O-rings in the tees that feed the carbs. If not monitored, this leads to fuel leaks that can easily cause engine fires.
Or lawn-mower fires, as noted above.
In cars, like several of mine, with carbs, the situation is similar, requiring a fuel hose change about every 2 years or else the hoses get so stiff that the hose clamps won't keep the fuel inside anymore. The gaskets in the carbs dry out and shrink, causing vacuum leaks and forcing a rebuild about every 3 years. IMHO, it's always been 90% about legislating the older vehicles off the road, and 10% giving subsidies to farmer groups to obtain votes...
I'd better stop, or I'll get on a rant...
One thing that can help slow down the effects of this crap is to add top oil, like diesel fuel (REAL diesel fuel) or one of the commercially available varieties, about 1-2 ounces per 5 gallon fillup. I was consistent about this for a long time after gasohol apeared here, then stopped for a while, developed the leaks and hard hoses, then started using it again (with new hoses). I use the Bardahl or Valvoline top oils, as they come in convenient bottles with 2 ounce caps.
