After careful thought i really like the Unity line i have done lots of research and now have a chance to take the plunge however one issue remains the future of biodiesel <5
Since 2009, the state has required the use of a 2% biodiesel blend in all state-owned diesel-powered cars, and B20 biodiesel has become the rule, not the exception, at pumps around the state.
Illinois, incidentally, is not alone in its use of biodiesel fuel. Other states that require a biodiesel blend include Alabama (5%), Colorado (20%), Florida (not specified), Kansas (2%), Kentucky (2%), Maryland (5%), Massachusetts (15%), Minnesota (B20 to B100), Missouri (B20), Nebraska (not specified), New Mexico (5%), New York (not specified), Ohio (not specified), South Carolina (5%), Virginia (2%), and Washington (not specified).
A statement in a Mercedes-Benz Biodiesel Information publication makes the automaker’s position crystal clear: “Diesel fuels containing a higher percentage of biodiesel, (e.g. B6 to B20) according to ASTM D7467 as well as straight biodiesel (B100/100%) ASTM D6751 may cause severe damage to your engine/fuel system and are not approved.” In case there are any lingering doubts, one need only read the last page: “Any damages caused by the use of such non-approved fuels will not be covered by the Mercedes-Benz Limited Warranty.”
In the case of Mercedes-Benz, their advanced BlueTEC diesel engines inject some fuel on the exhaust stroke, but since biodiesel has a higher flash point than petroleum diesel, the biodiesel does not combust allowing the biodiesel to collect inside the crankcase of the engine itself. This crankcase sludging is irreversible and over time can lead to catastrophic engine failure.
These symptoms are showing up around 100k + - as i live in Canada the biodiesel is not a issue however the states and mexico are. As time goes by is biodiesel <5 getting hard to find in the states or mexico?
Any feedback would be appreciated
Thx Pat
