My truck is rated for up to 20% biodiesel, which is the current maximum allowed, I believe. I've heard talk that the max may be raised to 30%. And if that happens, what are we expected to do, especially those with older trucks rated for B5 ?
This is just like when ethanol started getting added to gasoline. Folks with older cars could have problems (alcohol is also a great solvent and cam harm nonresistant seals and gaskets). It affected boat tanks and I always had problems using it in small engines such as lawn mowers, even though I treated the fuel.
